The non-compliance rates for resorcylic acid lactones
(hormonally active compounds produced by fungi or man-made) and contaminants such as metals and mycotoxins (toxins produced by fungi) were higher than for other groups of substances, but slightly down on the previous report.
Instrumental analysis revealed estrone but no significant levels of resorcylic acid lactones or trenbolone metabolites.
2], Tb-17[alpha], Tb-17[beta], the six resorcylic acid lactones ([alpha]-zearalenol, [beta]-zearalenol, [alpha]-zearalanol, [beta]-zearalanol, zearalenone, zearalanone), and MGA] were assayed using both the E-SCREEN and the A-SCREEN assays.
2], 99% for testosterone, 103% for Tb-17[beta], 100% for Tb-17[beta], and between 95% and 101% for six resorcylic acid lactones.
