Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and other substances by embedding biomarkers within the strands as they grow. When gathered near the scalp, hair can potentially offer a detection duration of up to 3 months for alcohol and other substances. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.
A sample of hair measuring 1.5 inches with around 200 strands (similar in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the preferred sample size for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a 150mg sample is suggested. We advise using a jeweler’s scale for weighing the specimen. If scalp hair is unavailable, an equivalent quantity of body hair may be used. "Head hair" refers specifically to scalp hair, while "body hair" encompasses all other types such as facial and axillary hair.
Process Overview
The laboratory processing of drug test results includes four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves initially processing the sample into the lab's system, which includes ensuring the sample is sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.
Screening is a preliminary assessment for drugs of abuse. Although Screening is a cost-efficient means to exclude drug usage in most samples, a positive screen must be verified to be court-admissible. Samples with presumptive positive Screening results require a secondary confirmation.
Should a sample test presumptively positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. This phase involves retrieving drugs from hair at much lower concentrations than other techniques (such as urine or oral fluid), making hair drug screening one of the most challenging methodologies.
Positive Screening results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation, if necessary. The complete lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", the actual analysis is performed on the hair strand, not the follicle beneath the scalp.
