Hair testing is increasingly recognized as an effective means of detecting drug and alcohol consumption. The hair captures a long-term record of alcohol and drug usage by embedding biomarkers within the strands of hair as it grows. When hair is sampled near the scalp, it can provide a detection span of up to roughly three months for both alcohol and drugs. The collection process for hair is straightforward, challenging to tamper with, and easy to send.
A hair sample of 1.5 inches, consisting of around 200 strands (approximately the thickness of a #2 pencil), taken closest to the scalp, yields 100mg of hair, which is perfect for screening and confirmation purposes. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is optimal. We suggest weighing the hair using a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair can be collected. References to head hair pertain solely to scalp hair, whereas body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The key phases included in processing a drug test result within a laboratory are Accessioning, Screening, Extraction, and Confirmation.
The Accessioning phase involves the initial steps of incorporating a sample into a lab's system. This phase includes confirming that the sample was appropriately sealed and shipped, assigning it a random LAN (Laboratory Accessioning Number), and performing any additional data entry that was not previously provided by an electronic chain of custody system.
The Screening phase is a preliminary assessment for drugs of abuse. While Screening is an economical approach to exclude drug usage in most samples, a positive result requires confirmation for it to be permissible in legal proceedings. Samples with a presumptive positive result in Screening require a follow-up confirmation.
If a sample shows a presumptive positive in the Screening phase, additional hair is taken from the original sample and prepped for Extraction. In this phase, drugs are extracted from hair at a much lower concentration compared to other methods (such as urine or oral fluid), making hair drug screening a challenging methodology to execute.
Confirmation of any positive result from screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed as necessary prior to confirmation. The full laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair program and the accreditation to ISO / IEC 17025 standards.
