Hair testing is recognized as an effective method for identifying drug and alcohol consumption. It offers a historical view of substance use by capturing biomarkers within the growing hair fibers. When hair is gathered near the scalp, it can reveal alcohol and drug use over a period of up to three months. Hair collection is straightforward, hard to tamper with, and simple to transport.
A 1.5-inch portion consisting of approximately 200 hair strands (comparable to the thickness of a #2 pencil) nearest the scalp will yield 100mg of hair, which is the preferred amount for examination and validation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the sample is suggested. It's advised to weigh the sample using a jeweler’s scale. If scalp hair is not accessible, a similar quantity of body hair might be used. The term head hair specifically pertains to scalp hair, while body hair includes all other types (facial, axillary, and so on).
Process Overview
The drug testing process in a lab consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample is introduced into the laboratory's system, ensuring it was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody protocol.
Screening is a preliminary assessment for drug presence. Although it is cost-efficient for ruling out drug use in most samples, a positive outcome needs confirmation to be considered valid in a legal context. Samples that are preliminarily positive during Screening require further confirmation.
In the event of a presumptive positive result in the Screening phase, additional hair is taken from the original sample for the Extraction process. Here, drugs are isolated from hair at a much lower concentration compared to other methods like urine or saliva tests, making hair drug testing the most complex to execute.
GC/MS, GC/MS/MS, or LC/MS/MS is employed for confirming any positive screening findings. All samples deemed presumptively positive are washed before confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair endorsement and ISO / IEC 17025 accreditation standards.
