Hair assessments have emerged as an effective method for identifying drug and alcohol use. Hair traps biomarkers within its strands, providing an extensive historical record of substance intake. Sampling done near the scalp can offer a detection span of up to about three months for both alcohol and drugs. Collecting hair is straightforward, fairly resistant to tampering, and convenient to transport.
A 1.5-inch collection of around 200 hair strands (approximately the girth of a #2 pencil) next to the scalp yields 100mg, which is optimal for screening and verification. For EtG, add-ons, or tests exceeding 10 panels, a 150mg sample is advised. Using a jeweler's scale for weighing the sample is recommended. If scalp hair isn’t available, a similar quantity of body hair can be used. When noting head hair, it specifically means scalp hair, whereas body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result comprises four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the basic processing of a sample into a lab's system. This stage ensures the sample was correctly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional data entry not furnished by an electronic chain of custody system.
Screening conducts an initial rapid inspection for drugs of abuse. While it's a cost-efficient way to rule out drug use in most cases, a positive screen demands confirmation to be court-accepted. Any samples testing presumptively positive in Screening require a secondary verification.
When a sample shows a presumptive positive at the Screening stage, additional hair is sourced from the original specimen and prepped for Extraction. At this phase, drugs are extracted from hair at a considerably lower concentration than other methods (e.g., urine or oral fluid), which is why hair drug screening is the hardest to execute.
Confirmation of any screening positives is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed prior to confirmation as required. The complete lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation, as well as accredited to ISO / IEC 17025 standards.
