Introduction:

Intended use:
RIDASCREEN® 19-Nortestosteron is a competitive enzyme immunoassay for the
quantitative analysis of of 19-nortestosterone in urine.

General information:
The anabolic effects of 19-Nortestosterone are comparable to those of testosterone,
but with less androgenic effects.
In Germany, 19-Nortestosterone-decanoate 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.
