Diagnostic accuracy of cannabinoid testing by liquid chromatography-tandem mass spectrometry in human hair

Abstract

Objective: To determine the diagnostic accuracy of Cannabinoids testing by LC-MS/MS in human hair and compare it with urine in civil heavy vehicle drivers. Methods: Current study was a diagnostic accuracy study done in "Armed Forces Institute of Pathology Rawalpindi, Pakistan"from February to November 2017. Urine and hair samples were collected by non-probability convenient sampling technique from 151 heavy vehicle drivers from Punjab. Hair and urine samples were collected from each subject. Separation of compounds was performed on Agilent Poroshell and analyzed using 6460 Triple Quadrapole LC-MS along-with software Mass hunter.
