Fujirebio Diagnostics asked the U.S. Food and Drug Administration (FDA) to approve its Alzheimer’s disease diagnostic blood test,  Lumipulse G pTau 217/β [beta]-Amyloid 1-42 Plasma Ratio. If approved, the test would be the first commercially available blood-based in vitro test in the U.S. to aid in diagnosing…

The U.S. Food and Drug Administration (FDA) has granted breakthrough device designation to Quanterix’s experimental blood test measuring p-Tau 217, the protein that builds up as toxic tangles in the brains of people with Alzheimer’s disease. The test, Simoa p-Tau 217, has the potential to help doctors diagnose…

A commercially available blood test, sold by ALZpath, can identify with high accuracy Alzheimer’s disease patients who are likely to be eligible for new treatments, a study suggests. By detecting a version of the tau protein in a blood sample, the “ALZpath pTau217 test can help healthcare providers…

A novel technique that detects DNA from dead nerve cells in the blood may help diagnose Alzheimer’s disease and predict its development with a five-year window among people with mild cognitive impairment, a new study showed. The work was led by scientists at Resonant, a subsidiary of…

The PrecivityAD blood test from C2N Diagnostics significantly influences clinicians’ decisions about whether to treat people with cognitive impairments for Alzheimer’s disease. C2N, which sponsored the recent study, believes those findings offer robust real-world evidence that blood biomarker testing in the clinic helps to guide treatment decisions…

Quest Diagnostics has launched a consumer-initiated blood test for adults in the U.S. that assesses Alzheimer’s disease risk by measuring levels of certain forms of the amyloid beta protein, a known marker of the neurodegenerative disorder. Called AD-Detect, the test is now the first of its kind…

A blood test that checks for the abnormal activation of star-shaped cells in the brain called astrocytes may be able to identify people who are more likely to develop Alzheimer’s disease, a new study suggests. “Our study argues that testing for the presence of brain amyloid along with blood…

C2N Diagnostics has developed a new assay that precisely measures blood levels of four forms of tau, a protein involved in the brain changes observed in Alzheimer’s disease. Called the plasma tau multianalyte assay (p-tau MAA), the test is intended to be used for research purposes only and…

Brown University is establishing the Center for Alzheimer’s Disease Research to build a world-class research program that is focused on the early detection and treatment of Alzheimer’s disease and related disorders. The center is made possible by separate gifts of $25 million and $5 million from donors who wish…

A specific form of the tau protein, called phosphorylated-tau-217 or p-tau217, may function as a blood biomarker of Alzheimer’s disease, allow the development of blood tests to accurately diagnose the disease at earlier stages. These are the findings of three studies presented during the recent Alzheimer’s Association International Conference (AAIC)…
