6-Monoacetylmorphine(6-MAM) Panel Test is used for in vitro quantitative detection of 6-Monoacetylmorphine content in human urine. 6-MonoacetyImorphine (6-MAM) is one of three active metabolites of heroin (diacetylmorphine), the others being morphine and the much less active 3-acctyImorphinc (3-ACM). 6-MAM is rapidly created from heroin in the body, and then is either metabolized into morphine or excreted in the urine.
