Hair testing is recognized as a robust method for identifying usage of drugs and alcohol. Hair retains a long-term use record of substances by capturing biomarkers within the hair fiber. Collected near the scalp, it can offer a detection span of up to three months for both alcohol and drugs. The collection process is straightforward, harder to tamper with, and easy to transport.
Cutting a 1.5-inch length of about 200 hair strands (roughly a #2 pencil's diameter) closest to the scalp yields approximately 100mg of hair, which is optimal for screening and confirmation tests. For EtG, additional testing, or panels over 10, 150mg of the sample is advised. It is suggested to measure the sample on a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair may be used. The term head hair specifically refers to scalp hair. In contrast, body hair encompasses all other hair types (such as facial or axillary).
Process Overview
The primary categories in the laboratory's drug test processing procedure are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial entry of a sample into a laboratory's protocol. This includes ensuring the sample was properly sealed and delivered, assigning it a unique LAN (Laboratory Accessioning Number), and inputting any remaining data not captured by an electronic custody system.
Screening is a preliminary and quick assessment for substances of misuse. It efficiently eliminates most samples from further testing but requires any positive screens to be validated for legal acceptance. Any samples testing positive in Screening necessitate subsequent confirmation.
For samples that test positive in Screening, further hair is utilized from the existing sample and prepared for Extraction. In this stage, drugs are extracted from hair at lower concentrations than in other sample types (e.g., urine or oral fluids), making hair drug screening one of the more complex methodologies to perform.
Confirmation of any positive screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with initial positive results are cleaned before confirming as required. The laboratory process, from Accessioning to Confirmation, is evaluated following both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation standards.
