Hair analysis is now recognized as a robust method for detecting the consumption of alcohol and drugs. This technique captures biomarkers within the hair strand fibers, providing a detailed history of usage over an extended period. Sampled near the scalp, hair offers detection capabilities for drug and alcohol usage for nearly three months. Hair collection is straightforward, with minimal opportunity for tampering, and is convenient for transportation.
The ideal sample for both screening and confirmation is a 1.5-inch segment consisting of roughly 200 hair strands (approximating the thickness of a #2 pencil), yielding 100mg of hair. For EtG, additional panels, or tests exceeding 10 panels, a 150mg sample is advisable. We suggest using a jeweler's scale for weighing the sample. In cases where scalp hair isn't accessible, an equivalent quantity of body hair can be used. Note that "head hair" specifically pertains to scalp hair, while "body hair" encompasses all other varieties (such as facial and axillary hair).
Process Overview
The laboratory processing of a drug test is typically divided into four critical stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample integrates into the laboratory system, ensuring the sample was securely shipped and identifying it with a unique LAN (Laboratory Accessioning Number). Any supplementary data entry not facilitated by an electronic custody system is also performed here.
Screening is a preliminary examination for potential drug use. While it is a cost-saving measure for dismissing drug usage in most samples, a positive result from Screening needs further verification to be legally valid. Positive results from Screening necessitate additional confirmation steps.
Should the Screening phase suggest positive findings, further analysis using more hair from the original sample is conducted during Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than other methods (such as urine or oral fluid), highlighting the complexity of hair drug screening.
Confirmation of any positive Screening outcomes is completed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Pre-confirmation, any samples indicating positive results are cleansed as necessary. The entire specimen handling from Accessioning to Confirmation is evaluated following both the CAP (College of American Pathologists) Hair criteria and ISO/IEC 17025 accreditation standards.
