Drug Detection Time for Urine Drug Testing
Detection time is the number of days after intake of a drug that an individual would be expected to excrete detectable levels of drug metabolite in urine. Variances in these time limits due to such factors as dosage, frequency of use, liquid consumption, and individual metabolic characteristics are to be expected. The detection times below allow for these variances and are based on current literature and procedures used in our lab.
