UK study shows how LDTs may one day enable physicians to identify patients genetically predisposed to chronic disease and prescribe lifestyle changes before medical treatment becomes necessary
Could genetic predisposition lead to clinical laboratory-developed tests (LDTs) that enable physicians to assess patients’ risk for specific diseases years ahead of onset of symptoms? Could these LDTs inform treatment/lifestyle changes to help reduce the chance of contracting the disease?
A UK study into the genetics of one million people with high blood pressure reveals such tests could one day exist.
Researchers at Queen Mary University of London and Imperial College London uncovered 535 new gene regions affecting hypertension in the largest ever worldwide genetic study of blood pressure, according to a news release.
They also confirmed 274 loci (gene locations) and replicated 92 loci for the first time.
“This is the most major advance in blood pressure genetics to date. We now know that there are over 1,000 genetic signals which influence our blood pressure. This provides us with many new insights into how our bodies regulate blood pressure and has revealed several new opportunities for future drug development,” said Mark Caulfield, MD,
Professor of Clinical Pharmacology at Queen Mary University of London, in the news release. He is also Director of the National Institute for Health Research Barts Biomedical Research Centre.
The researchers believe “this means almost a third of the estimated heritability for blood pressure is now explained,” the news release noted.
Clinical Laboratories May Eventually Get a Genetic Test Panel for Hypertension
Of course, more research is needed. But the study suggests a genetic test panel for hypertension may be in the future for anatomic pathologists and medical laboratories. Physicians might one day be able to determine their patients’ risks for high blood pressure years in advance and advise treatment and lifestyle changes to avert medical problems.
By involving more than one million people, the study also demonstrates how ever-growing pools of data will be used in research to develop new diagnostic assays.
The researchers published their study in Nature Genetics.

Genetics Influence Blood Pressure More Than Previously Thought
In addition to identifying hundreds of new genetic regions influencing blood pressure, the researchers compared people with the highest genetic risk of high blood pressure to those in the low risk group. Based on this comparison, the researchers determined that all genetic variants were associated with:
- “having around a 13 mm Hg higher blood pressure;
- “having 3.34 times the odds for increased risk of hypertension; and,
- “1.52 times the odds for increased risk of poor cardiovascular outcomes.”
“We identify 535 novel blood pressure loci that not only offer new biological insights into blood pressure regulation, but also highlight shared genetic architecture between blood pressure and lifestyle exposures. Our findings identify new biological pathways for blood pressure regulation with potential for improved cardiovascular disease prevention in the future,” the researchers wrote in Nature Genetics.
Other Findings Link Known Genes and Drugs to Hypertension
The UK researchers also revealed the Apolipoprotein E (ApoE) gene’s relation to hypertension. This gene has been associated with both Alzheimer’s and coronary artery diseases, noted Lab Roots. The study also found that Canagliflozin, a drug used in type 2 diabetes treatment, could be repurposed to also address hypertension.
“Identifying genetic signals will increasingly help us to split patients into groups based on their risk of disease,” Paul Elliott, PhD, Professor, Imperial College London Faculty of Medicine, School of Public Health, and co-lead author, stated in the news release. “By identifying those patients who have the greatest underlying risk, we may be able to help them to change lifestyle factors which make them more likely to develop disease, as well as enabling doctors to provide them with targeted treatments earlier.”
Working to Advance Precision Medicine
The study shares new and important information about how genetics may influence blood pressure. By acquiring data from more than one million people, the UK researchers also may be setting a new expectation for research about diagnostic tests that could become part of the test menu at clinical laboratories throughout the world. The work could help physicians and patients understand risk of high blood pressure and how precision medicine and lifestyle changes can possibly work to prevent heart attacks and strokes among people worldwide.

Employers and consumers continue to pay more for health benefits from one year to the next, continuing a trend that is not auspicious for clinical laboratories and anatomic pathology groups
Most clinical laboratories don’t have the capability to collect payments from patients at time of service the same way patients pay doctors during office visits. Thus, Milliman’s annual report which details the increasing amounts patients are expected to pay out of their own pockets should be of interest to clinical laboratory managers and stakeholders. As this trend accelerates, labs will need to adopt new procedures and technologies to conduct business and remain profitable.
