Hair sampling is now regarded as an effective means for identifying drug and alcohol consumption. Hair captures a prolonged history by embedding biomarkers within the strands while they grow. When sourced near the scalp, it can offer up to a 3-month detection period for both alcohol and other drugs. Collecting hair is straightforward, less prone to tampering, and convenient to transport.
A sample size of 1.5 inches comprising roughly 200 hair strands (similar in thickness to a #2 pencil) near the scalp will provide 100mg, which is the optimal quantity for both screening and confirmation. For EtG, additional analyses, and/or tests beyond 10 panels, it is suggested to acquire 150mg of the specimen. It is advised to weigh the specimen using a jeweler’s scale. If scalp hair is not obtainable, a similar quantity of body hair can be collected. The term head hair specifically refers to scalp hair, while body hair encompasses all other hair types (such as facial or axillary hair).
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into the lab’s system, ensuring the sample's seal and proper shipment, assigning a LAN (Laboratory Accessioning Number) at random, and completing any remaining data entry tasks not covered by an electronic chain of custody system.
Screening conducts a preliminary assessment for substances of abuse. Although a cost-efficient approach to eliminate drug usage in most samples, any positive results from Screening must undergo confirmation to be valid in judicial proceedings. Any samples that are tentatively positive in Screening require a further verification.
Should a sample test tentatively positive during the Screening phase, additional hair is extracted from the initial sample for the Extraction phase. This phase involves extracting drugs from hair at notably lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring why hair drug screening is the most complex method to execute.
Confirmation of any positive screening outcomes is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Samples indicating tentative positive results are washed prior to confirmation when necessary. The comprehensive lab process from Accessioning to Confirmation is conducted under both the CAP (College of American Pathologists) Hair specifications and the accreditation according to ISO / IEC 17025 criteria.
