A blood marker for detecting Alzheimer's disease tested
An international team with Spanish participation has analysed the usefulness of a blood biomarker - the p-tau217 protein - for detecting Alzheimer's disease in 1,767 patients. According to the authors, who publish the results in the journal Nature Medicine, the test has detected the disease with high reliability in four hospital cohorts, as well as in a primary care cohort. They add that it is an assay that can be easily implemented in clinical laboratories and is already routinely used in some centres in Spain.
