Alzheimer's blood tests edge closer to routine clinical use

Original: Alzheimer’s blood tests are moving closer to routine clinical use. Biomarkers such as p-tau217 can help identify Alzheim

Blood-based biomarkers such as p-tau217 are moving toward routine clinical use for detecting Alzheimer's-related brain changes earlier than current methods allow. The tests could significantly reduce reliance on expensive PET scans and invasive spinal-fluid procedures, making diagnosis more accessible. Commenters in medical communities are highlighting this as a practical step forward in dementia care.

Why now: New momentum around simpler, cheaper Alzheimer's diagnosis is drawing attention from clinicians and patients alike.
