Hair analysis is now recognized as an effective means for identifying alcohol and drug consumption. Hair captures a prolonged record of substance use by embedding biomarkers within the fibers of the hair as it grows. When sampled near the scalp, hair offers a detection period of up to approximately three months for both alcohol and drugs. The collection process for hair is straightforward, it is relatively challenging to tamper with, and easy to transport.
A 1.5-inch section comprising approximately 200 hair strands (roughly equivalent to a #2 pencil) located nearest to the scalp will yield 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG, additional requirements, and/or tests exceeding 10 panels, a sample of 150mg is preferred. We advise using a jeweler's scale to weigh the sample. If hair from the scalp is not accessible, an equivalent amount of body hair can be obtained. When we mention head hair, it specifically refers to scalp hair only. Body hair pertains to all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test result encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage involving the integration of a sample into a lab's system. This step includes verifying that the sample is appropriately sealed and dispatched, assigning it a random LAN (Laboratory Accessioning Number), and completing any supplementary data input not provided via an electronic chain of custody method.
Screening provides a preliminary rapid assessment for substances of abuse. Although Screening is a cost-effective way to exclude drug use in most samples, a positive result requires confirmation for court admissibility. Samples that exhibit a presumptive positive during Screening need a secondary confirmation.
Should a sample show a presumptive positive during the Screening phase, additional hair is extracted from the original sample and readied for Extraction. In this process, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening a challenging methodology to execute.
Confirmation of any positive screening outcome is carried out by means of GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positivity are cleansed before undergoing confirmation, as required. The entire lab procedure from Accessioning to Confirmation undergoes review according to both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: While commonly called "hair follicle tests", the examination itself is performed on the hair strand, not the hair follicle beneath the scalp.
