Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair retains a comprehensive history of substances by encapsulating biomarkers within the hair strand's growth fibers. When sourced from near the scalp, it offers an approximately three-month detection duration for alcohol and drugs. The collection process is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch hair segment, with roughly 200 strands (comparable to the thickness of a #2 pencil) nearest the scalp, yields 100mg, which is the optimal amount for assessment and verification. For EtG, supplements, and/or tests exceeding 10 panels, a sample of 150mg is suggested. It is advisable to use a jeweler's scale for measuring the sample. If scalp hair is unavailable, comparable body hair may be used as a substitute. Head hair refers exclusively to scalp hair, whereas body hair includes other types such as facial and axillary hair.
Process Overview
The principal phases in the laboratory processing of a drug test outcome encompass Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the lab’s system. This phase involves ensuring the sample’s proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry if absent from an electronic chain of custody system.
Screening provides a preliminary check for drug abuse. Though Screening is cost-efficient for excluding drug use in most samples, a positive result necessitates validation to be considered legally admissible. Presumptive positive samples in Screening require secondary confirmation.
If a sample yields a presumptive positive in the Screening phase, additional hair is extracted from the initial specimen for the Extraction process. During Extraction, drugs are retrieved from hair at much lower concentrations than alternative methods (e.g., urine or oral fluid), contributing to the complexity of hair drug testing.
Confirmation for any positive screening outcome occurs via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
