The use of hair testing is regarded as an effective means for identifying drug and alcohol consumption. The fibers of growing hair strands can trap biomarkers, thus providing a prolonged history of alcohol and drug consumption. When collected near the scalp, hair can offer a detection period of up to about three months for both alcohol and drugs. Hair sampling is straightforward, hard to alter, and convenient to transport.
A sample of 1.5 inches consisting of roughly 200 hair strands (equivalent to a #2 pencil’s thickness) closest to the scalp yields 100mg of hair, which is the preferred quantity for both screening and confirmation. For tests that include EtG, add-ons, and/or exceed 10 panels, a specimen of 150mg is advised. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair isn't available, an equivalent quantity of body hair may be collected. Here, head hair denotes specifically scalp hair. Body hair includes all other hair types (such as facial and axillary).
Process Overview
The drug test result processing in the lab involves four major stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary stage of incorporating a sample into a laboratory system. It comprises verifying the integrity and proper shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entries not covered by an electronic chain of custody system.
The Screening stage performs an expedited check for drugs of abuse. Although Screening is a cost-efficient method to dismiss drug presence in most samples, a positive result must be confirmed for legal admissibility. Samples with presumptive positive results in Screening need further confirmation.
If the Screening stage results in a presumptive positive, additional hair is extracted from the original specimen and prepared for Extraction. During Extraction, drugs are retrieved from the hair at much lower concentrations compared to other methods (like urine or oral fluids), highlighting the complexity of hair drug testing.
A confirmed positive result from Screening is verified using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptively positive samples undergo washing as required. The complete lab process, ranging from Accessioning to Confirmation, is assessed under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
