Drawing Closer: Alzheimer’s Blood Test for Primary Care

In today’s JAMA Neurology, researchers led by Oskar Hansson, Lund University, Sweden, report how a fully automated immunoassay for plasma Aβ performed when they put it through its paces. Roche Diagnostic’s Elecsys system predicted Aβ-positive individuals with about 80 percent accuracy. That number improved by 5 percent when the researchers took ApoE genotype into consideration. Alzforum first reported on this data when Hansson presented it at AAIC in 2018 (Aug 2018 conference news [1]). Since then, first author Sebastian Palmqvist and colleagues have tested samples in a validation cohort in Germany. Here the test was more accurate, at 86 percent. “I think we are not that far away from a blood-based biomarker that can be implemented in primary care to improve diagnostics of AD,” Hansson told Alzforum.
