A prototype heart-failure screening device that measures levels of two biomarkers for heart failure in as little as 15 minutes from a drop of saliva is being presented at the American Chemical Society (ACS) hybrid fall meeting, which is being held virtually and in person in Denver August 18-22.

Biogen Inc. (Nasdaq: BIIB), Beckman Coulter, Inc. and Fujirebio announced a collaboration to potentially identify and develop blood-based biomarkers for tau pathology in the brain and to potentially clinically advance and potentially commercialize new tests for tau pathology in Alzheimer’s disease (AD). The development of tau-specific blood-based biomarkers that can measure a patient’s tau burden could provide critical insights into the underlying pathological processes of AD and may help advance the development of a new generation of therapies impacting tau pathology.

A workgroup convened by the Alzheimer’s Association has published revised criteria for the diagnosis and staging of Alzheimer’s disease that are based on the biology of the disease and reflect recent advancements in Alzheimer’s research, diagnostics and treatment. The 2024 update includes an updated biomarker classification system that includes blood-based biomarkers (BBM) and a revised disease staging system.

AmoyDx, a China-based innovative molecular diagnostics company, and Servier, an independent international pharmaceutical group, announced today they have entered into a strategic partnership to develop a companion diagnostic test (CDx) in China that detects Isocitrate Dehydrogenase (IDH) 1&2 gene mutations. This test will be developed for vorasidenib, Servier’s investigational dual inhibitor of mutant IDH1 and mutant IDH2 enzymes, for Chinese patients with diffuse IDH-mutant glioma (LGG).

With the help of proteomic profiling and machine learning, an international team led by investigators in the UK and Germany has identified a handful of blood plasma proteins associated with subsequent Parkinson's disease development, pointing to the possibility of developing blood-based biomarkers for the progressive neurodegenerative condition.

Danaher Corporation (NYSE: DHR), a global science and technology innovator ("Danaher"), today launched a collaboration with Johns Hopkins University aiming to develop new methods for diagnosing mild TBI. As part of the Danaher Beacons program, researchers at Johns Hopkins University will leverage technology from Beckman Coulter Diagnostics, a Danaher subsidiary and leader in clinical diagnostics, to potentially establish correlations between a new biomarker panel and clinical outcomes.

QuidelOrtho announced Wednesday that it has received approval from Health Canada to market the firm's Triage PLGF test. The test detects a biomarker that can indicate the likelihood of a pregnant person developing preterm preeclampsia.

An analysis conducted by an international research team has identified 13 biomarkers that may improve the accuracy of predicting the risk of cardiovascular disease (CVD) in people with type 2 diabetes.

The immunoassay method involves the widest range of items among all fields of medical detection; with the development of biomedical research, especially genomics and post-genomics results (high-resolution two-dimensional electrophoresis combined with mass spectrometry) which highly promote the research on disease-related markers, more and more items will be detected via immunoassay in the medical practice.

Two recent Parkinson’s announcements suggest a new biomarker test panel coming, as well as cell culture systems for studying Parkinson’s in the laboratory.
