Blood tests for Alzheimer's diagnosis were 91% accurate in new study

Category: Health

New blood tests show promise for faster and more accurate diagnosis of Alzheimer's disease, outperforming traditional methods. A study involving 1,200 patients revealed blood tests had a 91% accuracy rate compared to 61% for primary care doctors and 73% for specialists. The tests measure biomarkers like p-tau217, which correlate with amyloid plaque buildup. While these tests are not yet widely used or FDA-approved, they could significantly aid primary care physicians in diagnosing memory issues.
