Hair analysis is now recognized as an effective method for detecting drug and alcohol consumption. Hair captures a long-term record of these substances by retaining biomarkers within the structure of the growing hair shaft. When collected near the scalp, hair can offer a detection period of up to about three months for alcohol and other substances. Hair collection is straightforward, relatively tamper-resistant, and easily transportable.
A sample size of 1.5 inches containing around 200 strands (approximately the width of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimum quantity for screening and verification. For EtG, additional analyses, and/or tests surpassing 10 panels, a 150mg sample is advised. It's advisable to use a jeweler’s scale for weighing the sample. If scalp hair isn’t an option, a comparable amount of body hair can be used. By head hair, we specifically mean scalp hair. 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 stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a lab’s system. This step includes ensuring the sample is sealed and transported correctly, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any additional data entry absent in an electronic chain of custody setup.
Screening provides an initial rapid evaluation for drugs of abuse. Screening is cost-efficient for excluding drug use in the majority of samples, yet a positive result necessitates confirmation to hold up in a legal setting. Samples that present presumptively positive in Screening require additional confirmation.
When a sample receives a presumptively positive result at the Screening stage, more hair is extracted from the primary sample and readied for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), which is why hair drug screening poses the greatest challenge to accomplish.
Final confirmation of any positive screening result is executed via GC/MS, GC/MS/MS or LC/MS/MS. As needed, any presumptive positive samples are cleansed before confirmation. The completion of the laboratory process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair classification and in accordance with ISO / IEC 17025 accreditation.
