Hair testing has gained recognition as an effective mechanism for identifying drug and alcohol consumption. It delivers an extended timeline of alcohol and other drug usage by encapsulating biomarkers within the fibers of the developing hair strand. When sourced near the scalp, hair can offer a detection period of approximately 3 months for alcohol and other drugs. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A sample size of 1.5 inches consisting of roughly 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the specimen is suggested. The use of a jeweler's scale for weighing the specimen is recommended. If scalp hair isn't accessible, a comparable volume of body hair may be utilized. In reference to head hair, it is exclusively scalp hair. Meanwhile, body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The process in the lab for processing a drug test outcome includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.
In the Accessioning phase, the sample is initially processed into the lab’s system. This entails confirming proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any other data entry absent from an electronic chain of custody system.
The Screening phase includes an initial rapid test for substances of abuse. Although Screening is a cost-effective means to rule out substance consumption in the bulk of samples, any positive screen mandates confirmation to be acceptable in legal proceedings. Samples that show presumptive positivity in Screening necessitate a secondary confirmation.
Should a sample appear presumptively positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. In this phase, substances are extracted from hair at a notably lower concentration than with other techniques (e.g., urine or oral fluid), making hair drug screening the most challenging technique to execute.
For any positive screen result, Confirmation is done using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing as required before confirmation. From Accessioning to Confirmation, the entire lab process is evaluated following both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
