Hair analysis has become recognized as an effective instrument for identifying drug and alcohol intake. Hair strands capture biomarkers in their fibers, offering a prolonged overview of alcohol and drug usage. When taken near the scalp, hair can offer about a 3-month observation span for alcohol and other drugs. Hair is easy to collect, not easily tampered with, and convenient to transport.
A 1.5-inch portion of roughly 200 hair strands (approximately the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is optimal for testing and verification. For EtG, additional tests, and/or panels over 10, a 150mg sample is advised. We suggest utilizing a jeweler's scale to weigh the sample. In the absence of scalp hair, a similar quantity of body hair is acceptable. "Head hair" specifically pertains to scalp hair, whereas "body hair" covers all other variations (such as facial, axillary, etc.).
Process Overview
The primary stages in a lab for processing a drug test result include Accessioning, Screening, Extraction, and Verification.
Accessioning involves incorporating a sample into a lab’s system. This step verifies proper sealing and shipment of the sample, allocates a LAN (Laboratory Accessioning Number), and completes any extra data entry omitted by an electronic chain of custody framework.
Screening is a rapid initial check for drug abuse. Though Screening efficiently rules out drug usage for most samples, a positive result needs confirmation for legal validity. Samples with a suspected positive Screening result require further confirmation.
Should a sample indicate a positive outcome during Screening, additional hair is taken from the initial sample ready for Extraction. Here, drugs are extracted from hair at notably lower concentrations than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.
Any positive Screening results undergo Confirmation utilizing GC/MS, GC/MS/MS, or LC/MS/MS. All samples with suspected positive results are cleaned before Confirmation as necessary. The full lab process from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
