Hair analysis is regarded as an effective method for detecting substance and alcohol usage. Hair captures a long-term record of substances by trapping indicators within the strands as they grow. When gathered near the scalp, hair offers an approximately three-month window of detection for both alcohol and drugs. It's straightforward to collect, somewhat challenging to tamper with, and convenient to transport.
A sample of 1.5 inches comprised of approximately 200 hair strands (comparable to a #2 pencil in size) near the scalp will yield 100mg of hair, considered the optimal amount for both screening and confirmation. For EtG, additional assays, and/or tests exceeding 10 panels, a 150mg specimen is advisable. It's suggested to weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, the equivalent quantity of body hair can be collected. When referring to head hair, this specifically means scalp hair. Body hair refers to all other types (facial, axillary, etc.).
Process Overview
The four primary stages in the laboratory analysis of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails inputting a sample into a lab's system. This procedure includes ensuring the sample was properly sealed and transported, allocating a random LAN (Laboratory Accessioning Number), and carrying out any extra data entry not available through an electronic chain of custody system.
Screening involves a preliminary rapid test for substance abuse indicators. It’s a cost-efficient method to eliminate drug use for most samples, though a positive result in Screening necessitates confirmation for court acceptance. Presumptive positives in Screening do require additional verification.
Upon a presumptive positive in the Screening stage, additional hair is extracted from the initial sample and readied for Extraction. Herein, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), which accounts for hair drug testing being among the most complex methodologies.
Confirmation of any positive in Screening is performed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive specimens are cleansed prior to confirmation as required. The entirety of the laboratory process, from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
