Hair testing is increasingly recognized as an effective method for detecting drug and alcohol consumption. Hair offers an extended-term record of substances by embedding biomarkers within the hair as it grows. When taken near the scalp, hair can offer close to a 3-month window of detection for alcohol and drugs. The sample is easy to obtain, challenging to tamper with, and simple to transport.
A 1.5-inch hair segment of roughly 200 individual strands (approximately the diameter of a #2 pencil) is needed for an ideal screen and confirmation test, yielding 100mg of hair. For tests like EtG or those with more than 10 panels, 150mg is advised. It's recommended to weigh the hair on a jeweler’s scale. If scalp hair isn't accessible, a similar quantity of body hair may be used. "Head hair" refers exclusively to scalp hair, while "body hair" encompasses all other hair types (like facial or axillary hair).
Process Overview
The primary laboratory processing stages for a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step, where the sample is logged into the lab's system. This process includes verifying proper sealing and shipping of the sample, assigning a LAN (Laboratory Accessioning Number), and handling any outstanding data entry that wasn't done through an electronic chain of custody.
Screening is a preliminary test for drug presence. Although cost-efficient for excluding drug use in many samples, a positive screen requires confirmation for legal acceptability. Samples with positive screening results need secondary confirmation.
For samples flagged as presumptively positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. During this stage, drugs are isolated from hair at lower concentrations than other methods (like urine or oral fluid); hence, hair drug tests present a significant challenge to execute.
Confirmation of a positive screening is done using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. Every step from Accessioning to Confirmation is overseen according to the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
