FDA approves first blood test technology for diagnosing Alzheimer's disease.

The US Food and Drug Administration announced on Friday that it has approved Fujirebio Diagnostics' blood testing technology "Lumipulse" for diagnosing Alzheimer's disease, making it the first approved blood testing device for Alzheimer's disease. Blood testing can accelerate the diagnosis of the disease and make it easier for more people to access treatment. Other methods for detecting Alzheimer's disease include spinal tap, which requires an invasive procedure to collect spinal fluid, or expensive PET brain scans that may not be covered by health insurance companies.