The Milliman Medical Index report (MMI) details how much consumers are predicted to pay for healthcare each year, as compared to previous years. Milliman, a Seattle-based independent actuarial and consulting firm with offices throughout the world, examines healthcare costs, property and casualty insurance, life insurance, financial services, and employee benefits.
Milliman released its first MMI in 2005. That year, the average annual medical cost for a family of four was $12,214.
Both Employees and Employers to See Increase in Healthcare Costs
The 2018 MMI report provides both good and bad news for the healthcare industry and patients. Milliman examined the costs for a typical family of four that participates in an employee-sponsored health insurance plan. For the report, a family of four consists of a 47-year old male, a 37-year old female, and two children under the age of five.
The MMI estimates a family of four will spend an average of $28,166 in healthcare expenditures in 2018. Included in this amount is the cost of the insurance paid by the employers and the employees, deductibles and out-of-pocket expenses. The figure represents an increase of $1,222 from 2017. The report found the amount families have been paying for healthcare has been increasing by an average of $100 per month over the last ten years.

Both employers and employees will see an upsurge in costs from last year with employees experiencing an increase of 5.9% and employers seeing an increase of 3.5%.
The MMI found that employees will pay approximately 44% of their healthcare costs in 2018. By contrast, in 2008 employees paid less than 40% of their healthcare expenditures. In 2018, employers will pay about $15,788 of healthcare costs for a family of four, the employee will pay $7,674 via payroll deductions, with the remaining $4,704 being out-of-pocket expenses.
Costs Increasing While Growth Slows
The MMI also found that while the dollar amount families are spending on healthcare is increasing, the overall pace of the growth is slowing. The 4.5% rate of increase over last year is the slowest percentage growth in 18 years.
“We asked key stakeholders across the healthcare system what might be driving the decline in growth rates,” said Sue Hart, co-author of the MMI, in a Milliman news release. “Several common themes emerged, in particular provider engagement, more effective provider contracting, value-driven plan design, and spillover effects from public program initiatives.”
The reasons cited for this slowing trend include:
- Involvement of healthcare providers to reduce costs;
- More sophisticated contracting and provider consolidation;
- Increased member cost sharing;
- High deductible health plans;
- Role of government and public programs; and the,
- Impact of pharmacy initiatives.
“There are two ways of looking at this year’s MMI,” said Chris Girod, co-author of the Milliman Medical Index, in the news release. “On the one hand it’s heartening to see the rate of healthcare cost increase remain low. On the other hand, we’re still talking about more than $28,000 in total healthcare costs for the typical American family.”
The MMI graphic above breaks down healthcare costs into their constituent categories. (Image copyright: Milliman.)
To explore how costs have grown, the MMI examined five separate components of services. The typical family of four spends:
- 31% ($8,631) of their healthcare costs on inpatient facility care;
- 29% ($8,257) on professional services;
- 19% ($5,395) on outpatient facility care; and,
- 17% ($4,888) on pharmacy services.
The remaining 4% ($995) of costs are spent on other services, such as:
- Home healthcare;
- Ambulance services;
- Durable medical equipment; and,
- Prosthetics.
The MMI measures costs for a typical family of four, but certain families or individuals may have variations in costs depending on such factors as age, gender, health status, geographic area, provider variation, and insurance coverage.
Prescription drug costs is one such variance that is hard to predict. The 2018 MMI determined drug costs for a family of four increased by 6%, which represents the lowest percentage increase since 2015.
“Prescription drug costs have steadied, but this trend is volatile and hard to predict,” said Scott Weltz, co-author of the MMI in the news release. “High-cost drugs can have a big impact on trends, as we witnessed a few years ago when hepatitis C treatments hit the market. Alternatively, point-of-sale rebates could push a consumer’s costs in the other direction, particularly for people taking high-cost drugs. As the environment evolves, changes in drug prices can be deployed quite quickly.”

