Description

Jaiyeoba-Ojigho and team reviewed accuracy studies of blood tests for early Alzheimer's disease. Such tests are an appealing alternative to costly brain scans and needle-based spinal fluid sampling. Searching five databases for studies from 2010 to March 2026 under standard review rules left just six qualifying accuracy studies.

Phosphorylated tau markers did most consistently, with p-tau181 and p-tau217 reaching areas under the curve up to 0.93 for detecting Alzheimer's pathology in the included studies. The glial marker GFAP also did strongly at up to 0.87, while amyloid ratios ranged widely from 0.69 to 0.94 across different commercial assays tested. Neurofilament light chain topped out at 0.79 and predicted progression better than early presence of disease in the review's synthesis. Combinations, especially adding APOE genetic status, beat single markers, reaching 0.92 in the best-performing panels.
