Abstract
Though easiness and availability of a screening test are important factors, its correctness is most important for a drug abuser's arrest according to screening results. The use of Triage® in screening tests to detect stimulants was examined.
Abusers' urine samples contained methamphetamine at the concentration of which ranges from 1μg/ml to 479 μg/ml, and 66 μg/ml(n=68) on the average. Triage® showed negative reaction at 1000 μg/ml to 1500 μg/ml, even though there was a high concentration of methamphetamine. Triage® gives false negative result, even when there is a very high concentration of stimulant present in the urine. We should take this into consideration.
