Solid-phase extraction and GC/MS quantitation of cocaine, ecgonine methyl ester, benzoylecgonine, and cocaethylene from meconium, whole blood, and plasma. A variety of immunoassays has been used for the initial testing of meconium extracts: EIA (63)(67), RIA (47)(58)(59), FPIA (46)(60)(61), and kinetic interaction of microparticles in solution (KIMS) (61).

Some drug testing policies do require extensive testing that involves risky and safety-sensitive jobs.
