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.

Pathologists around the world will be interested to learn that, for the first time in the UK, prostate cancer has surpassed breast cancer in numbers of deaths annually and nearly 40% of prostate cancer diagnoses occur in stages three and four
Early detection of prostate cancer, and the ability to identify its more aggressive forms, are important goals for every nation’s health system. However, a new study in the United Kingdom (UK) will be of interest to all anatomic pathologists handling prostate biopsies. Researchers determined that late diagnosis of prostate cancer is an issue that should be addressed by healthcare policymakers in the UK.
In 2015, deaths due to prostate cancer surpassed those of breast cancer in the UK. According to data from Cancer Research UK, this trend continued into 2016 with 11,631 deaths from prostate cancer and 11,538 deaths from breast cancer. The trend continued even though breast cancer saw roughly 8,000 more new cases in 2015, according to the same data.
Now, a report from Orchid—a UK male cancer charity—highlights a trend that should interest medical laboratories and histopathology (anatomic pathology in the US) groups that analyze prostate cancer samples. They found that 37% of UK prostate cancer cases involved diagnoses in stages three or four.
Late-Stage Diagnosis of Prostate Cancer: The US and UK Compared
“With prostate cancer due to be the most prevalent cancer in the UK within the next 12 years, we are facing a potential crisis in terms of diagnostics, treatment, and patient care,” stated Rebecca Porta, Chief Executive of Orchid, in a press release. “Urgent action needs to be taken now if we are to be in a position to deliver world class outcomes for prostate cancer patients and their families in the future.”

The latest data from the Centers for Disease Control and Prevention (CDC) on prostate cancer and mortality rates in the US shows an interesting picture. In 2014, 172,258 men received a prostate cancer diagnosis. However, deaths from prostate cancer were at 28,343.
According to Statista, an international statistics portal, the UK is home to more than 32.3-million males. And, Statista’s data shows the US is home to 159.1-million males. This implies that despite the US having nearly five times the number of males, the number of prostate cancer deaths/year in the UK is significantly higher in relation to population size.
Cancer Research UK notes that despite decreasing by 13% in the last decade, prostate cancer mortality rates are still 21% higher than in the 1970s.
Awareness and Early Detection Key Components in the Fight Against Cancer
A study published in BMC Public Health offers one possible explanation for this disparity.
“When compared to analogous countries in Europe, Canada, and Australia, older adults in the UK have markedly different survival outcomes,” noted lead author of the study Sara Macdonald, PhD, Lecturer in Primary Care at the Institute of Health and Wellbeing at the University of Glasgow, Scotland.
“Poorer outcomes in the UK are at least in part attributable to later stage diagnoses,” she explained. “Older adults should be vigilant about cancer. Yet, this is not reflected in the news media coverage of cancer risk. Taken together, invisibility, inaccuracy, and information overload build a skewed picture that cancer is a disease which affects younger people.”
While treatment options have improved in the past decade, early detection is a key part of successful treatment—especially as prostate cancer has both aggressive and slow variants. Effective timely health screening also is of critical concern.
In the US, however, prolific prostatic-specific antigen (PSA) testing and other screenings for chronic disease—particularly within the elderly population—is under increased scrutiny and criticism, which Dark Daily reported on in April. (See, “Kaiser Health News Labels Routine Clinical Laboratory Testing and Other Screening of Elderly Patients an ‘Epidemic’ in US,” April 11, 2018.)
New Tools to Detect Prostate Cancer
Faster diagnosis and the ability to detect whether a prostate cancer is slow or aggressive could help to shift these numbers around the world.
According to BBC News, the NHS hopes to reduce diagnosis times and make the screening process less invasive by using magnetic resonance imaging (MRI). Hashim Ahmed, PhD, Chairman of Urology, Imperial College London, told BBC News, “Fast access to high-quality prostate MRI allows many men to avoid invasive biopsies as well as allowing precision biopsy in those men requiring it to find high-risk tumors much earlier.”
A team from the University of Dundee is trialing a shear wave elastography imaging (SWEI) process to detect prostate tumors as well. Speaking with The Guardian, team leader and Chair of the School of Medicine at The University of Dundee, Dr. Ghulam Nabi, noted, “We have been able to show a stark difference in results between our technology and existing techniques such as MRI. The technique has picked up cancers which MRI did not reveal. We can now see with much greater accuracy what tissue is cancerous, where it is, and what level of treatment it needs. This is a significant step forward.”
