Immunoassays for the Determination of Growth Stimulator Residues in Food

Novel analytical methods for the determination of steroid hormones in edible matrices

“…Recently, this was also proven for urine of pregnant cows (in the ␣ form) [118] and of bulls due to stress prior to slaughter [M. O'Keeffe, G. Kennedey, personal communication]. In 1989, Belgian and Dutch researchers found that NT (in the ␤ form) and norandrostenedione are also present in the urine and edible parts of the intact male pig [119][120][121]. Several researches demonstrated that eating organs of intact male pigs might lead to false positive results in doping analysis for sportsmen [122][123][124][125][126][127].…”

Forensic science

“…The prediction of GC relative retention times of anabolic steroids was performed by a quantitative structure-retention relationship (QSRR) and multiple linear regression analysis study (347). The illegal use of anabolic steroids and their control in Belgium has been discussed (348).…”
