Hair analysis is recognized as an effective instrument for identifying substance use, including drugs and alcohol. Hair retains biomarkers with its fibers over time, offering a prolonged history of usage. When trimmed near the scalp, hair can yield a detection period of up to three months for substances like alcohol. Collection is straightforward, tampering is relatively challenging, and the specimen is simple to transport.
A 1.5-inch hair segment consisting of roughly 200 strands near the scalp, mirroring the thickness of a #2 pencil, yields 100mg—ideal for both screening and confirmation. For EtG, additional screens, or tests beyond 10 panels, 150mg is advisable. Precision weighing of the hair using a jeweler’s scale is recommended. In cases where scalp hair is unavailable, equivalent body hair may be gathered. Head hair is specifically scalp hair, while body hair encompasses all other kinds (facial, underarm, etc.).
Process Overview
The laboratory handling of a drug test involves four essential phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning handles the initial sample processing into the lab’s inventory, which verifies proper sealing and shipment, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional required data absent from an electronic chain of custody.
Screening serves as an initial assessment for substance abuse. While cost-effective for negating drug usage in most samples, a positive result in Screening must undergo confirmation for legal validity. Samples flagged as presumptively positive during Screening necessitate further confirmation.
When a sample tests positive at the Screening stage, additional hair is taken from the primary sample for Extraction. Drugs are isolated from hair in significantly lower concentrations compared to other methods (like urine or oral fluid), contributing to the complexity of hair drug analysis.
Positive screening findings undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Samples identified as presumptive positives are cleansed before confirmation if necessary. The comprehensive lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation guidelines.
