Immunochemical techniques for anabolic androgenic steroid: matrix effects study for food supplements

Anabolic androgenic steroid contaminations in food supplements are common, and their consumption may lead to positive doping results. One of such anabolic steroid is mesterolone selected as an analyte for the present study. Some contaminated supplements cannot be detected by traditional methods due to the matrix effect. Two variants of indirect competitive immunochemical method—an enzyme-linked immunosorbent assay and an immunochromatographic...
