A positive hair test for Nor-Fentanyl indicates the presence of a metabolite associated with fentanyl, a potent synthetic opioid. This suggests that the individual has likely used fentanyl or related substances within a timeframe that corresponds to hair growth, typically several weeks to months prior to the test. Such results may have implications for legal, medical, or employment situations, depending on the context of the testing. It's important to interpret these results in conjunction with other clinical information and testing methods.
