Hair analysis is increasingly recognized as an effective means for identifying drug and alcohol consumption. The fibers within hair strands capture biomarkers, offering a comprehensive history of substance use. When clipped near the scalp, hair can reveal alcohol and drug presence for up to three months. It is easy to gather, challenging to tamper with, and straightforward to send.
A 1.5-inch segment of around 200 hair strands (resembling the thickness of a #2 pencil) nearest the scalp results in 100mg of hair, the perfect amount for analysis and verification. For EtG or extensive tests exceeding 10 panels, 150mg of hair is advised. Utilizing a jeweler’s scale is recommended to weigh the sample. Where scalp hair is absent, an equivalent quantity of body hair can be utilized. "Head hair" strictly indicates scalp hair, whereas "body hair" includes all other hair forms (e.g., facial or axillary hair).
Process Overview
The procedure for processing a drug test in a lab encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the phase where a sample initially enters a lab's system. This step ensures the sample was properly sealed and transported, assigns it a unique LAN (Laboratory Accessioning Number), and records any remaining data absent from an electronic custody chain system.
Screening carries out a preliminary assessment for abused substances. Although screening economically dismisses drug presence in most cases, a positive result requires confirmation for court acceptability. Samples flagged as likely positive in screening need further verification.
In instances of presumed positivity during Screening, additional hair is taken from the initial sample for Extraction. This stage involves separating drugs from the hair at relatively minimal levels compared to other methods (such as urine or saliva), hence hair drug testing is notably intricate.
Positive screens are verified through GC/MS, GC/MS/MS, or LC/MS/MS. Necessary presumptive samples undergo cleaning before verification. From Accessioning to Confirmation, the entire lab operation is assessed against CAP (College of American Pathologists) Hair criteria and ISO/IEC 17025 accreditation.
