| | Nandrolone Positive Drug Tests — What Do They Mean? |
 | | It would appear, however, that in the case of a nandrolone ester, because its excretion after some weeks does not follow a simple first order kinetics, very low levels of the compound and its metabolites are present in the body (and subsequently in the urine) many months after it is last injected. |
 | | It’s been adequately shown that norandrosterone and noretiocholanolone, and likely nandrolone itself, are endogenous hormones in man. Thus, as we have seen, it’s the amount of hormone metabolites found in the urine, rather than the presence in the urine, that forms the basis of a positive doping test. |
 | | The presence of nandrolone in hair could be used to substantiate the exogenous use of nandrolone since endogenous nandrolone levels exist as an intermediate product that is converted in whole to it’s metabolites including NA and NE, and as such are too low to be detected in serum, urine or hair. |
