Hair analysis is recognized as an effective method for identifying drug and alcohol usage. The hair retains a long-term account of alcohol and other substances by encapsulating biomarkers within the fibers of the developing hair strand. When collected near the scalp, hair can offer a detection timeframe for alcohol and other drugs that extends to roughly 3 months. Hair is straightforward to gather, not easily tampered with, and convenient to transport.
A sample measuring 1.5 inches, with around 200 hair strands (akin to the size of a #2 pencil) closest to the scalp, yields 100mg of hair, which is the ideal sample size for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a 150mg specimen is advised. It is best to weigh the specimen using a jeweler’s scale. If scalp hair cannot be obtained, a comparable amount of body hair may be used. References to head hair pertain specifically to scalp hair, whereas body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four essential steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the process begins with integrating a sample into a laboratory’s workflow. This process verifies the sample's proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and involves completing any additional data entry required that was not provided by an electronic chain of custody system.
Screening involves conducting an initial rapid examination for substances of abuse. While Screening is an economical method to exclude drug use in most samples, a positive screening result requires confirmation to be admissible in legal proceedings. Any samples with a presumptive positive result in Screening necessitate further confirmation.
Should a sample exhibit a presumptive positive in Screening, more hair is extracted from the initial sample and prepared for Extraction. In this stage, drugs are extracted from hair at a considerably lower concentration than in other methods (e.g., urine or oral fluid), hence hair drug screening poses the greatest challenge in execution.
Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples are cleansed before Confirmation as needed. The entire laboratory process from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and accredited in compliance with ISO / IEC 17025 standards.
