Hair screening is now recognized as a formidable method for identifying drug and alcohol consumption. Hair captures a comprehensive record of alcohol and drug use by encasing biomarkers in the developing hair fibers. When sampled near the scalp, hair can reveal an approximately three-month window of detection for substances. The collection process is straightforward, with minimal risk of tampering, and it is easily transportable.
A hair sample measuring 1.5 inches, consisting of roughly 200 hairs (comparable in size to a #2 pencil) closest to the scalp, yields 100mg of hair, a prime sample size for analysis and validation. For EtG, supplementary tests, or panels exceeding 10 tests, a 150mg specimen is advised. Using a jeweler's scale for accurate weighing is suggested. Should scalp hair be unobtainable, equivalent body hair may be utilized. References to head hair indicate only scalp hair, while body hair encompasses all other types (such as facial and axillary hair, etc.).
Process Overview
The core laboratory steps for drug testing results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails registering the sample into the laboratory's system. This step ensures the integrity of the sample's seal and its proper shipment, assigns a unique LAN (Laboratory Accessioning Number), and completes additional necessary data entry not available through an electronic chain of custody.
Screening acts as a preliminary check for substances of abuse. Despite its cost-effectiveness at ruling out most drug usage, a positive result requires confirmation to be court-admissible. Samples indicated as positive during Screening mandate further confirmation.
In the presence of a presumptive positive in Screening, additional hair from the initial sample is prepared for Extraction, where substances are derived from hair at significantly lower concentrations than other methodologies (e.g., urine or oral fluid), underscoring the complexity of hair drug testing.
The Confirmation of positive screenings is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples marked as presumptively positive are cleansed as required before confirmation. The entire laboratory protocol, from Accessioning to Confirmation, undergoes review according to CAP (College of American Pathologists) Hair guidelines and accreditation under ISO / IEC 17025 standards.
