Urine Testing
Easy collection. Low cost. Most used.
Collection
Urine testing requires the donor to collect urine in a cup. The donor is given a sterile collection cup and instructed to collect specimen in the cup. The donor is directed and agrees to provide an unadulterated specimen.
Detection
The majority of illegal substances remain in the urine for up to a week, with the exception of marijuana which can leave detectable traces for up to a month, particularly in the case of heavy users.
Numerous factors influence how long drugs remain present in the system given that every body functions differently. Some of these factors include the amount of drugs that were consumed, metabolic rate, and the volume of fluids that have been excreted after the drug use.
Urine drug testing is the only testing method approved for federally-mandated drug testing and is the most common choice for student and employee drug testing, due to its reliability and affordability.
