Hair analysis has emerged as an effective method for identifying substance and alcohol consumption. Hair fibers capture biomarkers over time, offering a long-term record of alcohol and drug usage. When hair is collected from close to the scalp, it can reveal drug and alcohol presence over a period of up to three months. Hair is straightforward to gather, relatively resistant to tampering, and simple to transport.
A 1.5-inch segment consisting of roughly 200 hair strands (comparable in size to a #2 pencil) taken nearest to the scalp will yield 100mg of hair, the optimal amount for testing and validation. It is advised to use 150mg for EtG, additional substances, and tests exceeding 10 panels. Utilize a jeweler’s scale for precise specimen measurement. Should scalp hair be inaccessible, an equivalent volume of body hair can be obtained. "Head hair" pertains to scalp hair exclusively, while "body hair" encompasses all other forms such as facial and axillary hair.
Process Overview
The laboratory processing of a drug test comprises four primary phases: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample is initially incorporated into the lab’s system. This phase includes ensuring the sample was sealed and transmitted correctly, assigning a non-sequential LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody protocol.
Screening entails a preliminary check for illicit substances. While Screening is an economical method to eliminate drug presence in most samples, any positive outcomes necessitate validation in order to withstand judicial scrutiny. Samples testing positive during Screening demand a secondary confirmation.
When a sample tests positive in the Screening phase, additional hair is extracted from the original sample and processed for Extraction. During Extraction, drugs are isolated from hair at a significantly reduced concentration in comparison to alternative methods (e.g., urine or saliva), rendering hair drug testing the most intricate procedure to execute.
Positive Screening findings undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed if necessary prior to Confirmation. The complete lab procedure, from Accessioning through Confirmation, is scrutinized under both CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.
