New Alzheimer's Blood Test 'Most Accurate'
Ewen Callaway, Nature News
A new blood test diagnoses Alzheimer's disease by sensing molecules produced by the immune systems of people with the neurodegenerative condition.
So far, the test has been applied to just a small number of blood samples, but if proven on a larger scale, the assay could help diagnose Alzheimer's disease in combination with other tests, says Thomas Kodadek, a professor of chemistry at the Scripps Research Institute in Jupiter, Florida. It could also be used to identify patients for trials of experimental Alzheimer's drugs, he adds. His team published its results online today in Cell.
