Hair testing has emerged as a potent means for identifying drug and alcohol consumption. Hair offers a prolonged history of alcohol and other drugs by encapsulating biomarkers within the fibers of the hair strand as it grows. Collected near the scalp, hair can yield a detection span of nearly three months for alcohol and other substances. Hair is straightforward to collect, relatively hard to adulterate, and simple to transport.
A sample of 1.5 inches, comprising approximately 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp, will provide 100mg of hair, the preferred amount for screening and confirmation. For EtG, add-ons, and assays exceeding 10 panels, a specimen of 150mg is advisable. We advocate weighing the specimen using a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair may be gathered. “Head hair†signifies scalp hair exclusively, while “body hair†encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test outcome comprises four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary processing of a sample into the laboratory's system. This includes confirming that the sample was properly sealed and sent, allocating a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry not encompassed by an electronic chain of custody system.
Screening involves an initial swift inspection for drugs of abuse. Though Screening is a budget-friendly technique to exclude drug consumption in most samples, a positive screen necessitates confirmation to be accepted in legal scenarios. Presumptively positive samples in Screening mandate a subsequent confirmation.
Should a sample test presumptively positive in the Screening phase, additional hair is extracted from the initial specimen and readied for Extraction. In this phase, drugs are extracted from hair at a considerably lower concentration than in other techniques (e.g., urine or oral fluid), which renders hair drug screening the most challenging methodology to execute.
A positive screening result is confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing prior to confirmation as required. The entire laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
