Genalyte’s cloud-based Maverick Detection System could potentially change how and when doctors order blood draws, altering long-standing clinical laboratory workflows
Anatomic pathologists and medical laboratory leaders may be aware of efforts in the in vitro diagnostics (IVD) industry to perform clinical laboratory tests with smaller quantities of blood. The most high-profile company to try and fail is Theranos, which both Dark Daily and its sister print publication The Dark Report reported on as events unfolded.
So far, though, continued efforts to dramatically reduce the amount of blood needed for most typical medical laboratory tests have come up dry. But this has not stopped innovative companies from trying to do so.
One such company is San Diego-based Genalyte. The biomedical diagnostics developer has announced it is readying its new Maverick Detection System (Maverick), which, according to the company’s website, “completes a comprehensive battery of blood tests in the physician’s office with results in 15 minutes.”
According to a news release, “Genalyte is laying the groundwork to move the business of biomedical diagnostics online, with the idea of creating an integrated delivery service for test results that can be generated from a drop of blood.” If successful, Maverick may be poised to disrupt the phlebotomy and clinical laboratory industries in a big way.
Fifteen Minutes from Fingerprick to Clinical Lab Test Results
Maverick, according to its developers, “[will] send digital samples to the cloud for quality review before releasing to the physician and patient. Our central lab handles tests that cannot be completed onsite.
“At the core of our cloud-based, diagnostic laboratory offering is revolutionary technology that uses silicon photonic biosensors to perform multiple tests off a single drop of whole blood in 15 minutes,” notes Genalyte’s website.
In a MedCity News article, Cary Gunn, Genalyte’s founder and CEO, said, “There will always be a need for esoteric testing that needs to be referred to a laboratory. But for the vast majority of routine testing, there’s no reason why that can’t be done in the doctor’s office.”
How Maverick Completes Medical Laboratory Tests in Doctor’s Offices
According to Genalyte’s website, “The Maverick Detection System performs real-time detection of macromolecules in crude samples using biologically functionalized silicon photonic biosensors lithographically printed on disposable silicon chips.”
About the width of a pencil erasure, Maverick biosensor chips “are individually functionalized with unique probe molecules and are individually interrogated, making highly multiplexed analysis possible. As a sample flows over the chip, the probes on the sensors bind with their corresponding ligands. This binding results in a localized change in refractive index on the sensor surface; this change is directly proportional to analyte concentration.”
“The silicon chip itself is watching the chemical reactions take place. Anytime two molecules bind, we can see that happen. So, the technology is capable of almost an infinite number of tests,” Gunn explained in the MedCity News article.
According to the developer, test results are available “in 10-30 minutes depending on the type of assay performed.”
Cary Gunn, PhD, Genalyte’s Founder and Chief Executive Officer, said in a news release that the San Diego-based biomedical diagnostics company wants “to put a rapid and powerful suite of diagnostic tests in every physician’s office.” (Photo copyright: Genalyte.)
Pilot Studies Show Test Feasibility in Doctor’s Offices
The company also announced completion of two pilot studies of the platform’s effectiveness in performing anti-nuclear antibody (ANA) testing. The purpose of study “one” was to “evaluate the feasibility of using this novel instrument to perform ANA 8 tests in the clinic and to compare those results to the same sample tested in Genalyte’s CLIA registered laboratory.” Study “two” focused on “Detection of anti-nuclear antibodies for the diagnosis of connective tissue diseases (CTD).”
The ANA test is often ordered by physicians for diagnosis of CTDs, including:
• Rheumatoid arthritis;
• Systemic lupus erythematosus;
• Raynaud syndrome; and,
• Systemic scleroderma, according to an article in Rheumatoid Arthritis News.
“We are starting with rheumatology, but I call that our entry point,” Gunn told MedCity News. “Our goal is to decentralize the vast majority of diagnostic testing to be near the patient and near the physician.”
The two studies together involved about 750 patients, who were tested by Genaltye’s Maverick system over four months. Results of their blood tests, via fingerprick in the doctor’s office, were compared to traditional medical laboratory procedures and patient diagnoses.
