Hair analysis is increasingly recognized as an effective method for uncovering alcohol and drug usage. Hair captures a historical record of substances by embedding biomarkers within the hair strand's fibers as it grows. When sourced close to the scalp, hair can reveal alcohol and drug use for up to roughly three months. Collecting hair samples is straightforward, tampering is relatively challenging, and shipping is convenient.
A 1.5-inch segment consisting of about 200 hair strands (the diameter of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal amount for both screening and confirmation processes. For EtG, additional tests, and those beyond 10 panels, it's advised to use 150mg of the sample. We suggest weighing the hair using a jeweler’s scale. If scalp hair isn't available, a comparable amount of body hair is acceptable. "Head hair" refers exclusively to scalp hair, while "body hair" encompasses all other types (such as facial and axillary hair).
Process Overview
Key steps in the lab handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary treatment of a sample within a lab's procedures. This process checks for proper sealing and shipment of the sample, assigns a unique LAN (Laboratory Accessioning Number), and inputs any remaining data that an electronic chain of custody system doesn’t provide.
Screening conducts an initial swift review for substances of abuse. Although Screening is economical and eliminates drug use in most samples, a positive result must undergo confirmation to be valid in legal settings. Samples that yield a presumptive positive result during Screening necessitate subsequent confirmation.
When a sample tests presumptively positive during Screening, additional hair from the original sample is utilized for Extraction. In this phase, drugs are retrieved from hair at a much lower concentration than with other methods (such as urine or oral fluid), explaining why hair drug screening remains a challenging methodology to conduct.
GC/MS, GC/MS/MS, or LC/MS/MS are employed for the Confirmation of positive screening outcomes. All presumptive positive specimens are cleansed before confirmation if needed. The whole laboratory procedure from Accessioning to Confirmation is overseen under the CAP (College of American Pathologists) Hair designation and the accreditation to ISO/IEC 17025 benchmarks.