These costs are increasing and could impact clinical laboratories unprepared to collect fees at time of service. (Photo copyrights: Milliman.)
Preparing to Accept Payments
The results of this year’s MMI illustrate the impact increasing consumer costs could have on the way clinical laboratories conduct business and receive payments for services rendered. Studies have shown that patients with high deductible health plans (HDHPs), who frequently must pay 100% of lab costs, are especially affected by these trends. And the numbers of patients on HDHPs have increased each year since they were enacted.
Many clinical laboratories and anatomic pathology practices do not have the capability to collect fees from patients at the time of service. This lack of preparedness could threaten the survival of those labs and should be addressed.

Many of the newer patient-centered technologies are those based on the concept of remote patient monitoring (RPM).
RPM is proving so beneficial for patients and healthcare professionals, it has touched off a new wave of innovation—that of microsampling blood collection technology.
Download the free White Paper
More technicians, and the clinicians who rely upon them, are adopting patient-centric technologies to improve the quality of patient care and thus support enhanced clinical outcomes. Included in this proliferation of new technologies are those based on concept of remote blood sampling using microsampling technology.
Remote patient monitoring through microsampling blood collection makes many aspects of healthcare less invasive and intrusive for patients, with the ability to participate in one’s care from the comfort and privacy of his or her home. Expenses associated with healthcare travel and long wait times are minimized, patients take more control over their treatment, and are often happier than those who need to travel to have illnesses and chronic conditions monitored.
Dark Daily is pleased to offer a recently published free White Paper that shares with laboratory professionals valuable and informative insights on how the field-changing technology of microsampling can answer the challenges of changing remote patient requirements.
“How to Create a Patient-centered Lab with Breakthrough Blood Collection Technology: How to Save Time and Increase Profitability by Using Modular Technology to Improve Access Features, Automate Reporting & Expand Efficiencies” details the ways in which new microsampling blood collection methods facilitate a more patient-centric lab, and provide a user-friendly alternative to older, more intrusive or cumbersome methods.
In addition, this complimentary White Paper provides labs with a practical, step-by-step roadmap to new microsampling technology adoption, deployment, and success.

Shift from fee-for-service to value-based reimbursement is fueling increase in joint ventures and co-branded insurance products, creating opportunities for nimble clinical laboratories and anatomic pathology groups
As healthcare moves from fee-for-service to value-based reimbursement, health insurers and providers are joining forces at a steadily increasing rate, with nearly three-quarters of partnered products in early 2018 being joint ventures or fully co-branded insurance products. This trend presents an opportunity for clinical laboratories to help providers become more effective in their use of laboratory tests as they aim for better patient outcomes and lower treatment costs.
While health systems integrating with insurance services is not new, the roll out of the Affordable Care Act (ACA) in 2014 and its emphasis on value-based reimbursement helped create renewed interest in vertical integration, notes Becker’s Hospital Review.
According to consulting firm Oliver Wyman, the number of payer-provider partnerships has grown rapidly over the past six years, with 73% of the 22 insurance products launched in the first quarter of 2018 being joint ventures of co-branded offerings.
In comparison:
- 22% of partnerships were joint ventures or co-branded in 2014:
- 33% in 2015;
- 57% in 2016; and,
- 71% last year.
Of the 22 new payer-provider partnerships announced this year, 20 product announcements explicitly emphasized value-based compensation, while compensation was implied but not mentioned in the final two product-based partnerships.
“Payers and providers continue to be interested in forming product-based partnerships,” Oliver Wyman stated when releasing the new data. “Our analysis … continues to show a steady increase of trend toward deeper partnership, with more co-branding, greater levels of value-based financial alignment, and other forms of closer collaboration and joint ventures.”
Oliver Wyman cited several “notable” new entrants:
In addition, Oliver Wyman noted that national payers Aetna and Cigna added to their growing rosters of joint ventures in 2018.