Should these tools prove successful, they might help to reverse current trends in the UK and offer greater insight and options for the histopathology groups there, as well as the medical laboratories, oncologists, and other medical specialists helping to treat cancer.
Until then, raising awareness and streamlining both detection and treatment protocols will remain a critical concern, not just in the UK, but around the world as the human population continues to age.

CMS sends letter to Orig3n notifying the genetic test company that it may not have the required certifications to market its genetic tests
Orig3n’s recent ill-fated “DNA Day” promotion to offer free genetic tests during an NFL football game this past fall pushed Orig3n into the media spotlight. The Massachusetts-based biotech company—which sells 18 different DNA tests on its website—suspended the promotion due to questions from the Centers for Medicare and Medicaid Services (CMS) and the Maryland Department of Health (MDH) regarding the legality of the testing under the Clinical Laboratory Improvement Amendments of 1988 (CLIA).
Since then, however, new details from BuzzFeed and GenomeWeb indicate that Orig3n may not have the required certifications to market their genetic tests after all. On October 30, 2017, CMS served Orig3n with an out-of-compliance notice. According to BuzzFeed, the letter came from Karen Dyer, MT (ASCP) DLM, Director, Division of Laboratory Services and the CLIA program at CMS.
In a letter to Kate Blanchard, Chief Operating Officer at Orig3n, Dyer wrote, “To apply for CLIA certification, Orig3n must contact both the Massachusetts and California state agencies immediately for guidance. Orig3n’s various tests analyze 18 genes related to health, from ‘muscle power’ to ‘sugar sensitivity’ to ‘age-related metabolism’. It offers genetic testing that provides information for the assessment of health.” The letter gave Orig3n a November 13 deadline to update CMS on issues regarding their CLIA certification.
Robin Smith, CEO, Orig3n, told GenomeWeb the notice “was the first time that any clear guidance was given regarding specific genes and requirements for CLIA/non-CLIA.” He also noted efforts Orig3n undertook over the prior year to fully certify their laboratory.
The test shown above is one of 18 genetic tests Orig3n offers direct to consumers. According to Vice, Orig3n claims their tests do not require FDA-approval “because the tests are not diagnostic [and] they don’t require it.” The Baltimore Sun reported that “Orig3n is confident it can receive the proper approvals and plans to have a fan giveaway later this season at one of our games.” (Photo copyright: Orig3n.)
Fortunately for Orig3n, meeting compliance and obtaining certification for their existing lab is no longer a requirement to resolve the issue. In a November press release, Orig3n announced the purchase of Interleukin Genetics. Orig3n plans to absorb Interleukin’s existing assets, including a CLIA-certified genetics laboratory in Waltham, Mass., capable of analyzing more than one million samples annually.
“Once we met with Interleukin Genetics, we saw a natural alignment between the two organizations regarding our shared commitment to a future of personalized health,” Smith noted. “With our trajectory of accelerated growth, we couldn’t imagine a better fit for acquisition. We are very pleased to be welcoming Interleukin Genetics to Orig3n.”
GenomeWeb asked Blanchard how the acquisition would impact Orig3n’s commercialization of the 18 tests in question by CMS, now that Orig3n owns a CLIA-certified lab, and through it, meets the requirements of CMS’ out-of-compliance notice. Blanchard declined to comment.
New Concerns Surrounding Interleukin Assets
Yet, in solving one set of problems, some experts believe Orig3n might have inherited a new set. In July 2016, GenomeWeb reported that Interleukin Genetics would be laying off 63% of its staff. Unable to secure a clinical services agreement, the company could not extend debt payment deferrals with its senior lenders. At the time of writing, debts totaled $5.6 million.
Further complicating matters, a 2015 peer-reviewed analysis published in the Journal of the American Dental Association (JADA) questioned the clinical validity of an inflammation management program called “Ilustra” that Interleukin claimed, “identifies individuals with an increased risk for severe and progressive periodontitis, due to a life-long genetic predisposition to over-produce Interleukin-1 (IL-1), a key mediator of inflammation.”
