Hair analysis is recognized as an effective instrument for uncovering drug and alcohol consumption. The hair captures a prolonged record of substances by embedding biomarkers within the fibers of growing hair strands. When taken nearest to the scalp, hair can offer up to a 90-day detection span for both alcohol and other substances. Its collection is straightforward, tampering is challenging, and it can be easily transported.
An ideal specimen consists of a 1.5-inch length comprising approximately 200 hair strands (about the diameter of a #2 pencil) closest to the scalp, yielding 100mg of hair for screening and validation purposes. For EtG, supplementary tests, and/or panels exceeding 10, it is advisable to supply 150mg. Using a jeweler’s scale to measure the specimen is suggested. Should scalp hair be inaccessible, a comparable amount of body hair can be gathered. References to head hair strictly denote scalp hair, while body hair pertains to all non-scalp types (facial, axillary, etc.).
Process Overview
The laboratory workflow for drug test determination encompasses four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial integration of a sample into a lab's system, ensuring proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and filling out any data entries absent from an electronic chain of custody.
Screening involves a preliminary rapid assessment for substances commonly abused. Despite Screening being economically efficient for dismissing drug use in most samples, any positive indication requires confirmation for legal acceptability. Samples that test presumptively positive during Screening necessitate additional validation.
For samples testing presumptively positive in the Screening phase, more hair is extracted from the original specimen for the Extraction process. Drugs are isolated from the hair at significantly lower concentrations compared to other methods (ex. urine or oral fluid), which makes hair drug screening the most challenging technique to conduct.
Positive screening outcomes undergo Confirmation by means of GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation when necessary. The complete laboratory procedure from Accessioning to Confirmation is verified under both the CAP (College of American Pathologists) Hair directive and the ISO / IEC 17025 certification standards.
