Hair analysis is increasingly regarded as an effective method for identifying drug and alcohol consumption. The hair captures a prolonged record of alcohol and drug exposure by embedding biomarkers within the hair fiber during growth. When obtained near the scalp, hair can signify up to an estimated three-month period for alcohol and drug detection. Collecting hair is straightforward, fairly resistant to tampering, and convenient to transport.
A sample of 1.5 inches comprising around 200 hair strands (comparable to a #2 pencil in size) nearest to the scalp yields 100mg of hair, considered the optimal quantity for both screening and confirmation. For EtG, additional analyses, and/or tests exceeding 10 panels, a 150mg sample is preferable. We advocate for measuring the sample using a jeweler's scale. Should scalp hair be unavailable, a proportional amount of body hair is viable. When discussing head hair, we mean scalp hair exclusively. Body hair pertains to all other kinds of hair (such as facial, armpit, etc.).
Process Overview
The quartet of pivotal stages in a lab's processing of a drug test outcome encompasses Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a laboratory's framework. This phase involves confirming the proper sealing and shipping of the sample, assigning a distinct LAN (Laboratory Accessioning Number), and fulfilling any supplementary data input absent in an electronic chain of custody process.
Screening carries out a preliminary rapid assessment for substance abuse. Although Screening serves as an economical method to negate drug usage for the bulk of samples, a positive screen necessitates confirmation for legal admissibility. All samples indicating positive presumptions in Screening require further confirmation.
Should a sample exhibit a presumptive positive in the Screening phase, additional hair is retrieved from the initial sample and readied for Extraction. During this phase, substances are extracted from hair at significantly reduced concentrations compared to other techniques (e.g., urine or oral fluid), explaining why hair drug analysis is the most challenging technique to execute.
Confirmation for any positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing as necessary before confirmation. The complete lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair criteria and the accreditation to ISO / IEC 17025 regulations.
