Hair analysis has evolved into an effective means for identifying alcohol and drug consumption. By keeping biomarkers within the hair's fibers as it grows, hair offers an extensive record of substance use. When taken from near the scalp, hair can yield a detection period of up to roughly three months for alcohol and drugs. Collecting hair is straightforward, relatively resistant to tampering, and convenient to transport.
Securing a 1.5-inch section of roughly 200 hairs (similar to the size of a #2 pencil) nearest the scalp results in 100mg of hair, deemed the optimal sample for both screening and confirmation. For EtG, additional tests, and/or panels exceeding ten, a 150mg specimen is advised. Using a jeweler’s scale to weigh the sample is suggested. If scalp hair isn’t present, equivalent body hair can be substituted. Head hair specifically refers to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The primary stages in the laboratory processing of drug test samples are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses integrating the sample into the laboratory system initially. This process involves verifying the proper sealing and shipping of the sample, allocating a unique LAN (Laboratory Accessioning Number), and accomplishing any supplementary data input absent from an electronic custody system.
Screening executes a preliminary check for substance misuse. Although Screening offers a cost-efficient approach to discount substance use in most specimens, a positive screening result necessitates additional confirmation for court validation. Presumptive positives in Screening require subsequent verification.
For samples testing presumptive positive in Screening, additional hair is taken from the original sample to prepare for Extraction. During this phase, substances are extracted from hair at considerably lower concentrations than in other samples (e.g., urine or saliva), rendering hair drug testing as the most complex methodology.
Confirmation of any presumptive positive screening outcome is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples labeled presumptive positive undergo washing as required before confirmation. The whole laboratory workflow from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