Another GenomeWeb article reported on the turbulent road the Ilustra program followed until Orig3n eventually pulled it from the market. GenomeWeb noted critics’ concerns about the marketing of precision medicine, genetic testing, and regulatory issues facing medical laboratories as these technologies mature.
Clinical Laboratories Continue to Field Concerns Over DTC Testing
“This [genetic] test would have been laughed out of the room if it had been presented to oncologists, or to professionals in medical genetics,” declared Scott Diehl, PhD, co-author of the JAMA analysis, a genetics researcher at Rutgers School of Dental Medicine, and Professor and Principal Investigator at Rutgers Biomedical Health Sciences.
GenomeWeb notes in their latest coverage that with Orig3n’s purchase of Interleukin Genetics, Diehl is once again concerned that the genetic tests in question might find their way back to the market.
When GenomeWeb questioned Orig3n about the concerns surrounding Interleukin’s Ilustra product, a spokesperson stated, “that was simply before Orig3n’s time with the company and they do not have a part in it.” Blanchard added, “[We are] looking at the entire Interleukin portfolio and implementing the tests if and when we decide it is appropriate.”
Regardless of the decisions made by Orig3n on future genetic tests and genetic service offerings, coverage of this event highlights a myriad of concerns—from regulatory scrutiny to the pitfalls of acquiring existing diagnostic tests or laboratory assets—facing clinical laboratories, anatomic pathologists, and other medical professionals working in the ever-shifting landscape of the modern healthcare system.

Owlstone Medical’s breath biopsy platform takes aim at breath biomarkers for an earlier diagnosis of cancer; could it supplant tissue biopsies sent to pathology labs?
For many years, medical laboratory scientists and pathologists have known that human breath contains molecules and substances that have the potential to be used as biomarkers for detecting different diseases and health conditions. The challenge was always how to create clinical laboratory test technology that could use human breath samples to produce accurate and clinically useful information.
Stated differently, breath, the essence of life, may contain medical laboratory test biomarkers that could provide early-detection advantages to pathology groups in their fight against cancer. Now diagnostics company Owlstone Medical—developer of the Breath Biopsy platform—is about to conduct a clinical study in collaboration with the United Kingdom’s (UK’s) National Health Service (NHS) and others to demonstrate the effectiveness of its breath-based diagnostic tests.
Anatomic pathology groups and clinical laboratory leaders know human breath contains volatile organic compounds (VOCs) that can be useful diagnostic biomarkers for medical laboratory testing. Many possible breath tests have been researched. One such test, the urea breath test for detecting Helicobacter pylori (H. pylori), has been in clinical use for 20 years. As part of the test, patients with suspect stomach ulcers or other gastric concerns, swallow a tablet with urea and exhale carbon dioxide that is measured for H. pylori bacteria.
According to an Owlstone Medical news release, the new study, called the “PAN Cancer Trial for Early Detection of Cancer in Breath,” will explore the ability of Owlstone Medical’s Breath Biopsy platform to detect cancers of the:
Current medical care standards call for these cancers to be diagnosed by analyzing biopsied tissue specimens. If Owlstone Medical’s breath test performs well during trial, it could provide advantages over traditional tissue-based cancer testing that include:
- A non-invasive approach to finding cancer earlier;
- A lower price point as compared to a tissue biopsy cancer test; and
- Faster return of test results, since tissue would not need to be collected from patients during surgical procedures and sent to medical laboratories for analysis.
“By 2030, the number of new cancer cases per year is expected to rise to around 22-million globally. Some cancers are diagnosed very late when there are few treatment options available. Non-invasive detection of cancer in breath could make a real difference to survival,” stated Richard Gilbertson, PhD, Li Ka Shing Chair of Oncology, Director of the CRUK Cambridge Center, and Oncology Department Head at University of Cambridge, in the news release.
How the Breath Biopsy Platform Works
The Breath Biopsy platform relies on Owlstone Medical’s Field Asymmetric Ion Mobility Spectrometry (FAIMS) technology, which the diagnostics company explains is a “fast means to identifying volatile organic compound biomarkers in breath.”