According to the Genalyte video above, “The Maverick Detection System … directly detects the binding of proteins or antibodies to the sensor in real-time and results are analyzed simultaneously with the accompanying Genalyte software. Almost all of the most time consuming and expensive parts of assay development and sample testing are reduced or eliminated.” Click on the image to view the video.

According to the news release and the published clinical abstracts, the researchers concluded that:
• Positive and negative results on whole blood tested on the Maverick system highly correlated with serum tested on previously approved devices;
• Multiplex ANA testing on whole blood in physician offices is feasible;
• Venous draw and fingerstick blood samples highly correlated; and
• Maverick has the propensity to improve patients wait times for diagnosis and to enhance their testing convenience.
“There is extremely high correlation for absolute value between venous blood and fingerstick blood, and between positive and negative results seen with whole blood on the Maverick and serum on the FIDIS Connective 10,” noted study “one” researchers.
“I’m impressed,” Patricia Jones, PhD, former President of the American Association for Clinical Chemistry (AACC), told Bloomberg News. “The game-changing part of this would be being able to do testing and potentially make a diagnosis immediately, instead of having to send out lab tests, wait several days, and then call the patient,” she added.
Can One Drop Do It All? Some Researchers Advise Caution
The controversy surrounding point-of-care fingerprick capillary blood draws performed on in-office automated blood analyzers, versus clinical laboratory venous draws performed on high-volume laboratory systems, is not new. Dark Daily has reported on several blood test studies in the past.
One such study involved bioengineers at Rice University. It concluded that fingerpricked capillary blood may not be accurate or reliable enough for clinical decision-making.
Their study acknowledged the value of such capillary blood testing in remote areas. But it also urged caution about use of measurements from a single drop of fingerprick blood.
“Using both a hematology analyzer and POC hemoglobinometer, we found the variability of blood component measures to be greater for successive drops of fingerprick blood than for multiple drops of venous blood,” the researchers wrote in The American Journal of Clinical Pathology (AJCP).
Research will no doubt continue until a viable, accurate, and affordable blood analyzer system that conducts dozens of clinical laboratory tests based on a few drops of blood comes to market. It’s basically inevitable in today’s world where computers can be built from molecules and miniature medical laboratories can be placed in chips, skin patches, and needles.
Pathologists and clinical laboratory leaders would be well advised to monitor the development of these various new diagnostic technologies. For most of the past decade, there has been a steady parade of companies and research teams announcing new discoveries that could revolutionize clinical diagnostics as performed today. However, few disruptive clinical laboratory tests or analyzers based on these technologies have made it into the clinical marketplace.

November workshop to teach Clinical Lab 2.0 to forward-thinkers among clinical laboratories, IVD manufacturers, and lab IT vendors offered many examples where clinical laboratory diagnostics can add value and improve patient outcomes
DATELINE: ALBUQUERQUE, New Mexico—Here in this mile-high city, a special Project Santa Fe Workshop devoted to teaching the principles of Clinical Lab 2.0 attracted an impressive roster of innovators and forward-thinkers in clinical laboratory medicine. In attendance were leaders from a select number of the nation’s first-rank health systems and hospitals, along with executives from In Vitro diagnostics (IVD) manufacturers, lab IT companies, other lab service companies, attendees from the Centers for Disease Control and Prevention, and from institutions in Canada, Germany, Israel, India, and the UK.
Their common goal was to learn more about the emerging clinical and business model for medical laboratories known as “Clinical Lab 2.0.” A key objective of the workshop was to help those lab leaders in attendance develop strategic action plans for their own lab organizations, so as to take advantage of the insights coming from the vast information streams generated by their clinical laboratories. These services would be in support the evolving needs of health systems, hospitals physicians, and health insurers to more effectively provide integrated patient-centered clinical care.
Medical Laboratories Can Use Clinical Lab 2.0 as a Path to Adding Value
Clinical Lab 2.0 is the clinical and business model of the future for medical laboratories, assert the developers of this concept. “Clinical Lab 2.0 describes the attributes needed by all medical laboratories that want to succeed in a healthcare system organized to provide precision medicine, keep people out of hospitals, and where providers—including labs—are reimbursed based on the value they provide,” stated Khosrow Shotorbani, CEO of TriCore Reference Laboratories, one of the organizers of the Project Santa Fe Clinical Lab 2.0 Workshop.
