Hair testing has emerged as an effective means to identify drug and alcohol consumption. Hair strands encapsulate long-term biomarkers within their fibers, offering a detailed history of alcohol and drug use. When sampling close to the scalp, hair can reveal drug and alcohol presence within a time frame of about three months. The collection process is straightforward, the samples are resistant to tampering, and they are easy to transport.
Taking a 1.5-inch sample with approximately 200 hair strands (similar in width to a #2 pencil) nearest the scalp provides 100mg of hair, which is considered ideal for both screening and confirmation processes. For EtG, extended panels, and/or tests exceeding ten panels, a sample of 150mg is advisable. It is suggested to measure the hair on a jeweler’s scale. If scalp hair is inaccessible, an equivalent quantity of body hair can be obtained. References to head hair pertain solely to scalp hair, while body hair encompasses all other types (facial hair, armpits, etc.).
Process Overview
The process of laboratory evaluation for drug tests involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the introduction of a sample into a laboratory’s framework. This step involves checking the sample's proper sealing and shipment, allocating a random LAN (Laboratory Accessioning Number), and completing any missing details not included in an electronic chain of custody system.
Screening offers an initial assessment for drug abuse. While Screening economically eliminates drug use in many cases, a positive result must be confirmed for legal credibility. Samples with presumptive positive findings in Screening warrant a further confirmation test.
In cases where Screening suggests a positive result, additional hair from the initial sample undergoes preparation for Extraction. This stage extracts drugs from hair, presenting a lower concentration than seen in other methods, such as urine or oral fluid, highlighting that hair drug testing is notably challenging.
Confirmation of any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positives are washed before confirmation if necessary. The entirety of lab processes from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair program as well as ISO / IEC 17025 accreditation standards.
