Recognized as a compelling method, hair testing has become integral in identifying drug and alcohol consumption. By capturing biomarkers within the hair strand's fibrous growth, hair provides an extensive timeline of alcohol and other drugs. When taken near the scalp, hair offers a detection scope of nearly three months for alcohol and drugs. It is straightforward to gather, notably challenging to tamper with, and simple to transport.
A hair sample of 1.5 inches, approximately 200 strands (roughly matching a #2 pencil in size), adjacent to the scalp yields 100mg, which is the optimal amount for evaluation and confirmation. For EtG, additional requests, or panels exceeding 10, a specimen of 150mg is suggested. Utilizing a jeweler’s scale for weighing the sample is advised. Should scalp hair be unavailable, an equivalent amount of body hair can be used. References to head hair are exclusively about scalp hair, while body hair includes all other types such as facial or axillary hair.
Process Overview
The procedure of processing a drug test result in a laboratory comprises four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the introductory process of integrating the sample within a laboratory’s framework. This phase involves ensuring the sample is properly sealed and sent, assigning a LAN (Laboratory Accessioning Number) randomly, and fulfilling any extra data entry absent from an electronic chain of custody system.
Screening is a preliminary, swift examination for substances of abuse. While it serves as a cost-efficient method to eliminate drug use in most cases, any positive outcome requires confirmation to be legitimate for legal proceedings. Presumptive positive samples in Screening necessitate secondary affirmation.
For presumptively positive samples in Screening, extra hair is extracted from the original specimen for the Extraction stage. Here, drug removal from hair is undertaken at a much reduced concentration compared to other techniques (such as urine or oral fluid), underscoring the complexity of performing hair drug screening.
Positive screening outcomes undergo confirmation using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples are cleansed pre-confirmation as necessary. The entire lab process from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
