Hair analysis is now recognized as an effective method for detecting drug and alcohol consumption. This technique offers a comprehensive historical overview, as hair strands trap biomarkers within their fibers. When hair is gathered close to the scalp, it can reveal drug or alcohol use over approximately a three-month period. Hair collection is straightforward, challenging to tamper with, and easy to transport.
A sample consisting of 1.5 inches of about 200 strands (roughly the thickness of a #2 pencil) from near the scalp provides 100mg of hair, which is perfect for both initial screening and confirmation. For EtG testing, additional requirements, and/or tests exceeding 10 panels, a sample weighing 150mg is advised. It's suggested to weigh the sample with a jeweler’s scale. If scalp hair isn't accessible, a comparable amount of body hair may be gathered. The term "head hair" specifically pertains to scalp hair only, while "body hair" includes all other types such as facial or axillary hair.
Process Overview
The laboratory processing of a drug test involves four core steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the process of initially logging a sample into the lab's system. This step involves ensuring the sample's proper sealing and shipping, generating a unique LAN (Laboratory Accessioning Number), and completing any missing data not provided by an electronic chain of custody system.
Screening is an initial rapid assessment for drug presence. Although this step is efficient for ruling out drug use in most cases, any positive result requires further confirmation for court admissibility. Samples with presumptive positives in Screening need additional confirmation.
In cases where Screening suggests a positive result, more hair is retrieved from the original sample for further Extraction. During Extraction, substances are removed from hair at significantly lower concentrations compared to other methods such as urine or oral fluid, highlighting the complexity of hair drug screening.
Confirmation of any preliminary positive outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptively positive samples undergo washing before confirmation as necessary. The whole laboratory workflow, from Accessioning to Confirmation, is critically reviewed and accredited under the CAP (College of American Pathologists) Hair designation and follows ISO / IEC 17025 norms.
