Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of substance use by embedding biomarkers within the fibers of the developing hair strand. When gathered near the scalp, hair can reveal a detection window 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 1.5-inch portion comprising about 200 hair strands (comparable to the diameter of a #2 pencil) nearest the scalp will yield 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, additional tests, and/or panels above ten, 150mg of the sample is advisable. Using a jeweler's scale for weighing the specimen is recommended. In the absence of scalp hair, a commensurate quantity of body hair may be used. "Head hair" exclusively pertains to scalp hair. Body hair includes all other types (facial, underarm, etc.).
Process Overview
The four primary steps in laboratory processing of drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary handling of a sample into a lab's system. This step ensures the sample was securely sealed and appropriately shipped, assigns a random Laboratory Accessioning Number (LAN), and accomplishes any supplementary data entry not captured by an electronic chain of custody system.
Screening entails an initial rapid assessment for substances of abuse. While Screening offers a cost-efficient means to eliminate drug use in most samples, a positive result necessitates confirmation for court admissibility. Any samples that test presumptively positive during Screening require secondary confirmation.
When a sample tests presumptively positive in Screening, additional hair is extracted from the original sample for preparation in Extraction. This phase extracts drugs from hair at a significantly lower concentration than other techniques (e.g., urine or oral fluid), underscoring hair drug screening's complexity in execution.
Confirmation of any positive screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples undergo washing as needed. The complete lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.
