Hair screening has emerged as an effective method for identifying drug and alcohol consumption. Hair captures long-term evidence of alcohol and drug use by embedding biomarkers within the strands of hair as it grows. When harvested near the scalp, it offers a detection period for alcohol and drugs of up to around three months. Hair collection is straightforward, relatively tough to tamper with, and easy to transport.
A sample measuring 1.5 inches, containing roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp, supplies 100mg of hair, which is ideal for evaluation and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is advisable. It's recommended to use a jeweler’s scale for weighing the specimen. If scalp hair isn't available, a comparable quantity of body hair may be used. "Head hair" specifically refers to scalp hair, while "body hair" pertains to all other styles (facial, axillary, etc.).
Process Overview
The key stages in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is integrated into the lab's system. It involves confirming the sample was correctly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry not handled by an electronic chain of custody system.
Screening is a preliminary quick scan for drugs of abuse. Although it is a cost-efficient method for excluding drug use in most samples, a positive screen requires confirmation to stand up in court. Samples flagged as presumptively positive during Screening need secondary validation.
When a sample is presumptively positive at the Screening stage, additional hair is extracted from the initial sample for the Extraction process. Here, drugs are isolated from hair at much lower concentrations than those found in other methods (e.g., urine or oral fluid), which makes hair drug screening one of the toughest methodologies to execute.
Confirmation tests for any positive screening outcomes are conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The entire laboratory process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair classification and in compliance with ISO / IEC 17025 standards.
