Hair testing has emerged as a robust method for identifying drug and alcohol consumption. Hair offers a prolonged timeline of alcohol and drug usage by encapsulating biomarkers within the strands of growing hair. When collected near the scalp, hair provides a detection window for alcohol and drugs of up to approximately 3 months. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch hair sample containing roughly 200 strands (comparable to the thickness of a #2 pencil) nearest the scalp will yield 100mg of hair, which is the optimal sample amount for screening and verification. For EtG, additional requirements, and/or tests exceeding 10 panels, a 150mg specimen is advised. We suggest using a jeweler's scale to measure the specimen. In cases where scalp hair is unavailable, an equivalent quantity of body hair can be collected. When mentioning head hair, we exclusively mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary stage of handling a sample within a laboratory's system. This involves checking that the sample was securely sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and executing any additional data entry not covered by an electronic chain of custody system.
Screening conducts an initial rapid assessment for drugs of abuse. While Screening serves as a cost-effective measure to exclude drug use in most samples, a positive result requires confirmation to be court-admissible. Any samples showing a presumptive positive in Screening necessitate further confirmation.
Should a sample show a presumptive positive in the Screening phase, further specimen hair is extracted for the Extraction process. During this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting why hair drug screening is the most intricate methodology to undertake.
Confirmation of any positive screen outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS analysis. All samples with presumptive positives are cleansed before confirmation as required. From Accessioning to Confirmation, the complete laboratory process is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.
