Hair analysis is increasingly recognized for its efficacy in identifying substance use. Hair offers an extended snapshot of alcohol and drug usage by capturing biomarkers within the hair's developing fibers. When taken near the scalp, hair can offer a detection period of close to three months for substances. Collecting this sample is straightforward, tampering is relatively challenging, and transporting the sample is convenient.
A sample size of 1.5 inches, consisting of roughly 200 hair strands (comparable to the size of a standard pencil), when taken from the scalp, provides approximately 100mg, which is optimal for both preliminary screening and detailed confirmation tests. For tests involving EtG or exceedance of 10 panels, 150mg is advised. Utilizing a jeweler’s scale to measure the sample is suggested. If scalp hair is unavailable, an equivalent quantity of body hair can be used. "Head hair" refers strictly to scalp hair, whereas "body hair" includes all other types such as facial and axillary.
Process Overview
The laboratory processing for drug testing consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning initiates the sample's entry into a laboratory system. This phase ensures the sample was correctly sealed and delivered, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes any needed data not included in an electronic custody system.
Screening is a preliminary test for drugs. While Screening is economically efficient to eliminate drug use in most cases, a positive result requires validation to be legally defensible. Presumptively positive samples from Screening necessitate further confirmation.
Should a sample test positive during Screening, additional hair is extracted from the original specimen for further analysis. This phase involves drug extraction from hair at significantly lower levels compared to other methods (such as urine or oral fluid), rendering hair drug testing the most complex methodology.
Positive screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing prior to confirmatory testing as required. Throughout the laboratory procedure, from the initial Accessioning to final Confirmation, processes adhere to CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.
