New Blood Test for Alzheimer’s Is 91% Accurate, Study Finds
A groundbreaking new blood test announced this week is capable of diagnosing Alzheimer’s disease with 91 percent accuracy—opening the way to routine testing for the condition, similar to that for cholesterol or prostate cancer.
The breakthrough, unveiled by Swedish researchers at the Alzheimer’s Association International Conference in Philadelphia and published in JAMA, revealed that the new blood tests are far more accurate than family doctors and even specialists.
Traditionally, Alzheimer’s diagnosis has depended on a specialist making a finding followed by more invasive methods like spinal taps and brain scans.
