Hair testing has emerged as a robust method for identifying drug and alcohol consumption. Hair captures a long-standing record of alcohol and other drugs by embedding biomarkers in the strands of the growing hair. When gathered close to the scalp, hair can offer nearly a 3-month detection period for alcohol and other drugs. Hair collection is straightforward, relatively hard to tamper with, and convenient to transport.
A 1.5-inch portion comprising roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp will produce 100mg of hair, which is the ideal sample amount for screening and verification. For EtG, additional tests, and/or more than 10-panel tests, 150mg of the sample is suggested. We suggest weighing the sample with a jeweler’s scale. If scalp hair is not available, an equivalent volume of body hair can be utilized. When mentioning head hair, it refers exclusively to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
There are four primary stages in the laboratory procedure for processing a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial handling of a sample into a laboratory's system. This involves checking that the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not available through an electronic chain of custody system.
Screening involves a preliminary rapid scan for drugs of abuse. Though Screening is a cost-efficient way to eliminate drug usage for the majority of samples, a positive screen must be confirmed to be permissible in legal proceedings. Any samples that show a presumptive positive in Screening require a follow-up confirmation.
If a sample shows a presumptive positive in the Screening phase, more hair is taken from the original sample and readied for Extraction. At this stage, drugs are extracted from hair at a much lower concentration than in other methods (e.g., urine or oral fluid), which is why the hair drug screening is regarded as the most challenging method to conduct.
Confirmation of any positive screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as essential. The entire laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the certification to ISO / IEC 17025 standards.
