Scientists at Northwestern University have developed a rapid PCR test that can diagnose hepatitis C in about 15 minutes using whole blood samples. Adapted from a COVID-19 detection system and built on the DASH rapid PCR platform, the test aims to enable same-day treatment and bolster global efforts to eliminate the virus, with early evaluations showing accuracy comparable to existing commercial platforms.
The US Food and Drug Administration has approved a new blood test to assist in diagnosing Alzheimer’s disease. Produced by Roche, the test measures levels of a phosphorylated tau protein in the blood. This development aims to enable earlier screening and access to treatments like monoclonal antibodies.

Scientists at the University of East Anglia and Oxford BioDynamics say a blood test using 3D genomics identified myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) with 96% accuracy in a small, retrospective study published in the Journal of Translational Medicine. The team adds the approach may also inform diagnosis of some long Covid cases, though further validation is needed.
