The sample size of 14 yielded a power of more than.99 to detect the difference between positive and negative samples. Chemical structures of antidepressants like sertraline have some similarity to diazepam and may lead to a false positive result for benzodiazepines (table 1).6,8 there may be variability in which

If Your Lab Uses A Higher Cutoff, More False Negative Results May Occur, Whereas A Low Cutoff Will Have More False Positives.

Falsely negative is that a dose may not be of a sufficient concentration to reach the detection threshold level in the urine. Although the metabolites of naloxone hydrochloride are similar in structure to oxymorphone and are. Our laboratory uses the synchron enzyme.

Urine drug screening can detect cases of drug abuse, promote workplace safety, and monitor drugtherapy compliance. Confirmatory testing is essential to distinguish a true negative from a false negative.
