Alzheimer's Disease vs Control: tau-total (Plasma and Serum)
Meta-analysis Results: A handful of studies have quantified total tau levels in the plasma of people with Alzheimer’s disease. Meta-analysis of eight eligible comparisons shows a significant increase in total tau in AD (effect size = 1.788, p = 0.00550); however, there was considerable variability between studies and possibly between methods.