“Clinical Lab 2.0 is the path medical labs will need to follow if they are to continue providing relevant lab testing services and generate the reimbursement necessary for them to maintain a high level of clinical excellence and financial stability going forward,” he added. “This is the next generation of medical laboratory organization and operation.”
Lab 1.0 Was Lab Clinical/Business Model for 50 Years
For more than 50 years, Clinical Lab 1.0 was the model for labs,” noted James Crawford, MD, PhD, Executive Director and Senior Vice President of Laboratory Services at Northwell Health Laboratories and an organizer of the Project Santa Fe Clinical Lab 2.0 Workshop. “Lab 1.0 is transactional, focusing on generating high quality analytical data on specimens received, but without assembling these data into integrative clinical care programs. In the simplest sense, Clinical Lab 1.0 focused on generating ever-greater numbers of specimens to drive down average cost-per-test, while maximizing revenue in a fee-for-service system.
This chart shows the attributes of Clinical Lab 1.0 and compares those to the attributes of Clinical Lab 2.0. Lab 1.0 is transactional and based on increasing test volume to lower costs and maximize fee-for-service revenue. Clinical Lab 2.0 is integrative in ways that add value to lab testing services.

“But fee-for-service payment is going away,” he said. “Increasingly, clinical laboratories will be paid based on the value they provide. This payment can be in the form of bundled reimbursement, as a per-member-per-month payment, or as a share of the budgeted payment made to a health system, an accountable care organization (ACO), or a multispecialty provider network. As these alternative forms of provider payment become dominant, to earn a fair share of reimbursement, all medical laboratories will need a clinical strategy to deliver lab testing services that measurably contribute to improved patient outcomes while reducing the overall cost of care. This requires looking at medical laboratories’ contribution to effective delivery of the full dollar of the healthcare spend, not just the three-cents-on-the-dollar representing laboratory testing.”
Innovators in Clinical Laboratory Industry Identify New Ways to Add Value
There are already a handful of innovative clinical laboratory organizations that have clinical experience in moving past the Lab 1.0 paradigm of reporting an accurate test result within the accepted turnaround time. Leaders within these labs are collaborating with physicians and frontline care givers specifically to help them better utilize lab tests in ways that directly improve the speed and accuracy of the overall diagnostic sequence, as well as achieving therapeutic optimization as rapidly as possible. These collaborations are tracking the improvement in patient outcomes while demonstrating how better use of lab tests can lower the total cost per episode of care.
During the Clinical Lab 2.0 workshop, case studies were presented demonstrating how clinical laboratory leaders are taking the first steps to practice Clinical Lab 2.0 so as to achieve added value with medical laboratory tests. The case studies included:
· A project to improve diagnosis and treatment of sepsis at Geisinger Health System.
· A project at Henry Ford Health to collaborate with physicians to more appropriately utilize lab tests and build consensus in support of a new lab test formulary.
· A multi-hospital initiative at Northwell Health to collaborate with physicians and nurses in the use of creating testing to make earlier, more accurate diagnoses of acute kidney injury during inpatient admissions, and better guide decisions to treat.
· A partnership involving TriCore Reference Laboratory and certain health insurers in New Mexico where the laboratory—using lab test data (some generated by emergency room testing) and other clinical data—alerts the insurers to women who are pregnant, thus allowing the insurers to provide timely guidance to the women’s care teams with the goal of improving prenatal care.
The Project Santa Fe Clinical Lab 2.0 Workshop convened on November 13-14 in Albuquerque, N.M. A broad spectrum of innovative professionals from the five Project Santa Fe member laboratories (above) were there to teach the lessons learned from their first successful efforts to collaborate with physicians and create added value from medical laboratory diagnostics. Other attendees included progressive lab leaders from several of the nation’s most prominent health systems, along with thought leaders from the IVD, lab software, and lab association sectors.

