Hair testing is regarded as a compelling method for identifying drug and alcohol consumption. Hair captures a prolonged record of substances by holding biomarkers in the fibrous structure of the hair strand as it grows. When sampled near the scalp, hair offers roughly a 3-month window for detecting alcohol and drugs. Hair is straightforward to collect, resistant to tampering, and convenient to transport.
A 1.5-inch section containing about 200 hair strands (around the girth of a #2 pencil) nearest the scalp yields 100mg of hair, which is the preferred sample quantity for testing and verification. For EtG, additional features, and/or analyses beyond 10 panels, 150mg of the specimen is suggested. It is recommended to weigh the specimen using a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be gathered. When mentioning head hair, it specifically means scalp hair only. Body hair pertains to any other type (facial, axillary, etc.).
Process Overview
The critical stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial handling of a sample into a lab’s system. This involves ensuring the sample was appropriately sealed and shipped, allocating a unique LAN (Laboratory Accessioning Number), and completing any additional required data entry not captured by an electronic chain of custody solution.
Screening consists of a preliminary swift evaluation for substances of abuse. Screening is an economical approach to exclude drug use in the majority of samples, but a positive screening requires confirmation to be permissible in legal settings. Any samples showing presumed positive in Screening require a subsequent confirmation.
If a sample is presumed positive during the Screening phase, additional hair is extracted from the initial specimen for Extraction. During this phase, substances are isolated from hair at a lower concentration than other methods (e.g., urine or oral fluids), making hair drug testing the most challenging method to execute.
Verification of any positive screening outcome ensues using GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples undergo washing prior to confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.
