Seen as a potent method, hair testing effectively identifies drug and alcohol consumption. By embedding biomarkers within hair fibers, it offers a long-term overview. When hair near the scalp is collected, it can reveal up to a 90-day history of alcohol and drug use. Gathering hair is straightforward, hard to tamper with, and convenient to transport.
Collecting a 1.5-inch section of approximately 200 hair strands, equivalent to the width of a #2 pencil, from the scalp yields 100mg, which is optimal for both screening and confirmations. For additional testing like EtG or tests exceeding 10 panels, a 150mg sample is suggested. It's advisable to weigh the sample using a jeweler's scale. If scalp hair isn't available, body hair in equivalent quantity can be utilized. References to head hair pertain specifically to scalp hair. Body hair encompasses all other types (facial, underarm, etc.).
Process Overview
The laboratory process of a drug test is divided into four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the step where samples are first introduced into the laboratory's system. This includes ensuring the sample is correctly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and inputting any additional data not handled by an electronic chain of custody system.
Screening involves an initial, cost-efficient assessment for drugs of abuse. Although Screening helps eliminate the majority of samples for drug usage, results that screen positive must be confirmed for legal admissibility. Samples showing a presumptive positive in Screening need further confirmation.
Should a sample test presumptive positive during Screening, additional hair from the initial sample is used for Extraction. This stage extracts drugs from hair at much lower concentrations compared to other methods (like urine or saliva), making hair drug screening particularly challenging.
Positive Screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples are cleaned before confirmation as necessary. The entire process from Accessioning to Confirmation is audited according to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
