The assessment of hair samples has emerged as an effective measure for identifying the consumption of drugs and alcohol. The structure of the hair embeds indicators of drug and alcohol use along the strands as it grows. When collected close to the scalp, hair can provide a time frame of up to three months for the identification of substance use. Hair is easy to gather, not easily tampered with, and simple to send.
A hair sample measuring 1.5 inches, containing about 200 strands (similar to a #2 pencil's thickness), closest to the scalp generates 100mg of hair, which is suitable for analysis and verification. For evaluations involving EtG, additional panels, or more than 10 panels, a sample weighing 150mg is advised. A jeweler’s scale is suggested for weighing the sample. If head hair isn't accessible, an equivalent amount of body hair can be used. When mentioning head hair, it exclusively means scalp hair. The term body hair pertains to all other types of hair (like facial, underarm, etc.).
Process Overview
The laboratory analysis of a drug test outcome comprises four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning engages in the primary handling of a sample within a lab's workflow. This process involves confirming that the sample was properly sealed and delivered, designating a unique LAN (Laboratory Accessioning Number), and fulfilling any additional data recording that an electronic chain of custody system may not cover.
Screening entails an initial quick evaluation for drugs of abuse. Though Screening is an economical approach to exclude drug consumption in most samples, a positive screening result mandates verification to be credible in court. Any samples with a preliminary positive result in Screening require further confirmation.
If a sample shows a presumptive positive result during Screening, additional hair is extracted from the original sample and readied for Extraction. This step involves separating drugs from hair at a notably lower concentration compared to other methods (like urine or saliva tests), which is why hair drug evaluation is the most challenging method to execute.
Verification of any positive screening outcome is performed using GC/MS, GC/MS/MS or LC/MS/MS. Before confirmation, all initial positive samples are cleansed as necessary. The entire laboratory procedure from Accessioning to Confirmation is conducted under the CAP (College of American Pathologists) Hair designation and in compliance with ISO / IEC 17025 guidelines.
