Hair analysis is now recognized as an effective method for detecting alcohol and drug consumption. Hair retains a comprehensive record of alcohol and drug intake by embedding biomarkers within the strands of hair as they grow. When hair is cut near the scalp, it can reflect up to a 3-month timeframe for detecting alcohol and drugs. The collection process is straightforward, tampering is difficult, and it is convenient to send off for testing.
A hair sample measuring 1.5 inches, consisting of about 200 strands (roughly the size of a #2 pencil) from near the scalp, will weigh 100mg, an optimal quantity for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a sample weighing 150mg is advised. It's best to use a jeweler's scale for weighing the sample. If scalp hair is unavailable, a comparable quantity of body hair may be utilized. "Head hair" pertains exclusively to scalp hair, while "body hair" encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The procedure for laboratory testing of drug samples consists of four essential phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary handling of a sample within a laboratory's framework. This phase includes ensuring the sample was correctly sealed and shipped, allocating a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent from an electronic chain of custody system.
Screening entails an initial cursory examination for substances of abuse. While Screening provides an economical approach to exclude drug use in the majority of samples, a positive screen must undergo confirmation to be considered valid in legal proceedings. Samples yielding a presumptive positive result during Screening will require further confirmation.
If a sample reflects a presumptive positive result during Screening, additional hair from the original specimen is readied for Extraction. During this stage, drugs are extracted from hair at significantly lower concentrations compared to other methodologies (e.g., urine or oral fluid), attributing to the complexity of hair drug testing.
Confirmation of any positive screening outcomes is executed via GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing prior to confirmation as necessary. The comprehensive laboratory sequence from Accessioning to Confirmation is conducted in compliance with both the CAP (College of American Pathologists) Hair designation and certification to ISO / IEC 17025 standards.
