How long do stimulants typically remain detectable in a urine immunoassay?

Stimulants, such as amphetamines and cocaine, are substances that can be detected in urine through immunoassay testing. The typical detection window for most stimulants is around 2 to 3 days after use. This is because the metabolites of stimulants metabolize in the body at a rate that leads to their presence in urine for about this duration.

While some factors can influence the exact timing—such as the dosage taken, individual metabolism, hydration levels, and frequency of use—generally, a detection window of up to 3 days is a reliable guideline for many common stimulant substances. After this period, the likelihood of detection decreases significantly, which aligns well with the answer provided.

For other options, detection times such as 1 day or as long as 7 days are not typical for standard use of stimulants in the average person. Urine tests are less likely to detect stimulants after 3 days, particularly in the context of occasional use.
