Intended use:
RIDASCREEN® DES is a competitive enzyme immunoassay for the quantitative analysis of diethylstilbestrol (DES) in urine, bile, muscle and feces.

General information:
Diethylstilbestrol and Hexestrol are substances of the group of stilbenes, which are very efficient anabolic steroids, combined with a strong estrogenic activity. DES is banned as fattening adjuvants in the EU and therefore Maximum Residue Performance Limits (MRPLs) are set for the particular matrices and methods.
