Pathologists in medical laboratories creating laboratory-developed tests (LDTs) should be aware that some in the scientific community want more transparency about technology and methods
Developers of clinical laboratory tests and medical diagnostic technologies might soon be feeling the pressure to increase their push for transparency and standards that ultimately would make replication easier.
That’s thanks to a review project’s inability to reproduce results from three of five high-profile cancer studies.
The review project is called the Reproducibility Project: Cancer Biology and is a collaboration between network provider Science Exchange of Palo Alto, Calif., and the Center for Open Science in Charlottesville, Va. They attempted to independently replicate selected results from high-profile cancer biology papers in an open fashion. (more…)

Use of these new technologies creates opportunities for clinical laboratories and pathologists to add more value when collaborating with physicians to advance patient care
Ongoing improvements in point-of-care testing are encouraging one major academic medical center to apply this mode of testing to the diagnosis of hospital-acquired infections (HAIs). This development should be of interest to clinical laboratory professionals and pathologists, since it has the potential to create a different way to identify patients with HAIs than medical lab tests done in the central laboratory.
Massachusetts General Hospital (MGH), Harvard Medical School’s (HMS’) largest teaching hospital, has developed a prototype diagnostic system that works with doctors’ smartphones or mobile computers. The hand-held system can identify pathogens responsible for specific healthcare-acquired infections (HAIs) at the point of care within two hours, according to an MGH statement.
The researchers noted that 600,000 patients develop HAIs each year, 10% of which die, and that costs related to HAIs can reach $100 to $150 billion per year. However, as Dark Daily reported, the Centers for Medicare and Medicaid Services (CMS) does not reimburse hospitals for certain HAIs. (See Dark Daily, “Consumer Reports Ranks Smaller and Non-Teaching Hospitals Highest in Infection Prevention,” October, 30, 2015.) Thus, the critical need to identify from where the infection originated, which generates a significant proportion of samples tested at the clinical laboratories of the nation’s hospitals and health systems.
Therefore, pathologists and medical laboratory scientists will understand that shifting some of that specimen volume to point-of-care testing will change the overall economics of hospital laboratories.
Smartphone-based Genetic Test for HIAs
The MGH research team created a way to do accurate genetic testing in a simple device powered by a system they call Polarization Anisotropy Diagnostics (PAD). The system measures changes in fluorescence anisotropy through a detection probe’s recognition of bacterial nucleic acid, reported Medscape Medical News. More than 35 probes for detecting bacterial species and virulence factors are available.
Optical test cubes are placed on an electronic base station that transmits data to a smartphone or computer, where results are displayed. “In a pilot clinical test, PAD accuracy was comparable to that of bacterial culture. In contrast to the culture, the PAD assay was fast (under two hours), multiplexed, and cost effective (under $2 per assay), wrote the MGH researchers in the journal Science Advances. (more…)

Federal agency hopes its open-source precisionFDA web portal will aid in development of laboratory-developed tests and inform regulatory decision-making
One recent initiative launched by the Food and Drug Administration (FDA) to foster the greater sharing of genetic information may be of some value to pathologists and clinical laboratory scientists who are developing laboratory-developed tests (LDTs) that incorporate molecular and genetic technologies.
The FDA unveiled an open-source platform for community sharing of genetic information. It is called precisionFDA, and the FDA describes its new web platform as an “online, cloud-based portal that will allow scientist from industry, academia, government, and other partners to come together to foster innovation and develop the science” of next-generation DNA sequencing processing.

Goal is to enable gene sequencing data to reside in EMRs, which would provide pathologists and clinical lab professionals with an opportunity to add value
More federal grant money is available to speed up research designed to make it possible to incorporate genome information into the electronic medical record (EMR). This is a development that can have both positive and negative consequences for clinical laboratories and anatomic pathology groups.
The National Institutes of Health (NIH) is awarding more than $48.6 million in grants to researchers seeking to better understand the clinical implications of genomic information and determine the best ways to deliver news to patients when their genetic data indicates they may be predisposed to certain diseases or medical conditions.
The grants are administered by the National Human Genome Research Institute (NHGRI) and represent the third phase of the Electronic Medical Records and Genomics (eMERGE) program. This is a national consortium working to move genomics research closer to clinical application by identifying the potential medical effects of rare genomic variants in about 100 clinically-relevant genes.

Example is a big data-based study involving Optum and Mayo Clinic that indicates diabetes management can be too aggressive for some patients
Mayo Clinic has tapped Optum Labs’ huge data set to fuel research suggesting diabetes management can be too aggressive among those diabetics who don’t have problems controlling their glucose level. Optum Labs’ data is also being mined to investigate dozens of research initiatives, including a major fight against Alzheimer’s disease. These projects provide a glimpse into the growing role of big data in healthcare.
Because more than 70% of a typical patient’s permanent medical record consists of clinical laboratory test data, pathologists and medical laboratory scientists have a stake in the growth of big-data analytics, which are a core component in healthcare’s journey toward personalized medicine. (more…)
