Mayo Clinic researchers validate blood test to diagnose Alzheimer’s disease in outpatient memory clinics
“Our study found that blood testing affirmed the diagnosis of Alzheimer’s disease with 95% sensitivity and 82% specificity,” says corresponding author Gregg Day, M.D., a Mayo Clinic neurologist, dementia specialist and clinical researcher. “When performed in the outpatient clinical setting, this is similar to the accuracy of cerebrospinal fluid biomarkers of the disease and is much more convenient and cost-effective.”
