Prescription/result interpretation

There are times when the name of the drug on the prescription bottle does not match the drug identified on the results report. This may be because the bottle lists a trade name instead of the drug name. Or it may be that the laboratory may analyze for the metabolites of a drug, not the parent drug itself. Often in urine drug testing we look for drug metabolites, or what the body breaks the drug down into as opposed to analysis of the parent drug. The parent drug is either not present in the urine, or is present in such low amounts for such a short amount of time, that testing for it is not practical.

If you have questions regarding whether the results of your drug testing match the prescription medication taken by the patient/donor, please contact a scientist at the laboratory. We will be happy to assist you.
