Hair testing has grown into a significant method for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of a developing hair strand, hair reveals an extended history of substance use. When sampled from the scalp area, hair can reveal a detection period of up to roughly three months for substances. Hair collection is uncomplicated, somewhat hard to manipulate, and simple to transport.
A 1.5-inch portion of approximately 200 hairs (about the diameter of a #2 pencil) adjacent to the scalp will provide 100mg of hair, which is the optimal sample size for analysis and confirmation. For EtG, supplemental tests, and/or panels exceeding 10, a 150mg sample is suggested. It's advisable to assess the hair sample's weight using a jeweler’s scale. If scalp hair cannot be obtained, an equivalent mass of body hair is acceptable. In mentioning head hair, we exclusively refer to scalp hair. Body hair encompasses all remaining hair types (e.g., facial or axillary).
Process Overview
The laboratory processing of a drug test result encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of the sample into a laboratory’s workflow. This phase involves verifying proper sample sealing and shipping, allocating a random LAN (Laboratory Accessioning Number), and finalizing necessary data input not included in an electronic chain of custody framework.
Screening involves an initial swift assessment for substance abuse. Although Screening is an economical approach to eliminate drug use for most samples, a positive finding necessitates confirmation for legal validity. Samples with a presumptive positive in Screening necessitate a secondary confirmation.
For samples suspected to be positive during Screening, additional hair is extracted from the initial sample for Extraction. This phase involves extracting drugs from hair at minimal concentrations compared to other techniques (e.g., urine or oral fluid), highlighting why hair drug screening constitutes the most intricate method.
Any positive screen results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples are cleansed before Confirmation if required. Every laboratory procedure from Accessioning through Confirmation adheres to the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
