Hair analysis has earned recognition as an effective means for identifying drug and alcohol consumption. Hair strands imbibe biomarkers within the fibers as they grow, offering a prolonged profile of alcohol and drug intake. When obtained near the scalp, this method can reveal a usage history spanning roughly three months for various substances. This technique is straightforward, moderately resistant to tampering, and easy to transport.
A sample size measuring 1.5 inches, comprising around 200 hair strands (approximately the girth of a #2 pencil), provides 100mg of hair, an optimal quantity for both screening and validation. For EtG assessments, additional examinations, and/or testing beyond ten panels, a sample of 150mg is advised. Utilizing a jeweler’s scale for weighing is suggested. If scalp hair cannot be collected, an equivalent quantity of body hair may be used. The term head hair specifically pertains to scalp hair, while body hair encompasses other categories (facial, axillary, etc.).
Process Overview
The primary stages in the laboratory processing of drug testing results are Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial integration into a lab’s system. This step involves confirming the sample's proper sealing and dispatch, generating a unique LAN (Laboratory Accessioning Number), and finalizing any outstanding data input not managed by an electronic chain of custody system.
Screening includes a preliminary assessment for substance misuse. While Screening efficiently negates drug presence in many samples, a positive outcome requires confirmation to be deemed valid in legal contexts. Samples suggesting positivity in Screening necessitate additional verification.
If Screening suggests a sample's positivity, additional hair is extracted from the initial sample and readied for Extraction. In this phase, substances are drawn from hair at significantly diminished concentrations compared to other methods (e.g., urine or oral fluid), establishing hair drug screening as the most challenging practice.
Any positive results during the Screening phase undergo Confirmation using GC/MS, GC/MS/MS or LC/MS/MS methods. Samples that presumptively test positive are cleansed prior to final confirmation if necessary. The complete laboratory chain from Accessioning to Confirmation undergoes thorough review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
