A new blood test for Alzheimer’s could make an incredible diagnostic 30 years before symptoms begin, feat a reality.
A tiny drop of blood could be enough to predict the onset of Alzheimer’s, in this new blood test. It was accurate in 90% of patients tested.
One of the researchers, Koichi Tanaka from the Shimadzu Corporation in Japan, said:
“From a tiny blood sample, our method can measure several amyloid-related proteins, even though their concentration is extremely low. We found that the ratio of these proteins was an accurate surrogate for brain amyloid burden.”
