Hair testing is increasingly regarded as an effective approach for detecting drug and alcohol use. Hair captures a long-term record of alcohol and drugs by sequestering biomarkers within the fibers of the hair strand as it grows. When collected near the root, hair offers approximately a 3-month retrospective window for identifying alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch segment of around 200 hair strands (comparable in size to a #2 pencil) close to the root will provide 100mg of hair, which is ideal for both screening and validation. For EtG, additional tests, or panels exceeding 10, 150mg of the sample is advised. We suggest using a jeweler’s scale to measure the sample. Should scalp hair be lacking, an equivalent quantity of body hair may be used. The term "head hair" specifically refers to scalp hair, whereas "body hair" includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial processing of a specimen into a lab’s system. This step involves ensuring the sample was correctly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody system.
Screening provides a preliminary assessment for substances of abuse. While Screening is a cost-effective method to rule out drug use in most samples, a positive screen must be confirmed for legal admittance. Any samples testing presumptively positive during Screening necessitate further confirmation.
If a sample shows a presumptive positive result in the Screening phase, additional hair is extracted from the initial sample and prepped for Extraction. In this phase, substances are isolated from hair at much lower concentrations than in other methods (such as urine or oral fluid), underscoring why hair drug testing is the most complex method to conduct.
Confirmation of any positive screening results is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo a wash before confirmation as required. The comprehensive lab procedure from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.
