ASSAY METHODS AND DEVICES THEREFOR

摘要

A method for determining the concentration of an analyte such as estrone-3-glucuronide in a urine sample, wherein the method is rendered less dependent on biological volume variability in the original sample source by determining the concentration of an androgen or a metabolite thereof, especially testosterone-17 beta -glucuronide, in the same original body fluid sample source and comparing the two concentration values so determined.
