Hair assessments are now viewed as a crucial method in identifying alcohol and drug consumption. Hair captures a prolonged record of substances by embedding biomarkers within the strands of the hair as it grows. When extracted near the scalp, up to an approximately 3-month monitoring period for both alcohol and other substances can be achieved. Hair is straightforward to gather, relatively resistant to tampering, and convenient for transportation.
A 1.5-inch collection of roughly 200 hair strands (comparable to the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the preferred quantity for both initial screening and additional confirmation. For evaluations featuring EtG, supplementary options, and/or examinations exceeding 10 panels, 150mg of the hair specimen is advised. Utilizing a jeweler’s scale to weigh the sample is recommended. In the absence of scalp hair, an equivalent amount of body hair can be obtained. The term "head hair" specifically refers to scalp hair alone, while "body hair" encompasses all other types of hair (e.g., facial, axillary).
Process Overview
The principal stages involved in processing a sample for drug testing are Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample undergoes initial processing into a lab's system. This step involves ensuring the sample is appropriately sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any incomplete data from an electronic chain of custody system.
Screening involves a preliminary, rapid evaluation for substance abuse. Though Screening is an economic way to exclude drug presence in most samples, a positive result must undergo confirmation to be valid in a legal setting. Any samples that return a presumptive positive from Screening mandate further confirmation.
Should a sample exhibit a presumptive positive during Screening, additional hair is extracted from the initial collection and prepared for the Extraction phase. Here, substances are extracted from hair at a significantly lower concentration than apply in other methods (e.g., urine or oral fluid), reinforcing why hair drug screening presents the most complex challenge.
The Confirmation of any positive outcomes from the Screening phase is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples are cleansed ahead of confirmation as necessary. The comprehensive laboratory process, from Accessioning through to Confirmation, is assessed under the guidance of both the CAP (College of American Pathologists) Hair criterion and the ISO / IEC 17025 accreditation standards.
