Hair testing is now recognized as an effective instrument for identifying drug and alcohol consumption. Hair offers a prolonged overview of substance use by embedding biomarkers within the fibers of the growing hair strand. When gathered near the scalp, hair delivers up to a roughly 3-month detection period for alcohol and drug use. Hair collection is straightforward, challenging to tamper with, and convenient to send.
An ideal sample for analysis and confirmation involves a 1.5-inch segment of approximately 200 strands of hair (about the thickness of a #2 pencil) closest to the scalp, yielding 100mg of hair. For EtG, additional tests, and/or assessments surpassing 10 panels, 150mg is advised. We suggest using a jeweler's scale for determining the specimen's weight. In cases where scalp hair isn't available, a similar quantity of body hair is acceptable. When discussing head hair, we specifically reference scalp hair. Body hair encompasses any other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial intake of a sample into the laboratory’s system. This step includes ensuring the sample was sealed and dispatched correctly, designating a random LAN (Laboratory Accessioning Number), and addressing any supplementary data entry not provided by an electronic chain of custody system.
Screening is a preliminary examination for drugs of abuse. While Screening is an economical way to eliminate drug usage for most samples, a positive screen necessitates confirmation to be legally admissible. Samples that test presumptively positive in Screening require additional confirmation.
When a sample tests presumptively positive in the Screening phase, additional hair is extracted from the initial sample and processed for Extraction. Here, drugs are extracted from hair at significantly lower concentrations than other methods (such as urine or oral fluid), making hair drug testing the most challenging methodology to perform.
Confirmation of positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptive positive undergo a wash prior as required for confirmation. The entire process from Accessioning to Confirmation is vetted under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
