The Psychemedics Microplate EIA For Benzodiazepines in Hair is an in vitro diagnostic device for the qualitative detection of benzodiazepines in hair. The assay is intended for use in workplace settings for the qualitative analysis of human head and body hair. The assay uses a cutoff calibrator of 1 ng oxazepam/10 mg hair.

Psychemedics plans to perform this test at one site. Psychemedics has not performed an evaluation of reproducibility at different laboratories.

The Psychemedics Microplate EIA For Benzodiazepines in Hair provides only a preliminary analytical test result. A more specific alternate chemical method must be used to obtain a confirmed analytical result. Liquid Chromatography/Mass spectrometry/Mass spectrometry (LC/MS/MS) using deuterated internal standards in multiple reaction monitoring (MRM) mode is the confirmatory method used by Psychemedics Corporation. This confirmatory method uses a cutoff of 0.2 ng of the identified benzodiazepine/10 mg hair.

Indications for use as stated in the FDA summary.
