Japanese testing reagent maker Fujirebio Inc. announced on Tuesday that it has applied to the Japanese Health, Labor and Welfare Ministry for approval to manufacture and sell a blood test kit to assist in diagnosing Alzheimer's disease. The kit is expected to reduce the burden on patients compared to conventional tests, and lead to earlier diagnosis.
Alzheimer's disease is thought to occur when abnormal proteins called "amyloid beta" and "tau" accumulate in the brain, damaging nerve cells and leading to cognitive decline. The test kit measures the concentration of these proteins in plasma, according to the company.
Currently, the procedures for diagnosis include expensive imaging tests like "amyloid PET" scans and invasive lumbar puncture procedures to test cerebrospinal fluid. If approved, Fujirebio's test would only require a blood draw, thus reducing the burden on patients and believed to make testing more accessible.
