Hair testing is recognized as an effective means for identifying alcohol and drug consumption. Hair holds a comprehensive record of alcohol and drug use by encapsulating biomarkers within the strands of growing hair. When obtained near the scalp, hair can offer a detection window of up to roughly three months for alcohol and drugs. Hair is straightforward to collect, challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches, made up of around 200 hair strands (similar in size to a #2 pencil) nearest to the scalp, will yield 100mg of hair, which is the optimal quantity for screening and confirmation. For EtG, add-ons, and/or evaluations exceeding 10 panels, 150mg of the sample is advised. It is recommended to assess the weight of the sample using a jeweler’s scale. If hair from the scalp is not obtainable, a similar quantity of body hair can be gathered. By head hair, we mean exclusively scalp hair, whereas body hair includes all other hair categories (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a sample within a laboratory's system. This comprises verifying the proper sealing and shipping of the sample, designating a random LAN (Laboratory Accessioning Number), and accomplishing any remaining data entry absent from an electronic chain of custody system.
Screening consists of an initial swift examination for drugs of abuse. Although Screening is a cost-effective approach to exclude drug use in most samples, a positive screen must be validated to be admissible in legal proceedings. Samples that show presumptive positive results in Screening necessitate an additional confirmation.
If a sample shows a presumptive positive outcome in the Screening phase, additional hair is retrieved from the original specimen for Extraction. Here, drugs are extracted from hair at significantly lower concentrations than in alternative methods (e.g., urine or oral fluid), which is why hair drug screening stands as the most complex methodology to execute.
The verification of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing before confirmation as required. The full laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation as per ISO / IEC 17025 standards.