Billy Boyle (above), co-founder and Chief Executive Officer at Owlstone Medical, demonstrates the ReCIVA Breath Sampler. “Positive results from the PAN cancer trial could be game-changing in the fight against cancer,” he noted in the news release. “Success in this study supports our vision of saving 100,000 lives and $1.5 billion in healthcare costs.” This technology has the potential to be disruptive to anatomic pathology, which relies on the analysis of biopsied tissue to detect cancer. (Photo copyright: Owlstone Medical.)
Here is how FAIMS works in the Breast Biopsy platform, according to the Owlstone Medical website:
- Gases are exchanged between circulating blood and inhaled fresh air in the lungs;
- VOC biomarkers in the body’s circulation system pass into air in the lungs, along with oxygen, carbon dioxide, and other gases;
- Exhaled breath contains those biomarkers exiting the body;
- Because it takes one minute for blood to flow around the body, a breath sample during that time makes possible collection and analysis of VOC biomarkers of any part of the body touched by the circulatory system.
One publication compared the capture of VOCs to liquid biopsies, another possible non-invasive cancer diagnostic technique being widely researched.
“The advantage to VOCs is that they can be picked up earlier than signatures searched for in liquid biopsies, meaning cancer can be diagnosed earlier and treated more effectively,” reported Pharmaphorum in its analysis of five technology companies fighting cancer.
As part of the clinical trial, breath samples will be collected in clinic settings with the hand-held Owlstone Medical ReCIVA Breath Sampler (equipped with a dime-sized FAIMS silicon chip). The samples will come from people with a suspected cancer diagnosis who are seeking care at Cambridge University Hospital’s Addenbrooke’s Hospital. To test reliability of the biomarkers, breath samples from patients with cancer and without cancer will be analyzed.
“You’re seeing a convergence of technology now, so we can actually run large-scale clinical studies to get the data to prove odor analysis has real utility,” stated Owlstone Medical co-founder and Chief Executive Officer Billy Boyle, in a New York Times article.
Breath Tests Popular Area for Research
The company’s Breath Biopsy platform is also being tested in a clinical trial for lung cancer being funded by the UK’s NHS. The study involves 3,000 people, the New York Times article reported.
This is not the first time we have reported on Owlstone Medical. A previous e-briefing explored the company’s technology in a study focused on diagnosis of lung cancer (See Dark Daily, “In the UK, Pathologists Are Watching Phase II of a Clinical Trial for a Breathalyzer System That Uses Only a Breath Specimen to Diagnose Lung Cancer,” May 11, 2015.)
Breath tests in general—because they generally are non-invasive, fast, and cost-effective—have been the subject of several other Dark Daily e-briefings as well, including those about:
Owlstone Medical’s ability to get backing from Britain’s NHS, as well as investments to the tune of $23.5 million (the most recent coming from Aviva Ventures) is a positive sign. That Owlstone Medical’s Breath Biopsy platform is credible enough to attract such respected collaborators in the cancer trials as the Cancer Research UK Cambridge Institute (CRUK), University of Cambridge, and Cambridge University Hospitals (CUH) NHS Foundation Trust is evidence that the company’s diagnostic technology is considered to have good potential for use in clinical care.
Medical laboratory managers and pathology group stakeholders will want to monitor these developments closely. Once proven in clinical trials such as those mentioned above, breath tests have the potential to supplant other medical laboratory diagnostics and perhaps lower the number of traditional biopsies sent to labs for diagnosis of cancer.

National Health Service estimates 73% of 65-million urine specimens collected annually in the UK are contaminated
Wanting to know why so many female patients that present with urinary tract infections (UTIs) require repeat appointments, Dr. Vincent Forte, a family GP and forensic physician who worked for the National Health Service (NHS) for 26 years, began investigating. He determined that the standard urine specimen collection cup is primarily the cause of poor-quality medical laboratory test results.
Forte realized that the method of collecting the specimens was largely to blame, with the required “start-aim-start” midstream collection technique required by traditional polypropylene specimen cups at the root of the problem.
That realization led to the development of a unique “midstream” urine collection device that eliminates the problem of first-void urine contaminating samples, according to a blog post on the Royal Society for the encouragement of Arts, Manufactures and Commerce (RSA) website written by Forte Medical of London’s Founding Director and Chief Executive Officer Giovanna Forte, Vincent Forte’s sister.
