Hair analysis is now recognized as an effective mechanism for identifying alcohol and drug consumption. Hair can offer a comprehensive view over extended periods by embedding biomarkers in its strands during growth. When clipped near the scalp, it can reveal drug and alcohol usage for up to around three months. Collecting hair is straightforward, moderately resistant to tampering, and convenient to mail.
A 1.5-inch segment of roughly 200 hair strands (approximately the thickness of a #2 pencil) from the scalp will yield 100mg of hair, optimal for analysis. For EtG, enhancements, and/or examinations exceeding 10 panels, 150mg is advisable. It's suggested to weigh the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent portion of body hair is suitable. By head hair, we mean scalp hair exclusively. Body hair includes all other types (facial, underarm, etc.).
Process Overview
The laboratory processing of a drug test outcome involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary processing of a sample within a lab's system. This process encompasses checking that the sample was appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input not covered by an electronic chain of custody system.
Screening entails a preliminary quick assessment for drug abuse. Though Screening is a cost-efficient method for eliminating drug use in the bulk of samples, a positive screen requires confirmation for legal admissibility. Any samples that show a positive indication in Screening mandate a supplementary confirmation.
If a sample shows a positive indication in the Screening phase, more hair is obtained from the original specimen and prepared for Extraction. In this phase, drugs are withdrawn from hair at much lower concentrations than in other approaches (for instance, urine or oral fluid), rendering hair drug screening the most challenging method to execute.
Confirmation of any positive screen is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating a positive result undergo washing before confirmation as necessary. The comprehensive lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although frequently called "hair follicle tests," the test evaluates the hair strand itself, not the follicle beneath the scalp.
