RIDASCREEN® Ethinylöstradiol is a competitive enzyme immunoassay for the quantitative analysis of ethinylestradiol residues in urine, meat and plasma.
Ethinylestradiol is a synthetic sexual hormone which is, like all other natural or synthetic steroid hormones, prohibited for use as resource in fattening in the European Community since 1988.
