ESMO data buttress MCED test potential for the undiagnosed
One of the latest studies reported at ESMO showed that an MCED test could detect a cancer signal in 1.4% of 6,621 people ages 50 years and over who were not known to have cancer, and that cancer was later confirmed in 38% of those who received a positive MCED test.

Video telemed diagnoses are accurate: Mayo Clinic study
In a 90-day period from late March to late June 2020, nearly 2400 patients who underwent a video telemedicine consultation had their diagnosis match an in-person reference standard diagnosis in 86.9% of cases.

Antigen tests accurately detect COVID-19 variants in study
The research, led by a team at the University of Washington in cooperation with University of Nevada, concluded that two rapid antigen tests -- i.e., SCoV-2 Ag Detect Rapid Self-Test (InBios International) and Binax NOW COVID-19 Ag Card (Abbott Laboratories) -- had consistent analytical and clinical accuracy across three phases of circulating forms of the SARS-CoV-2 variants.

Genetic risk score may reduce invasive prostate biopsies
In research published Thursday in the British Journal of Cancer, the U.K.-based researchers calculated genetic risk for prostate cancer by leveraging more than 250 known genetic variants that are commonly linked to the disease. These genetic variants were all combined to form a single genetic risk score that could then be used to assess an individual's genetic risk of developing prostate cancer.

CRISPR test leverages quantitative, colorimetric readout
Today's prevalent biomarker diagnostic tools that are based on RNA and DNA require controlled temperatures and involve a fairly complicated multi-tiered process. This latest test, dubbed CrisprZyme, can be used at room temperatures and is comparatively easy to use, leading to quicker and easier diagnoses.

CAP issues guideline to improve immunotherapy treatment
The CAP guideline is evidence-based and joins a small number of testing methods based on both the methodology and the status of the biomarker -- i.e., microsatellite testing and deficient mismatch repair process assessment. This stands in contrast to previous guidelines that focused on the cancer type or tumor origin.

AI algorithm improves accuracy of at-home COVID-19 tests
Researchers out of Imperial College London in the U.K. have recently developed an artificial intelligence (AI) algorithm that can take much of the guesswork out of analyzing our home-use lateral flow immunoassays (LFIAs). For people whose lives could be impacted by either false-negative or false-positive results in their home COVID-19 tests, the potential for more accurate readings of LFIAs would be a welcome development.
