Test Overview

Red blood cell (RBC, erythrocyte) metal analysis gives a current snapshot of functional mineral status as well as toxic metals. Since it measures the mineral content inside blood cells, it gives a better indication of the minerals that the body is actually absorbing and utilizing. Since the average lifetime of RBC is about 4 months, the results reflect an average over the past 4 months [FDM].
