Recognized as an effective means for identifying drug and alcohol usage, hair testing offers a substantial historical record by embedding biomarkers within the strands of hair as they grow. When collected near the scalp, hair can reveal up to a roughly three-month timespan for detecting alcohol and other drugs. Collecting hair is straightforward, hard to tamper with, and convenient for transportation.
A sample measuring 1.5 inches comprising approximately 200 hairs (around the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is optimal for testing and confirming results. For EtG, additional analyses, and/or tests exceeding 10 panels, 150mg of the sample is advised. Measuring the sample with a jeweler’s scale is recommended. Should scalp hair be unavailable, an equivalent amount of body hair can be used. When we mention head hair, it pertains exclusively to scalp hair. In contrast, body hair denotes all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial procedure of a sample being processed within a laboratory's system. This process involves ensuring the sample was correctly sealed and delivered, allocating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent from an electronic chain of custody system.
Screening serves as an initial swift assessment for drugs of abuse. While Screening is a financially efficient method to dismiss drug usage for most samples, a positive screen necessitates confirmation to be valid in legal proceedings. Samples presumptively positive during Screening require additional confirmation.
In cases of presumptive positivity in the Screening phase, additional hair is extracted from the initial sample and readied for the Extraction phase. During this phase, drugs are withdrawn from hair at much lower concentrations than other methods (e.g., urine or oral fluid), rendering hair drug screening the most challenging procedure.
Confirmation of any positive screening finding is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo a washing process if necessary. The comprehensive laboratory process from Accessioning to Confirmation is evaluated according to both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 standards.
