A simple blood test has been shown to detect Alzheimer’s disease in routine health care settings with up to 90% accuracy, according to Swedish researchers.The findings were presented at the Alzheimer’s Association International Conference in Philadelphia on Sunday.The test works by measuring the levels of Plasma Phospho-Tau217, a biomarker that is linked to the presence of Alzheimer’s pathology in the brain.BLOOD TESTS FOR ALZHEIMER’S MAY BE COMING TO YOUR DOCTOR’S OFFICE: WHAT TO KNOWIt has been shown to detect the disease even before the person begins experiencing symptoms, researchers say.”The tested blood test can detect Alzheimer’s disease with high accuracy even in real-life settings in primary care,” said study author Oskar Hansson, M.D., head of the Clinical Memory Research Unit at Lund University, Sweden, in an email to Fox News Digital.

In the most recent study — also published in the journal JAMA — 1,213 people who were experiencing mild memory loss were evaluated by either primary care doctors or memory specialists. MAYO CLINIC FINDS NEW TYPE OF MEMORY LOSS THAT’S OFTEN MISTAKEN FOR ALZHEIMER’SThe patients then underwent both the blood test and cerebrospinal fluid tests, and researchers compared the results.”Primary care doctors’ accuracy in identifying Alzheimer’s disease was 61%, while specialist physicians were correct 73% of the time,” study author Sebastian Palmqvist, associate professor of neurology at Lund University, stated in a press release.By comparison, the blood test had an accuracy of 90%. It is currently difficult for primary care physicians to diagnose Alzheimer’s disease because of a lack of adequate tools, according to researchers.

The blood test could help to reduce the need for more advanced and expensive methods, like PET scans and cerebrospinal tests.
