Hair testing has emerged as a significant tool for identifying drug and alcohol usage. It offers an extended history of alcohol and other drugs by capturing biomarkers within the fibers of the growing hair. When taken near the scalp, hair can provide a detection period of up to roughly three months for alcohol and other substances. Hair is easy to collect, somewhat challenging to tamper with, and straightforward to transport.
A sample measuring 1.5 inches with approximately 200 strands of hair (about pencil-thickness) close to the scalp yields 100mg, serving as the optimal sample for screening and verification. For EtG, enhancements, and/or assessments exceeding 10 panels, 150mg of the sample is advisable. We suggest weighing the sample with a jeweler’s scale. If lacking scalp hair, a comparable quantity of body hair is permissible. In discussing head hair, we mean scalp hair exclusively. Body hair comprises all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary processing of a sample into the lab’s system. This stage involves verifying that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not managed by an electronic chain of custody system.
Screening represents an initial rapid check for drugs of abuse. While Screening is cost-efficient and suitable for eliminating drug use recognition in most samples, a positive screen must be confirmed to be legally valid. Samples that are presumptively positive in Screening necessitate a secondary verification.
If a sample is presumptively positive during Screening, further hair is extracted from the initial sample, preparing it for Extraction. In this phase, drugs are extracted from hair at much lower concentrations than in other methodologies (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.
Verification of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All presumptive positive samples undergo washing before confirmation if necessary. The complete laboratory process, from Accessioning to Confirmation, complies with both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
