Hair analysis has emerged as an effective means for identifying substance consumption. Hair captures a lengthy record of drugs and alcohol by embedding markers within the fibers of the hair as it grows. When collected close to the scalp, hair offers an alcohol and drug detection span of up to roughly three months. Hair is straightforward to collect, moderately resistant to tampering, and conveniently transportable.
A 1.5-inch hair sample consisting of about 200 strands (comparable to the width of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal quantity for screening and verification. For EtG, supplementary tests, and tests exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the sample weight with a jeweler’s scale. In the absence of scalp hair, a similar amount of body hair can be collected. By head hair, we refer specifically to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test encompasses Accessioning, Screening, Extraction, and Confirmation as the primary phases.
Accessioning pertains to the initial incorporation of a specimen into a laboratory’s framework. This involves checking the secure sealing and proper shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry absent from an electronic chain of custody setup.
Screening executes a preliminary rapid test for substance abuse. While Screening serves as a cost-efficient method to dismiss substance usage for most samples, a positive screen requires confirmation for court admissibility. Samples with a presumptive positive result in Screening necessitate a follow-up confirmation.
If a sample shows a presumptive positive in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. During this phase, drugs are extracted from hair at concentrations more diluted than in other methods (such as urine or oral fluid), rendering hair drug screening a challenging method to execute.
Confirmation for any positive screening outcome is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo cleaning before confirmation as necessary. The comprehensive lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 certification standards.
