Hair analysis is increasingly regarded as an effective means for identifying drug and alcohol consumption. Hair retains a long-term record of substances by embedding biomarkers within the fibers of the growing hair shaft. When taken from near the scalp, hair can reveal alcohol and drug use within a span of about three months. Hair collection is straightforward, relatively hard to tamper with, and convenient to transport.
A hair sample of 1.5 inches consisting of approximately 200 strands (comparable to the thickness of a #2 pencil) near the scalp will yield 100mg, the optimal amount for evaluation and verification. For EtG, additional assessments, and tests exceeding 10 panels, 150mg of the sample is preferable. It is advisable to measure the sample with a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be used. Head hair specifically denotes scalp hair. Other hair types such as facial and axillary hair are classified as body hair.
Process Overview
The laboratory drug testing procedure encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves integrating a sample into the lab’s system initially. This step ensures the sample was correctly sealed and delivered, assigns a LAN (Laboratory Accessioning Number), and completes any data entry not managed by an electronic tracking system.
Screening serves as a preliminary examination for substance misuse. Though a cost-effective method to exclude drug use in most samples, a positive screening must be validated for legal acceptability. Samples testing positive in Screening necessitate a subsequent confirmation.
For samples testing positive in the Screening phase, additional hair is removed from the original sample for Extraction. Here, drugs are isolated from hair at a lower concentration than other methods (such as urine or oral fluid), highlighting the complexity of hair drug analysis.
Confirmation of screening positives occurs via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive samples undergo washing before confirmation as needed. The complete lab process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.
