Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. Hair offers an extended history of alcohol and drug exposure by trapping biomarkers within the growing hair's fibers. When sourced near the scalp, hair can reveal up to an estimated 3-month detection timeline for drugs and alcohol. It's easy to collect, resistant to tampering, and straightforward to mail.
A cluster of 1.5 inches consisting of about 200 hair strands (similar in size to a #2 pencil) near the scalp yields 100mg of hair, the optimal sample for initial and confirmatory testing. For EtG, additional analyses, and/or tests exceeding 10 panels, a 150mg sample is advised. We advocate using a jeweler’s scale to weigh the sample. In the absence of scalp hair, a corresponding amount of body hair is acceptable. By head hair, we refer solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory procedures for processing a drug test result entail four core stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the preliminary processing of a sample into a lab’s database. This involves confirming that the sample is properly sealed and shipped, generating a unique LAN (Laboratory Accessioning Number), and completing any ancillary data entry absent in an electronic chain of custody set-up.
Screening signifies a preliminary rapid detection for drug abuse. Though Screening is an economical method to exclude drug presence in most samples, a positive result must be validated for legal admissibility. Samples that exhibit a presumptive positive in Screening mandate subsequent confirmation.
Should a sample show a presumptive positive during Screening, additional hair is extracted from the original sample and readied for Extraction. Here, drugs are separated from hair at significantly lower concentrations compared to alternative methods (such as urine or oral fluid), making hair drug analysis the most complex method to execute.
Positive screening confirmations are executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are cleansed before confirmation as required. The complete lab procedure from Accessioning to Confirmation is scrutinized under the authority of both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