Speaking with Healthcare Dive, Tom Robinson, Partner, Health and Life Sciences at Oliver Wyman, described this year’s new ventures as varying in type, size, location, and model. He noted that 50/50 joint ventures with co-branding have gained in popularity, however, accountable care organizations (ACOs), pay-for-performance, and bundled-payment models also are being formed. Robinson believes these vertical integrations offer opportunities for innovation.
“The point of these partnerships is to create something new, rather than just building the same old offerings with a narrow network,” Robinson said. “Successful partnerships will take the opportunity to innovate around the product and experience now that the incentives, insight, investment and integration are all for it.”

Lower Costs, Improved Access, Through Payer-Provider Partnerships
In announcing Blue Cross Blue Shield of Rhode Island (BCBSRI), and Lifespan’s launch of coordinated healthcare plan BlueCHiP Direct Advance, BCBSRI President and Chief Executive Kim Keck pointed to the plan’s ability to drive down healthcare costs.
“We hear a consistent theme from our members—they want more affordable health plan options—and through our collaboration with Lifespan we are doing that,” Keck stated in a news release. “BlueCHiP Direct Advance is an innovative product that features Lifespan’s vast network of providers who are positioned to more effectively manage and coordinate a patient’s care. And, our partnership allows us to offer this new product at a cost that is 10% lower than our comparable plans.”
When Allina Health System of Minnesota and Aetna last year announced their partnership plans, Allina Chief Executive Penny Wheeler, MD, praised the ability of “payer-provider” partnerships to improve care coordination and increase access to preventive care.
Jim Schowalter, MPP, President and Chief of Executive of the Minnesota Council of Health Plans, told the Star Tribune the joint venture between the for-profit insurer and local health system would accelerate the shift within the state to value-based care.
“This is another effort in our state that moves us away from old fee-for-service systems,” Schowalter stated. “Working together, doctors and insurers can deliver better personal care and hold down medical expenses.”
While the future of the ACA and other healthcare reforms is uncertain, clinical laboratories and anatomic pathology groups should expect healthcare networks and insurers to continue to find ways of partnering. That means pathologists can expect to have an expanded role in helping providers improve patient outcomes and reduce healthcare spending.

Silicon Valley startup is using gene sequencing to identify in the bloodstream free-floating genetic material shed by tumors
There has been plenty of excitement about the new diagnostic technologies designed to identify circulating tumor cells in blood samples. Now, a well-funded Silicon Valley startup has developed a blood test that it says holds promise for detecting early-stage lung and other cancers.
Though experimental, the screening test—which uses gene sequencing to identify in the bloodstream cancer-signaling genetic material shed by tumors—would be a boon for clinical laboratories and health networks. It also could play a role in advancing precision medicine treatments and drug therapies.
GRAIL, a Menlo Park, Calif., life sciences company, presented its initial findings at the 2018 American Society of Clinical Oncology Annual Meeting in Chicago. Its lung cancer data is part of GRAIL’s ongoing Circulating Cell-Free Genome Atlas (CCGA) study, which aims to enroll 15,000 participants and investigate 20 different types of cancers.
“We’re excited that the initial results for the CCGA study show it is possible to detect early-state lung cancer from blood samples using genome sequencing,” said lead study author Geoffrey Oxnard, MD, Dana-Farber Cancer Institute and Associate Professor of Medicine at Harvard Medical School, in a Dana-Farber news release.
“There is an unmet need globally for early-detection tests for lung cancer that can be easily implemented by healthcare systems,” lead study author Geoffrey Oxnard, MD (above), said in the Dana-Farber news release. “These are promising early results and the next steps are to further optimize the assays and validate the results in a larger group of people.” (Photo copyright: Dana-Farber Cancer Institute.)
According to the news release, researchers in this initial analysis explored the ability of three different prototype sequencing assays, each with 98% specificity, to detect lung cancer in blood samples:
“The initial results showed that all three assays could detect lung cancer with a low rate of false positives (in which a test indicates a person has cancer when there is no cancer),” the Dana-Farber news release noted.
Identifying Disease Risk Before Symptoms Appear
Screening tests help identify individuals who are not displaying disease symptoms but may be at high risk for developing a disease. GRAIL’s goal is to develop a test with a specificity of 99% or higher. This means no more than one out of 100 people would receive a false-positive.
