Hair testing is increasingly viewed as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and substance use by embedding biomarkers in the growing hair fibers. When sampled near the scalp, hair can reveal drug and alcohol usage for up to approximately 3 months. It's easy to collect, relatively tamper-resistant, and convenient to transport.
A sample measuring 1.5 inches and containing around 200 hair strands (roughly #2 pencil thickness) near the scalp will yield 100mg of hair, which is optimal for screening and confirmation purposes. For EtG, additional tests, or panels exceeding 10, a specimen amount of 150mg is suggested. It's advisable to use a jeweler’s scale to weigh the sample. If scalp hair can’t be collected, an equivalent quantity of body hair may be used. "Head hair" specifically refers to scalp hair, whereas "body hair" includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary handling of a sample within a laboratory’s framework. This step ensures that the sample was properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes supplemental data entry not included by an electronic chain of custody system.
Screening is an initial evaluation for substances of abuse. Although Screening is an economical approach to exclude drug use in most samples, any positive findings must be verified to be permissible legally. Samples with presumptive positive results in Screening mandate further confirmation.
Should a sample yield a presumptive positive in the Screening phase, additional hair is sourced from the original sample for the Extraction process. Here, drugs are isolated from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), underlining the complexity of hair drug screening.
Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are washed before confirmation as required. The complete laboratory process, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
