    Introduction:

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

    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.
