The Quest Diagnostics Hair Check-DT (PCP) is a test system that utilizes the IDS One-Step ELISA PCP Kit for the qualitative detection of Phencyclidine at or above 300 pg/mg in head hair samples. This test system has not been evaluated for use in specific user populations or with hair specimens other than the head. It is an in vitro diagnostic device intended exclusively for in-house professional use only and is not intended for sale to anyone.

The Quest Diagnostics Hair Check-DT (PCP) screening test provides only a preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed result. Gas Chromatograph - Mass Spectrometry operating in the selected ion monitoring (SIM) mode is the preferred method with deuterated internal standards. Other chemical confirmation methods are available. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are obtained.

Indications for use as stated in the FDA summary.