Project Santa Fe Workshop: A Well-Attended Lab ‘Think Tank’
Participants attending the Clinical Lab 2.0 workshop included hospital lab administrators, pathologists, and clinical laboratory industry executives. The importance of this workshop is reflected in the educational grants and financial support provided by leading in vitro diagnostics manufacturers, lab IT companies, and other lab industry vendors. The lab industry vendors included:
· Abbott Laboratories
· ARUP Laboratories
· Beckman Coulter
· DiaSorin
· MedSpeed
· Roche Diagnostics
· Siemens Healthineers
· Sysmex
Also providing educational grants and similar support were:
· American Clinical Laboratory Association
· CAP Today
· Centers for Disease Control and Prevention
· Mayo Medical Laboratories
· The Dark Report
Project Santa Fe was launched in 2016 by clinical lab leaders from five of the nation’s most respected integrated health systems:
· TriCore Reference Laboratories;
· Henry Ford Health;
· Geisinger Health;
· Kaiser Permanente Northern California; and,
· Northwell Health.
Described as a think-tank venture, the organizers are committed to implementing projects that demonstrate how lab tests can be used in ways that add value, and then publish the resulting projects, along with data about improved patient outcomes and reductions in healthcare costs, in peer-reviewed journals. Multi-institutional studies will be required to validate the findings and outcomes from the added-value clinical collaborations initiated at the different medical laboratory organizations participating in Project Santa Fe.
Another primary goal is to share the lessons learned from these innovative projects with other like-minded pathologists, lab administrators, and lab managers. In May, Project Santa Fe organizers led a one-day workshop to teach Clinical Lab 2.0 at the Executive War College on Laboratory and Pathology Management. The workshop in Albuquerque on November 13-14 was the second learning opportunity available to medical laboratory professionals. A November 2018 workshop is planned.

FDA is streamlining how new diagnostic tests are approved; encourages IVD companies to focus on ‘qualifying biomarkers’ in development of new cancer drugs
It is good news for the anatomic pathology profession that new insights into the human immune system are triggering not only a wave of new therapeutic drugs, but also the need for companion diagnostic tests that help physicians decide when it is appropriate to prescribe immunotherapy drugs.
Rapid advances in precision medicine, and the discovery that a patient’s own immune system can be used to suppress chronic disease, have motivated pharmaceutical companies to pursue new research into creating targeted therapies for cancer patients. These therapies are based on a patient’s physiological condition at the time of diagnosis. This is the very definition of precision medicine and it is changing how oncologists, anatomic pathologists, and medical laboratories diagnose and treat cancer and other chronic diseases.
Since immunotherapy drugs require companion diagnostic tests, in vitro diagnostic (IVD) developers and clinical laboratory and pathology group leaders understand the stake they have in pharma companies devoting more research to developing these types of drugs.
New cancer drugs combined with targeted therapies would directly impact the future of anatomic pathology and medical laboratory testing.
Targeted Therapies Cost Less, Work Better
Targeted therapies focus on the mechanisms driving the cancer, rather than on destroying the cancer itself. They are designed to treat cancers that have specific genetic signatures.
One such example of a targeted therapy is pembrolizumab (brand name: Keytruda), a humanized antibody that targets the programmed cell death 1 (PD-1) receptor. The injection drug was primarily designed to treat melanoma. However, the FDA recently expanded its approval of Keytruda to include treatment of tumors with certain genetic qualities, regardless of the tumor’s location in the body. It was the first time the FDA has expanded an existing approval.
In a Forbes article, David Shaywitz, MD, PhD, noted that pembrolizumab had “an unprecedented type of FDA approval … authorizing its use in a wide range of cancers.” Shaywitz is Chief Medical Officer of DNAnexus in Mountain View, Calif.; Visiting Scientist, Department of Biomedical Informatics at Harvard Medical School; and Adjunct Scholar, American Enterprise Institute.
Cancers with high mutational burdens respond to the therapy because they are more likely to have what Shaywitz calls “recognizable novel antigens called mutation-associated neoantigens, or MANAs.” Such cancers include melanomas, non-small cell lung cancer, some rare forms of colorectal cancers, and others.
Such therapies require genetic sequencing, and because sequencing is becoming faster and less expensive—as is the analysis of the sequencing—the information necessary to develop targeted therapies is becoming more accessible, which is part of what’s motivating pharma research.
