Hair assessments are now recognized as an effective mechanism for detecting the use of alcohol and narcotics. Hair strands contain a prolonged record of drug and alcohol consumption by encasing biomarkers within the fiber structure. When sourced near the scalp, hair samples can offer up to a three-month window for identifying alcohol and drug usage. Procuring hair samples is straightforward, somewhat resistant to tampering, and convenient for shipping.
An ideal sample involves a 1.5-inch segment consisting of roughly 200 hair strands (comparable to a #2 pencil), cut close to the scalp to provide 100mg of hair, which is optimal for screening and verification. For EtG, additional assays, and analyses beyond 10 panels, a 150mg sample is advisable. It is suggested that the specimen be weighed using a jeweler's scale. If scalp hair is not accessible, an equivalent volume of body hair can be used. When we talk about head hair, we strictly mean scalp hair. Body hair encompasses other varieties (such as facial and underarm hair).
Process Overview
The drug test result processing in a lab consists of four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves incorporating a sample into the laboratory system. This step confirms that the sample was secured and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and manages any extra data input not available via an electronic chain of custody method.
Screening provides a preliminary inspection for illicit drugs. While cost-effective for eliminating drug use in most samples, a positive screening still needs verification for legal validity. Any samples with a presumptive positive in Screening require additional confirmation.
If a sample tests presumptively positive during Screening, further hair is extracted from the primary specimen for the Extraction phase. Here, drugs are meticulously isolated from hair at concentrations lower than other techniques (e.g., urine, oral fluids), highlighting the complexity of hair drug assessments.
Confirmation for any positive screen result is achieved with GC/MS, GC/MS/MS or LC/MS/MS techniques. All samples with a presumptive positive result undergo washing as necessary before verification. The comprehensive lab procedure from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair designation and compliance to ISO / IEC 17025 criteria.

Note: Despite being commonly dubbed "hair follicle tests," the procedure examines the hair itself, not the follicle beneath the scalp.
