Blood Tests Emerging as Key Tool in Alzheimer's Diagnosis and Care

The Alzheimer’s Association has issued new guidelines suggesting that blood tests with over 90% sensitivity and 75-90% specificity can be used to help diagnose Alzheimer’s disease, potentially replacing more invasive tests like PET scans, especially in cases of cognitive impairment, though they should complement full clinical evaluations. This move aims to improve access to diagnosis, particularly in rural areas, and supports the ongoing development of blood-based diagnostic tools, which are increasingly being integrated into treatment protocols.
