Test Details

Use

Detect and confirm the presence of heroin metabolite (6-acetylmorphine). Note: 6-Acetylmorphine [6-AM] has a short half-life and is further metabolized to morphine. It is most likely to be detected within the first 24 hours following heroin use. Consequently, specimens collected more than 24 hours post dose may test negative for 6-AM.
