Hair testing is now regarded as an effective method for identifying drug and alcohol consumption. Hair can capture biomarkers within the strands as they grow, offering a long-term record of these substances. If cut close to the scalp, hair can offer a detection window of up to three months for alcohol and related substances. Collection is straightforward, tampering is quite challenging, and it is easy to transport.
A 1.5-inch sample, roughly equating to 200 hairs (akin to the width of a #2 pencil), from near the scalp yields 100mg of hair, ideal for testing and corroboration. For testing EtG, additional panels, or for tests exceeding 10 panels, a 150mg sample is advisable. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair is absent, an equivalent quantity of body hair can be used. The term head hair specifically denotes scalp hair. Body hair includes all other hair types (e.g., facial, axillary, etc.).
Process Overview
There are four main stages in the lab processing of a drug test: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial processing of a sample into the lab's system. This includes confirming that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and entering any additional data not covered by an electronic chain of custody system.
Screening is a preliminary, cost-effective method for identifying drugs of abuse and excluding drug use in the majority of samples. However, for legal credibility, positive screens must be confirmed. Presumptive positives require further confirmation testing.
For samples suspected of positivity in Screening, additional hair is separated from the original collection and prepared for Extraction. This step isolates drugs at considerably lower concentrations than other testing techniques (e.g., urine or oral fluid), highlighting the complexity of hair drug analysis.
Positive Screening results undergo Confirmation with either GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples are cleansed before Confirmation as necessary. The entire process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair category and in compliance with ISO/IEC 17025 accreditation standards.
