## Indications for use
The Psychemedics homogeneous enzyme immunoassay (HEIA) for opiates in hair is an enzyme immunoassay for the preliminary qualitative detection of opiates in human head and body hair using a morphine calibrator at 2 ng morphine/10 mg hair for the purpose of identifying opiate use. This is an in vitro diagnostic device intended exclusively for Psychemedics use only and is not intended for sale to anyone. The Psychemedics homogeneous enzyme immunoassay for opiates in hair provides only a preliminary analytical test result. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. Liquid Chromatography/Mass Spectrometry/Mass Spectrometry (LC/MS/MS) is the preferred confirmatory method.
