Recognized as a potent method, hair testing is used to identify drug and alcohol consumption. Hair strands retain biomarkers within their fibers throughout growth, delivering an extended-term snapshot of alcohol and drug history. When obtained close to the scalp, hair can reveal alcohol and drug presence for up to roughly three months. Collecting hair is straightforward, hard to tamper with, and simple to transport.
A 1.5-inch portion of nearly 200 hairs (about the diameter of a #2 pencil) nearest the scalp yields 100mg of hair, which is ideal for both screening and confirmation. For EtG, extra panels, or over ten-panel tests, 150mg of the hair sample is suggested. It's advisable to measure the sample on a precision jeweler’s scale. Should scalp hair be unavailable, a comparable quantity of body hair can be gathered. References to head hair are specifically to scalp hair, whereas body hair refers to all other kinds of hair (facial, axillary, etc.).
Steps in the Process
Drug test analysis in the lab includes four main phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the primary phase where a sample is entered into the lab’s system. This stage involves checking the sealing and proper shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data not furnished by an electronic chain of custody system.
Screening serves as an initial rapid check for substances of abuse. While economical, Screening chiefly excludes drug use, yet a positive result necessitates confirmation to be applicable in legal situations. Samples flagged as presumptively positive in Screening necessitate further verification.
With a sample identified as presumptively positive during Screening, additional hair from the initial batch is prepped for Extraction. Unlike other methods (e.g., urine or oral fluid), hair drug tests recover drugs at a far lower concentration, making them the most arduous to execute.
Positives from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing prior to confirmation as required. The entire process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
