FDA Clears First Blood Test to Reliably Predict Alzheimer’s Disease

  • On Friday, federal health authorities approved the first blood test in the United States designed to aid in diagnosing Alzheimer's disease.
  • This clearance follows a need for less invasive, reliable detection methods since existing ones required spinal fluid or radioactive imaging.
  • The test by Lumipulse measures protein ratios linked to brain amyloid plaques in blood samples from patients 55 or older showing Alzheimer's symptoms.
  • Lumipulse's test showed over 91% success in prior trials and Dr. Michelle Tarver noted nearly 7 million Americans live with Alzheimer's, expected to reach nearly 13 million.
  • This FDA approval may improve diagnosis accessibility, aid treatment decisions, and support expanding use of drugs that modestly slow Alzheimer's progression.
