Considered a potent method, hair testing efficiently identifies drug and alcohol consumption. Hair accumulates long-term evidence of substances by encapsulating biomarkers within hair strands as they grow. When hair is sourced near the scalp, it provides a detection period that lasts up to three months for alcohol and other drugs. Collecting hair is straightforward, less vulnerable to tampering, and convenient for transport.
A sample measuring 1.5 inches from approximately 200 hair strands (comparable to a #2 pencil's width), gathered closest to the scalp, delivers 100mg of hair—ideal for both screening and confirmation. For EtG, additional tests, or those exceeding 10 panels, a 150mg sample is advised. Utilizing a jeweler’s scale for weighing is suggested. In case scalp hair is unavailable, a comparable amount of body hair may be collected. Head hair refers exclusively to scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory handling of a drug test result encompasses four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary integration of a sample into the laboratory system. This step ensures the sample was correctly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry missing from an electronic chain of custody system.
Screening represents an initial, expeditious examination for drug abuse. As a cost-efficient method, Screening screens out drugs in most samples; however, a positive outcome requires confirmation for legal admissibility. Presumptive positive samples from Screening necessitate subsequent confirmation.
Should Screening suggest a sample is positive, additional hair from the initial sample is subjected to Extraction. This stage extracts drugs from hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), making hair drug testing a particularly challenging methodology.
Any positive screening result is confirmed with GC/MS, GC/MS/MS, or LC/MS/MS. Confirmation involves washing presumptive positive samples when needed. The entire lab process, from Accessioning to Confirmation, is reviewed under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
