AAIC: Finger prick blood test could detect Alzheimer's

A finger prick blood test shows promise in the ability to detect Alzheimer’s disease, according to research reported for the first time today at the Alzheimer’s Association International Conference (AAIC) 2023.

The blood test was more than 80% accurate in identifying Alzheimer’s-related changes - significantly better than doctors in the study who did not have access to the test.

"These findings are timely and important with the approvals of Alzheimer’s treatments targeting amyloid-beta, where confirmation of amyloid buildup and biomarker monitoring are required to receive treatment"Advances in technology and practice reported for the first time at the conference demonstrate the simplicity, transportability and diagnostic value of blood-based biomarkers for Alzheimer’s, including the future potential for at-home testing by a patient or a family member.