65-million Specimens Deemed Unreliable
Healthcare professionals, whether working in clinical laboratories and anatomic pathology groups or hospitals and out-patient clinics, often are among the first to notice when gaps in the quality or integrity of medical laboratory test results exist. However, in this case, it was a general practice physician rather than a medical laboratorian or in vitro diagnostics (IVD) manufacturer that set out to solve the problem of poor urine specimen collection, which The Daily Telegraph reports results in 73% of the 65-million urine specimens collected annually by the NHS being unreliable. That’s 47.5-million unreliable medical laboratory specimens collected and tested yearly in the United Kingdom.
Accurate Urine Collection Brings Billions in Savings
Vincent Forte concluded that the quality gap in urine specimen collection for his female patients was preventing accurate first-time analysis, diagnosis, and targeted treatment. In 2001, he set out to re-engineer urine collection cups. His first design—“a simple flushable paper funnel, which rejected first-flow urine, collected midstream, and ejected the remainder”—established the underlying design principle behind the patented Peezy Midstream product, Giovanna Forte stated in the RSA blog post.
Giovanna Forte noted that the first version of the device, marketed in 2010, was a “funnel formed by flat-sheet film, with a unique container-acceptor,” with overflow duct and incorporating a compressed sponge that rejects the first 8-10 ml of urine. While the product was well received, Forte says the selling price was too expensive to meet the NHS requirement for cost savings. By 2012, the product evolved into an injected-modeled design, which cut production costs by 50%. By 2014, the ergonomically designed funnel was improved to incorporate the two most common urine collection tubes.
In a Forte Medical presentation, Giovanna Forte predicted that accurate urine collection could result in a £1.2-billion (US $1.56-billion) savings to the NHS.
A Design Week article described the testing process for developing the midstream specimen collection device as “similar to launching a website in beta,” with initial testing resulting in changes such as the creation of a flatter, rounder handle to make the product easier to hold.
“Within the NHS, I was allowed to attend clinics where evaluations were taking place and speak directly to the patients. This allowed me to find out what they thought of everything from instructions for use to the collection system itself,” Vincent Forte stated in the Design Week article. “All the information was fed back into our design engineers, who proposed an improved product made more simply at a lower price.”
The patented Peezy Midstream urine collection system rejects the first (often contaminated) 8-10 ml of urine, isolating and capturing the important midstream and rejecting the rest of the urine into the toilet. The product claims 98.5% accurate urine specimen collection and would improve the accuracy and reliability of the medical laboratory tests performed on urine samples collected with this device. (Photo copyright: Forte Medical.)
Today, Forte Medical offers two midstream urine collection devices used by both men and women:
1. Peezy Midstream PE40, which collects urine into a traditional 30ml universal container; and
2. Peezy Midstream PE50, which collects urine into a lab-friendly 10ml primary tube designed to fit in laboratory analyzers.
“This simple solution … took 10 years and £2.6-million [US $3.38-million] to get right. It was achieved not by a multinational with deep pockets, but by a startup funded largely by friends, family, and a handful of angel investors, along with the goodwill of design and manufacturing partners,” Vincent Forte stated in the RSA blog post.
Specimen Capture Methods Lead to Careless Infection Control
In an article published on News Medical, an online, open-access medical information provider, Giovanna Forte points out another flaw in traditional urine collection systems.
“Thrusting one’s hands willingly into our own urine is hardly common practice. That we are expected to do so in order to capture an important specimen essential to diagnosis hardly chimes with the concept of modern medicine and leads to pretty shabby infection control by any standards,” she stated.
The Peezy Midstream is a Medicines and Healthcare Products Regulatory Agency (MHRA) approved product in the UK, and is FDA listed in the United States. As a Class 1 “Container, Specimen Mailer and Storage, Non-Sterile” device, the Peezy Midstream is “510(k) exempt” and did not require FDA review before being marketed in this country.
Still to come are clinical trials and papers in peer-reviewed medical journals that support the function of this medical device to improve patient care. It is notable, though, that the National Health System in the UK is collaborating with Forte Medical in certain ways to determine how the device can improve patient care. Dark Daily would like to hear from any medical laboratories in the UK and USA that are using this device when urine specimens are collected.
