Hair analysis is now regarded as a robust method for identifying drug and alcohol consumption. Hair can showcase extended usage of substances as it captures biomarkers within the strands as hair grows. When hair is sampled near the scalp, it might reflect drug and alcohol activity for roughly three months. Collecting hair is easy to perform, somewhat resistant to tampering, and convenient to transport.
For effective analysis, a sample of 1.5 inches featuring around 200 hair strands (similar in size to a #2 pencil) next to the scalp will yield 100mg, making it a perfect specimen for analysis and validation. For EtG evaluations, additional substances, or tests exceeding 10 panels, 150mg is preferred. Using a jeweler's scale is advised for precise measurement. In cases where scalp hair isn't an option, an equal mass of body hair may be gathered. Mentions of head hair specifically refer to scalp hair, while body hair indicates all other types (such as facial or axillary hair).
Overview of the Process
The four central phases in the lab processing of drug testing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails initially handling a sample within a lab's framework. This step ensures the integrity of the sample regarding sealing and shipping, assigns a unique LAN (Laboratory Accessioning Number), and completes additional data entries that might not be present via an electronic custody process.
Screening provides an initial assessment for substance misuse. Although it is cost-efficient and can eliminate drug use suspicions for most cases, a positive indication requires verification to be legally accepted. Samples that screen positively need further confirmed testing.
A presumptive positive result during Screening prompts the extraction of more hair from the first sample for the Extraction step. Here, substances are drawn from hair, albeit at a lower level of concentration compared to other methods (e.g., urine or saliva), which explains why hair analysis is more complex.
Positive screening outcomes are substantiated using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Samples identified as presumptive positives undergo a cleaning stage before confirmation. From Accessioning to Confirmation, each step is cross-checked according to both CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.
