Recognized as a potent method for identifying drug and alcohol consumption, hair testing captures a comprehensive timeline of substance use by embedding biomarkers within the hair's fibers as it grows. When collected near the scalp, hair can present up to a 90-day detection timeframe for alcohol and drugs. The collection process is straightforward, modification-resistant, and easy to transport.
Taking a sample of 1.5 inches with roughly 200 hair strands (akin to the thickness of a #2 pencil) nearest the scalp ensures a 100mg hair sample, which is ideal for both screening and confirmation. For EtG, additional testing, or panels exceeding 10, a 150mg specimen is advised. It's recommended to weigh the specimen on a jeweler's scale. If scalp hair isn't accessible, an equivalent amount of body hair can be used. "Head hair" refers specifically to scalp hair, while "body hair" encompasses all other hair (e.g., facial, axillary).
Process Overview
The main procedures in laboratory analysis of drug test samples include Accessioning, Screening, Extraction, and Confirmation.
Accessioning processes a sample into a laboratory system by checking whether it's been sealed and shipped correctly, assigning a unique LAN (Laboratory Accessioning Number), and performing any necessary data entry missing from an electronic chain of custody.
Screening provides an initial assessment for substances of abuse. While screening is a cost-efficient method to potentially exclude drug use, any positive results require further confirmation to hold up in court. Samples with suspected positive results in Screening need additional validation.
Once a sample tests positive during Screening, additional hair is extracted from the initial sample and readied for Extraction. Here, substances are extracted from the hair at lower concentrations compared to other methods (e.g., urine or oral fluids), making hair drug testing the most challenging methodology.
For Confirmation, any positive screening outcome is verified via GC/MS, GC/MS/MS, or LC/MS/MS. All suspected positive samples are cleansed before confirmation as necessary. The entire laboratory sequence from Accessioning to Confirmation is conducted in line with both the CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.
