Definition - What does Masking Agent mean?
A masking agent is a substance used in order to try to conceal the presence of prohibited drugs in his or her system. Usually, the masking agent is ingested with the purpose of diluting or hiding any banned substance the person has consumed. Some masking agents are added directly to the urine sample at the time of providing the sample. Part of the duty of a good collection technician is to minimize the possibility of a donor bringing a masking agent into the bathroom during collection and assessing the sample after collection for suspicious samples that may have been tampered with. How successful a masking agent is in fooling a drug test depends on the type of agent used, the procedures of the drug testing location, and the type of drug test used.
