"Revolutionary Blood Tests Set to Transform Alzheimer's Diagnosis"

Blood tests for Alzheimer's are still a couple of years away from becoming an everyday diagnostic tool, according to medical experts and company executives. While several blood tests for Alzheimer's are in development, none have been established as accurate, approved by regulators, or reimbursed by insurers. Currently, Alzheimer's diagnosis relies on cognitive assessment and invasive tests like lumbar punctures or expensive PET brain scans. The need for blood tests has become more urgent since the FDA approved the Alzheimer's drug Leqembi, and researchers are working to identify the right combination of biomarkers in the blood to diagnose the disease. Labcorp and Quest Diagnostics have launched blood tests, but caution is advised as more information is needed. Accurate blood tests are expected to help identify which dementia patients have Alzheimer's, potentially changing the field of Alzheimer's care.
