FDA clears Indiana's first Alzheimer's blood test
The FDA has cleared the first blood test for Alzheimer's disease, a breakthrough developed with research from Indiana University School of Medicine. This test offers a less invasive and more accessible method for diagnosis. The blood test, which is over 90% accurate, detects amyloid plaques in the brain by measuring the ratio of two proteins. It is available to people 55 and older exhibiting Alzheimer's symptoms and is ordered by a physician. This new test, developed with the help of IU School of Medicine researchers, could lead to earlier diagnoses and broader participation in clinical trials. It offers an alternative to more invasive and expensive methods like PET scans.
