Hair assessments are now regarded as a robust method for identifying drug and alcohol consumption. The hair captures a prolonged record of alcohol and other substances by securing biomarkers within the fibers of the developing hair strand. When obtained near the scalp, hair can deliver approximately a three-month detection span for alcohol and other drugs. Hair sample collection is straightforward, relatively challenging to tamper with, and convenient to transport.
A 1.5-inch segment of around 200 hair strands (roughly comparable to the width of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the ideal sample for assessments including screening and confirmation. For EtG, extended panels, and/or tests exceeding 10 panels, 150mg of the sample is advisable. It is suggested to use a jeweler’s scale to weigh the sample. If scalp hair is not an option, an equivalent quantity of body hair can be gathered. When head hair is mentioned, it specifically refers to scalp hair only. Body hair encompasses all other categories of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial handling of a sample within a laboratory’s framework. This encompasses verifying the sample’s sealing and correct shipping, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any additional data entry not supplied through an electronic chain of custody system.
Screening performs an initial rapid evaluation for substances of abuse. The Screening allows for a cost-effective exclusion of drug use in most samples; however, a screen that tests positive requires confirmation to be valid in legal settings. Any samples presumptively positive in Screening require further confirmation.
Should a sample test presumptively positive during the Screening stage, additional hair is extracted from the original sample and made ready for Extraction. During this phase, drugs are removed from hair at significantly lower concentrations than through alternative techniques (e.g., urine or oral fluid), which contributes to the complexity of hair drug testing.
Confirmation of any positive screening is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo a wash prior to confirmation as necessary. The entirety of the laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
