Hair analysis is now regarded as a robust method for identifying alcohol and drug consumption. Hair can capture a timeline of substance use since biomarkers are embedded in the fibers as the hair grows. Acquired near the scalp, hair can reveal a period of approximately three months for detecting drug and alcohol usage. Collection of hair is straightforward, hard to tamper with, and convenient to mail.
A sample that is 1.5 inches long, comprising approximately 200 hair strands (comparable to a #2 pencil), nearest to the scalp equates to 100mg of hair, which is the standard sample size for screening and verification. For tests like EtG, add-ons, and those exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale to weigh the specimen is suggested. In cases where scalp hair cannot be obtained, an equivalent volume of body hair may be used. When we mention head hair, we are specifically referring to scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The processing of drug test results in laboratories encompasses four primary procedures: Accessioning, Screening, Extraction, and Confirmation.
Accessioning deals with the initial handling of a sample within a lab’s framework. This stage includes confirming that the sample was correctly sealed and dispatched, assigning a random Laboratory Accessioning Number (LAN), and recording additional data that may be absent from an electronic chain of custody system.
Screening entails a preliminary rapid assessment for drugs of abuse. While Screening serves as a budget-friendly method to dismiss drug consumption in most cases, a positive result requires validation to be accepted in legal proceedings. Samples that test presumptively positive at the Screening stage require a secondary corroboration.
Upon receiving a presumptive positive at Screening, further hair is extracted from the initial sample and is set for Extraction. Here, drugs are isolated from the hair at significantly lower concentrations than alternative methods (e.g., urine or oral fluid), thus making hair drug analysis the most challenging methodology to execute.
GC/MS, GC/MS/MS, or LC/MS/MS techniques are used to confirm any positive screenings. Samples with presumptive positive results are cleansed preliminarily as needed before confirmation. The complete laboratory workflow, from Accessioning through to Confirmation, is audited under the College of American Pathologists (CAP) Hair designation and certified to ISO / IEC 17025 criteria.