Biomarkers and Traditional versus Modern Drug Testing and Development
At the same time pharma is developing new immunotherapies, the FDA is recognizing the benefit of faster approvals. In an FDA Voice blog post, Janet Woodcock, MD, Director of the Center for Drug Evaluation and Research (CDER) at the FDA, wrote, “In the past three years alone, [we have] approved more than 25 new drugs that benefit patients with specific genetic characteristics … and we have approved many more new uses—also based on specific genetic characteristics—for drugs already on the market.”
In his Forbes article, Shaywitz notes that pembrolizumab’s development foreshadows a “More general trend in the industry,” where the traditional phases of drug testing and development in oncology are becoming less clear and distinct.
Along with the changes to drug development and approval that precision medicine is bringing about, there are also likely to be changes in how cancer patients are tested. For one thing, biomarkers are critical for precision medicine.
However, pharmaceutical companies have not always favored using biomarkers. According to Shaywitz, “In general, commercial teams tend not to favor biomarkers and seek to avoid them wherever possible.” And that, “All things being equal, a doctor would prefer to prescribe a drug immediately, without waiting for a test to be ordered and the results received and interpreted.”
In July, just weeks after expanding its approval for Keytruda, the FDA approved a Thermo Fisher Scientific test called the Oncomine Dx Target Test. A Wired article describes it as “the first next-generation-sequencing-based test” and notes that it “takes a tiny amount of tumor tissue and reports on alterations to 23 different genes.”
Thermo Fisher’s Oncomine DX Target Test (above) is the first multi-drug next-generation sequencing test approved by the FDA. The test is a companion diagnostic for lung-cancer drugs made by Novartis and Pfizer. (Caption and photo copyright: Thermo Fisher Scientific.)
Unlike pembrolizumab, however, the Oncomine Dx Target Test did not enjoy fast-track approval. As Wired reported, “Getting the FDA’s approval took nearly two years and 220,000 pages of data,” in large part because it was the first test to include multiple genes and multiple drugs. Thus, according to Joydeep Goswami, PhD, President of Clinical Next Generation Sequencing at Thermo Fisher, “That put the technology under extraordinary scrutiny.”
FDA Encouraging Use of Biomarkers in Precision Medicine Therapies
The FDA, however, is taking steps to make that process easier. Woodcock noted in her FDA Voice blog post that the agency is actively encouraging drug developers to “use strategies based on biomarkers.” She added that the FDA currently “works with stakeholders and scientific consortia in qualifying biomarkers that can be used in the development of many drugs.”
Additionally, in a column he penned for Wired, Robert M. Califf, MD, former Commissioner of the FDA, states that the organization has “begun to lay out a flexible roadmap for regulatory approval.” He notes, “Given the complexity of NGS [next-generation-sequencing] technology, test developers need assurance as well, and we’ve tried to reduce uncertainty in the process.”
Regulations that assist IVD developers create viable diagnostics, while ensuring the tests are accurate and valid, will be nearly as important in the age of precision medicine as the therapies themselves.
All of these developmental and regulatory changes will impact the work done by pathologists and medical laboratories. And since precision medicine means finding the right drug for the individual patient, then monitoring its progress, all of the necessary tests will be conducted by clinical laboratories.
Faster approvals for these new drugs and tests will likely mean steep learning curves for pathologists. But if the streamlined regulation process being considered by the FDA works, new immunoassay tests and targeted therapies could mean improved outcomes for cancer patients.

Report states IVD companies are focusing on core lab, seeking China FDA approval, and targeting urgent care
Several of the same powerful trends reshaping healthcare and clinical laboratory services are having equally significant influence on in vitro diagnostics (IVD) manufacturers. In particular, the consolidation of hospitals and physicians, as well as the emergence of new sites of service—such as urgent care centers and retail clinics—are motivating IVD companies to tailor new diagnostic systems to the unique needs of these entities.
Kalorama, a division of MarketResearch.com, has released its list of Top-Trends that will affect IVD developers in 2017. IVDs are at the heart of the medical laboratory industry. Thus, these reports are critical to keeping clinical laboratory managers and pathology groups informed on anything that could affect the production, voracity, and availability of diagnostic testing.
