Drug metabolites begin appearing in urine a couple of hours after a substance is taken. These metabolites can be detectable in a urine sample for several days and up to 30 days after use.
Whether using a dip or cup screening test, urine presents the widest range of parameters for drug screening, and is often the first matrix to feature new parameters.
With best practice procedures in place, urine screening is a swift and reliable method of screening for recent drugs of abuse activity.
If a test shows non-negative at screening stage, an urine laboratory confirmation service is available to identify the exact metabolite or analyte present and give expert opinion for any action that needs to be taken. Simply take another two sets of samples using the urine collection kit for laboratory analysis.
