Hair analysis is now recognized as an effective means to detect alcohol and drug consumption. By capturing biomarkers within the fibers of the growing strand, hair offers a comprehensive historical view of drug and alcohol use. When collected from the scalp, hair can reveal drug and alcohol use spanning roughly three months. The collection of hair is straightforward, less prone to tampering, and easy to transport.
A 1.5-inch sample consisting of approximately 200 strands (comparable to a #2 pencil) closest to the scalp will amount to 100mg, which is the optimal quantity for both screening and confirmatory tests. For EtG, additional tests, and/or panels exceeding ten, a 150mg sample is advised. Utilizing a jeweler's scale to measure the specimen is recommended. In the absence of scalp hair, an equivalent quantity of body hair may be obtained. References to head hair imply scalp hair specifically. "Body hair" encompasses all non-scalp hair types (e.g., facial, axillary).
Process Overview
The laboratory procedure for processing a drug test result comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves incorporating a sample into a laboratory’s framework. This stage includes ensuring the sample was correctly sealed and dispatched, allocating a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry missing from an electronic custody chain system.
Screening is a preliminary assessment for illicit substances. While cost-effective for excluding drug use in most samples, positive results require confirmation for legal acceptability. Any Screening-phase samples that are tentatively positive need subsequent validation.
Should a sample test tentatively positive during Screening, additional hair is extracted from the initial sample and set for Extraction. At this stage, drugs are extracted from hair at a significantly reduced concentration compared to other methods (such as urine or oral fluid), making hair drug screening the most challenging method to conduct.
Confirmation of any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. From Accessioning to Confirmation, each laboratory stage is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
