RIDASCREEN® 19-Nortestosteron is a competitive enzyme immunoassay for the quantitative analysis of 19-Nortestosterone in urine.
All reagents required for the enzyme immunoassay - including standards - are contained in the test kit.
For in vitro use only.
General Information:
The anabolic effects of 19-Nortestosterone are comparable to those of testosterone, but with less androgenic effects. In Germany, 19-Nortestosteronedecanoate and -laureate are permitted for veterinary use. However, the illegal use of 19-Nortestosterone as doping agents in high performance sports or horse sports are far more common. Some years ago the increasing application of illegal cocktails as a fattening resource in calf fattening was reported. Those cocktails usually contained 19-Nortestosterone-ester.
