Hair testing is recognized as a significant method for identifying drug and alcohol consumption. Hair encapsulates alcohol and other drug biomarkers within the growing strand, providing a historical record. When gathered close to the scalp, it offers a detection window of up to about three months for alcohol and other drugs. Collecting hair is straightforward, not easily tampered with, and convenient to transport.
A sample measuring 1.5 inches, consisting of approximately 200 hair strands (comparable to a #2 pencil thickness) nearest to the scalp yields 100mg, which is ideal for screening and confirmation procedures. For additional tests like EtG or those exceeding 10 panels, 150mg is advised. Use a jeweler's scale for weighing the specimen. If scalp hair is unavailable, an equivalent quantity of body hair can be collected. By head hair, we specifically refer to scalp hair, while body hair encompasses all other types (such as facial and axillary hair).
Process Overview
The process of laboratory handling of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary processing of a sample into the lab's system. This stage ensures that the sample is correctly sealed and shipped, assigns a Laboratory Accessioning Number (LAN) randomly, and finalizes any necessary data entry absent from an electronic chain of custody system.
Screening is a preliminary assessment to identify drugs of abuse. Although Screening is a cost-efficient means to disqualify drug use in most samples, a positive screen requires confirmation to hold up in court. Any samples possibly positive in Screening necessitate a follow-up confirmation.
Should a sample be deemed presumptively positive during Screening, further hair is extracted from the initial specimen for Extraction. This step involves extracting drugs from hair at concentrations notably lower than other methods (like urine or oral fluid), making hair drug testing one of the most challenging methodologies.
Confirmation of any screening results indicating positivity is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples undergo washing before confirmation as required. The full laboratory process from Accessioning through Confirmation is assessed under both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.
