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.

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.

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.

Attack on computer systems worldwide highlights critical importance for hospitals and medical laboratories to regularly update IT infrastructure and software
While Internet connectivity and automation are changing the landscape of both healthcare and diagnostic testing facilities, it is also creating new ways for things to go catastrophically wrong. The WannaCry ransomware attack on May 12th highlights the critical need for hospitals, medical practices, pathology groups, and clinical laboratories to constantly update the software and systems powering much of their healthcare continuum.
After infection, the ransomware encrypts 179 different file types on the system it’s attacking. It then demands payment in bitcoins to remove the encryption and restore access to files. Clinical laboratories should be wary of any suspicious e-mail attachments and apply security updates to vulnerable systems as soon as possible. (more…)

As cognitive and cloud computing continue to advance, and mobile technologies become more accessible across the globe, innovative apps and mobile attachments are using algorithms to replace the need for complex and time-consuming diagnostic tests
Mobile healthcare—also known as mHealth—is attracting plenty of research dollars as entrepreneurs look for ways improve consumers’ access to various medical services in ways that could reduce healthcare costs. For that reason, some mHealth solutions may be used by clinical laboratories and pathology groups to give patients faster access to diagnostic services and information about medical laboratory tests.
Most mHealth solutions excel at doing a single, defined task well. In some cases, they are faster and as accurate as human-based testing or observation. However, few solutions can tackle complex diagnostics, such as determining the pathogens involved in sepsis. And mHealth cannot replace the human element of communication and empathy, which will always have a place in the medical process. (more…)

As chronic disease and aging populations strain the UK’s medical systems, staffing shortages at pathology laboratories contribute to lengthening delays of critical diagnostic services
In the United Kingdom (UK), pathologists and other physicians are going public with their concerns that a growing shortage of pathologists and medical laboratory scientists will soon contribute to delays in performing the lab tests needed to diagnose patients—particularly those with cancer—and identify which therapies will work best for them.
Thanks to vast improvements to both medical laboratory capabilities and treatment options, the cancer survival rate in the UK doubled over the past four decades. However, early diagnosis is a critical component to a successful outcome. As further strain is placed on medical laboratories and diagnostic providers, wait times continue to increase beyond the thresholds created by the UK’s National Health Service (NHS).
Worsening an already dire situation, a November 2016 report from Cancer Research UK, “Testing Times to Come? An Evaluation of Pathology Capacity Across the UK,” predicts a critical shortage in laboratory staffing within the next decade. Data on Provider-based Cancer Waiting Times for August 2016 from National Health Service England shows that 17.2% of patients with an urgent referral for suspected cancer fail to start treatment within two months of the referral.
