Drug Detection Times in Urine
The drug detection time is the time from the last dose of the drug until a negative screening result is obtained using the cut-off levels in the above table. Detection times vary with different drugs and different individuals and according to the amount and frequency of drug taken. It is important to note that whilst a drug may be excreted in the urine for a significant time, it may not reach the threshold required for a positive result. The following table lists the average detection times for a number of drugs.
