Hair testing has gained recognition as an effective means to identify alcohol and drug consumption. Hair retains a long-term record of drug and alcohol use by encasing biomarkers in the fibers of the growing hair strand. When samples are taken near the scalp, they can provide an estimated 3-month window of detection for alcohol and other drugs. Hair is straightforward to collect, moderately challenging to alter, and convenient to transport.
A 1.5-inch segment of approximately 200 hair strands (roughly the size of a #2 pencil) near the scalp yields 100mg of hair, the optimum amount for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, 150mg of the sample is advised. It is advisable to use a jeweler’s scale for weighing the sample. If scalp hair is inaccessible, a comparable quantity of body hair can be gathered. Head hair specifically refers to scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into a laboratory’s system. This process includes checking that the sample was properly sealed and dispatched, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing additional data entry not covered by an electronic chain of custody system.
Screening consists of a preliminary rapid check for drugs of abuse. Although Screening is an economical method for excluding drug use in most samples, any positive results require confirmation for acceptability in legal proceedings. Samples presumptively positive in Screening necessitate further confirmation.
If a sample shows presumptive positivity in the Screening phase, more hair is extracted from the initial specimen for Extraction. During this stage, drugs are extracted from hair at a concentration far lower than in other testing methods (e.g., urine or oral fluid), leading to hair drug screening being one of the most complex testing methods.
Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples presumptively positive are washed prior to confirmation as needed. The comprehensive lab process from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