Otis Brawley, MD, Chief Medical and Scientific Officer at the American Cancer Society, points out that specificity is important when developing a population-based screening test that ultimately would be given to large portions of the general public based on age, medical history, or other factors.
“I am much more concerned about specificity than sensitivity [true positive rate], and [GRAIL] exhibited extremely high specificity,” Brawley told Forbes. “You don’t want a lot of false alarms.”
Some cancer experts have a wait-and-see reaction to GRAIL’s initial results, due in part to the small sample size included in the sub-study. Benjamin Davies, MD, Associate Professor of Urology at the University of Pittsburgh School of Medicine, and an expert on prostate cancer screening, told Forbes the early data was “compelling,” but the number of patients in the study was too small to generate excitement.
Oxnard, however, believes the initial results validate the promise of GRAIL’s blood screening test project.
“I was a skeptic two years ago,” Oxnard, a GRAIL consultant, told Forbes. “I think these data need to put a lot of the skepticism to rest. It can be done. This is proof you can find cancer in the blood, you can find advanced cancer, therefore this has legs. This has a real future. It’s going to be many steps down the line, but this deserves further investigation and should move forward.”
Next Steps
Researchers next plan to verify the initial results in an independent group of 1,000 CCGA participants as part of the same sub-study. They then will attempt to optimize the assays before validating them in a larger data set from CCGA, the Dana-Farber news release explained.
Illumina, a sequencing-technology developer, formed GRAIL in 2016, with participating investments from Bill Gates, Bezos Expeditions and Sutter Hill Ventures. Since then, GRAIL has attracted other high-flying investors, including Amazon, Merck, Johnson and Johnson, and Bristol-Myers Squibb.
Forbes notes that as of 2018 GRAIL has raised $1.6 billion in venture capital and has a $3.2 billion valuation, according to private market data firm Pitchbook. Last year, GRAIL merged with Hong Kong-based Cirina Ltd., a privately held company also focused on the early detection of cancer.
While GRAIL’s projects hold promise, anatomic pathologists and clinical laboratories may be wise to temper their enthusiasm until more research is done.
“We all would like to dream that someday you’d be able to diagnose cancer with a blood test,” Eric Topol, MD, Executive Vice President and Professor of Molecular Medicine at Scripps Research, told Forbes. Topol says he’s “encouraged” by GRAIL’s methodical approach, but warns: “We’re at the earliest stage of that.”

Diagnostic medical laboratories may sequence DNA genetic tests correctly, but there are issues with how companies analyze the information
In 2017, some 12 million people paid to spit in a tube and have their genetic data analyzed, according to Technology Review. Many companies offer this type of DNA testing, and each of them works with one or more clinical laboratories to get the actual sequencing performed. For example, Ancestry.com, one of the largest direct-to-consumer genetic data testing companies, works with both Quest Diagnostics and Illumina.
In the case of Quest Diagnostics, the clinical laboratory company does the actual sequencing for Ancestry. But the analysis of the genetic data for an individual and its interpretation is performed by Ancestry’s team.
There are critics of the booming direct-to-consumer genetic testing business, but it’s not due to the quality of the sequencing. Rather, critics cite other issues, such as:
- Privacy concerns;
- How the physical samples are stored and used;
- Who owns the data; and,
- That this branch of genetics is an area of emerging study and not clearly understood.
What Does All That Genetic Data Mean?
The consumer DNA testing market was worth $359 million dollars in 2017 and is projected to grow to $928 million by 2023, according to a report from Research and Markets. Those numbers represent a lot of spit, and an enormous amount of personal health information. As of now, some one in every 25 adults in the US has access to their genetic data. But, what does all that data mean?
The answer depends, in large part, on who you ask. Many reporters, scientists, and others have taken multiple DNA tests from different companies and received entirely different results. In some cases, the sequencing from one sample submitted to different companies for analysis have rendered dramatically different results.
