Hair testing is recognized as an effective method for detecting substance use. By embedding biomarkers within the fibers of hair as it grows, hair offers a prolonged record of alcohol and drug consumption. Hair samples taken near the scalp can reveal a roughly 3-month span of drug and alcohol history. Collecting hair is straightforward, somewhat resistant to tampering, and easy to transport.
A hair sample measuring 1.5 inches, encompassing around 200 strands (approximately the thickness of a #2 pencil) nearest to the scalp, yields 100mg, which is the optimal amount for both screening and confirmation. For EtG, additional parameters, or tests exceeding 10 panels, 150mg of the sample is suggested. A jeweler's scale is recommended for weighing the sample. If scalp hair is unobtainable, an equivalent amount of body hair is permissible. Head hair strictly refers to scalp hair, whereas body hair includes all other types (facial, axillary, etc.).
Process Overview
The process of lab analysis for a drug test consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary handling of a sample into a lab's workflow. This phase includes checking the proper sealing and shipping of the sample, generating a unique LAN (Laboratory Accessioning Number), and inputting any data not captured by an electronic chain of custody system.
Screening conducts an initial rapid evaluation for drug presence. While Screening provides a cost-efficient method to negate drug use in most samples, results indicating drug presence must be confirmed before they can be used legally. Samples that test presumptively positive in Screening require further confirmation.
For samples indicating a presumptive positive in Screening, additional hair is extracted from the original collection for the Extraction process. During this phase, drug compounds are isolated from hair at concentrations significantly lesser than in alternative methods (e.g., urine or oral fluid), highlighting the complexity of hair drug evaluation.
Confirmation of positive screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS technology. All samples indicating presumptive positivity undergo washing before confirmation if necessary. The comprehensive lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accredited by ISO / IEC 17025 norms.
