Hair testing is widely recognized as an effective means for identifying drug and alcohol consumption. The hair retains a protracted record of alcohol and other drugs by encasing biomarkers within its growing strands. When hair is gathered near the scalp, it can reveal a detection span of up to three months for alcohol and drugs. Collecting hair is straightforward, somewhat resistant to tampering, and simple to transport.
A 1.5-inch fragment of roughly 200 strands of hair (comparable to the width of a #2 pencil) nearest to the scalp provides 100mg of hair, the optimal sample for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a recommendation of 150mg of the sample is given. It is suggested to weigh the sample using a jeweler’s scale. If scalp hair cannot be accessed, a comparable quantity of body hair may be used. The term head hair specifies only scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The primary stages in laboratory drug test processing consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary processing of a sample into the laboratory’s database. This phase ensures the sample was correctly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and concludes any supplementary data entry absent from an electronic chain of custody system.
Screening entails an initial rapid assessment for substances of abuse. Although Screening is a cost-efficient method to exclude drug use on most samples, a positive screen must be verified for legal credibility. Samples with presumptive positives during Screening ought to receive further confirmation.
Should a sample prove presumptively positive in the Screening stage, additional hair is extracted from the initial sample and prepped for Extraction. Here, drugs are filtered from hair at a significantly reduced concentration compared to other techniques (ex. urine or oral fluid), thus rendering hair drug screening one of the most intricate methodologies to execute.
Confirmation of positive screening outcomes is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair designation and the compliance with ISO / IEC 17025 standards.