“There is a wild-west aspect to all of this,” Erin Murphy, a New York University law professor and genetics specialist who focuses on privacy implications, told McClatchy. “It just takes one person in a family to reveal the genetic information of everyone in the family,” she notes. (Photo copyright: New York University.)
It’s All About the Database
Although some people purchase kits from multiple companies, the majority of people take just one test. Each person who buys genetic analysis from Ancestry, for example, consents to having his/her data become part of Ancestry’s enormous database, which is used to perform the analyses that people pay for. There are some interesting implications to how these databases are built.
First, they are primarily made up of paying customers, which means that the vast majority of genetic datasets in Ancestry’s database come from people who have enough disposable income to purchase the kit and analysis. It may not seem like an important detail, but it shows that the comparison population is not the same as the general population.
Second, because the analyses compare the sample DNA to DNA already in the database, it matters how many people from any given area have taken the test and are in the database. An article in Gizmodo describes one family’s experience with DNA testing and some of the pitfalls. The author quotes a representative from the company 23andMe as saying, “Different companies have different reference data sets and different algorithms, hence the variance in results. Middle Eastern reference populations [for example] are not as well represented as European, an industry-wide challenge.”
The same is true for any population where not many members have taken the test for a particular company. In an interview with NPR about trying to find information about her ancestry, journalist Alex Wagner described a similar problem, saying, “There are not a lot of Burmese people taking DNA tests … and so, the results that were returned were kind of nebulous.”
Wagner’s mother and grandmother both immigrated to the US from Burma in 1965, and when Wagner began investigating her ancestry, she, both of her parents, and her grandmother, all took tests from three different direct-to-consumer DNA testing companies. To Wagner’s surprise, her mother and grandmother both had results that showed they were Mongolian, but none of the results indicated Burmese heritage. In the interview she says that one of the biggest things she learned through doing all these tests was that “a lot of these DNA test companies [are] commercial enterprises. So, they basically purchase or acquire DNA samples on market-demand.”
As it turns out, there aren’t many Burmese people taking DNA tests, so there’s not much reason for the testing companies to pursue having a robust Burmese or even Southeast Asian database of DNA.
Who Owns Your Genetic Data?
As is often the case when it comes to technological advances, existing law hasn’t quite caught up with the market for ancestry DNA testing. There are some important unanswered questions, such as who owns the data that results from a DNA analysis?
An investigation conducted by the news organization McClatchy found that Ancestry does allow customers to request their DNA information be deleted from the company’s database, and that they can request their physical sample be destroyed as well. The author writes, “But it is a two-step process, and customers must read deep into the company’s privacy statement to learn how to do it. Requests for DNA data elimination can be made online, but the company asks customers to call its support center to request destruction of their biological sample.”
Another concern is hacking or theft. Ancestry and similar companies take steps to protect customers’ information, such as using barcodes rather than names and encryption when samples are sent to labs. Nevertheless, there was an incident in 2017 in which hackers infiltrated a website owned by Ancestry called RootsWeb. “The RootsWeb situation was certainly unfortunate,” Eric Heath, Ancestry’s Chief Privacy Officer, told McClatchy. He added that RootsWeb was a “completely separate system” from the Ancestry database that includes DNA information.
What We Don’t Know
The biggest pitfall for consumers may be that geneticists don’t know very much about DNA analysis. Adam Rutherford, PhD, is a British geneticist who interviewed for the Gizmodo story. He said that the real problem with companies like Ancestry is that people have a basic, fundamental misunderstanding of what can be learned from a DNA test.
“They’re not telling you where your DNA comes from in the past. They’re telling you where on Earth your DNA is from today,” Rutherford told Gizmodo.
Science evolves, of course, and genetic testing has much evolving to do. The author of the Gizmodo piece writes, “It’s not that the science is bad. It’s that it’s inherently imperfect.” There aren’t any best-practices for analyzing DNA data yet, and companies like Ancestry aren’t doing much to make sure their customers understand that fact.
Nevertheless, issues surrounding genetic testing, the resulting data, and its storage, interpretation, and protection, continue to impact clinical laboratories and anatomic pathology groups.
