Hair tests are increasingly recognized as an effective means for detecting drug and alcohol usage. The structure of hair holds a record of drug and alcohol consumption by capturing biomarkers within the hair's fibers. When hair close to the scalp is gathered, it can offer around a three-month timeframe for detecting alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch sample consisting of about 200 hair strands, approximately the width of a #2 pencil, situated near the scalp, yields 100mg of hair, which is the optimal quantity for screening and analysis. For EtG, additional panels, and/test types exceeding 10 panels, 150mg of hair is suggested. We suggest using a jeweler's scale for measuring the sample. In cases where scalp hair isn't available, substitute with an equivalent amount of body hair. Mention of head hair specifically relates to scalp hair. Body hair includes other types (facial, axillary, etc.).
Process Overview
The primary four phases in processing drug test results in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes inputting a sample into the lab’s system initially. This process entails ensuring the sample was sealed and delivered correctly, allocating a unique LAN (Laboratory Accessioning Number), and performing any missing data entry absent in an electronic chain of custody system.
Screening is an initial rapid assessment for substances of abuse. Screening is an economically efficient method to discount drug use in most samples. However, screens with positive outcomes must be confirmed to be legally valid. Samples presuming positive in Screening warrant a follow-up confirmation.
Should a sample test positive during the Screening phase, additional hair is extracted from the original sample and readied for Extraction. Here, drugs are retrieved from hair at a substantially lower density compared to other techniques (e.g., urine or oral fluid), underscoring the complexity of hair drug testing.
The Confirmation of any result that tested positive in screening is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo cleansing before confirmation if deemed essential. The complete lab procedure from Accessioning to Confirmation undergoes scrutiny under both CAP (College of American Pathologists) Hair designation and the accreditation under ISO / IEC 17025 standards.
