Hair testing is increasingly recognized as a potent method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug presence by embedding biomarkers within its fibers as it grows. When sampled from near the scalp, hair can reveal drug and alcohol use within roughly a 3-month timeframe. Hair is straightforward to collect, relatively challenging to tamper with, and uncomplicated to transport.
A sample measuring 1.5 inches, comprising approximately 200 hair strands (comparable to the width of a #2 pencil), taken closest to the scalp, yields 100mg of hair—optimal for screening and confirmation. For EtG tests, additional analyses, or tests exceeding 10 panels, 150mg of specimen is advisable. Using a jeweler’s scale to weigh the specimen is suggested. Should scalp hair be unavailable, a corresponding quantity of body hair may be gathered. In the context of head hair, we specifically mean scalp hair. The term body hair encompasses all other hair variants (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial incorporation of a sample into a laboratory’s framework. This phase includes verifying proper sealing and shipping of the sample, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any additional data input absent in an electronic chain of custody system.
Screening is an initial, efficient examination for drug presence. While Screening provides a cost-effective means to exclude drug use for most samples, any positive screen must be corroborated to be court-admissible. Samples yielding presumptive positive results in Screening necessitate further confirmation.
If a sample presents a presumptive positive during Screening, additional hair is drawn from the original specimen and prepared for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than alternate methods (e.g., urine or oral fluid), marking hair drug screening as particularly challenging to execute.
Confirmation of any positive screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo washing as necessary. The comprehensive laboratory procedure from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
