Hair analysis has evolved into a robust method for identifying drug and alcohol consumption. The hair stores a lengthy record of substances by encapsulating biomarkers within the strands as they grow. When collected near the scalp, it offers roughly a 90-day period for detecting drugs and alcohol usage. Collecting hair is straightforward, relatively resistant to tampering, and simple to transport.
A segment of hair measuring 1.5 inches, comprising approximately 200 strands (comparable to a #2 pencil), is collected nearest the scalp to yield 100mg—the preferred quantity for screening and confirmatory analysis. For EtG, additional testing, and/or panel tests exceeding ten, a 150mg sample of hair is advised. It is recommended that the sample be weighed on a jeweler’s scale. In the absence of scalp hair, an equivalent measure of body hair may be used. Mention of head hair pertains specifically to scalp hair, while body hair encompasses all other forms (e.g., facial, axillary).
Procedure Summary
The laboratory process for analyzing a drug test sample traditionally includes four stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning signifies the initial inclusion of a sample into the laboratory framework. Steps include verifying proper sealing and shipping of the sample, issuing an arbitrary LAN (Laboratory Accessioning Number), and completing any extra data inputs not provided through a digital chain of custody system.
Screening entails an early appraisal for drugs of misuse. While Screening serves as an economical means for excluding drug use in most cases, a positive result mandates verification to be legally valid. Presumptive positives from Screening must undergo additional confirmation.
Should a sample test presumptively positive during Screening, further hair is extracted from the specimen for preparation in the Extraction phase. Here, drugs are isolated from hair at concentrations lower than other methods (e.g., urine or oral fluid), thus highlighting the complexity of hair drug testing.
Any positive screens receive Confirmation through GC/MS, GC/MS/MS or LC/MS/MS. Preceding Confirmation, all presumptive positive samples undergo washing as required. The entire lab sequence, from Accessioning to Confirmation, adheres to the CAP (College of American Pathologists) Hair guidelines, alongside ISO / IEC 17025 standards.
