Recognized as a formidable method for identifying substance consumption, hair testing offers a comprehensive timeline of drug and alcohol intake. Hair fibers capture biomarkers within the strands, offering a retrospective observation of up to three months when gathered close to the scalp. The procedure is straightforward, resistant to tampering, and effortless to transport.
A section measuring 1.5 inches of approximately 200 hair strands, akin to the diameter of a #2 pencil, offers the optimal 100mg sample necessary for screening and validation. For extended tests, including EtG, extra options, or panels exceeding 10, it is advisable to use 150mg of the sample. The use of a jeweler’s scale for measurement is advised. In situations lacking scalp hair, an equivalent volume of body hair might be collected. "Head hair" pertains solely to scalp hair, whereas "body hair" encompasses other varieties (e.g., facial, axillary).
Process Overview
The laboratory procedure for producing a drug test outcome consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the introduction of a specimen to the lab's system, ensuring it is sealed and shipped correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry omitted by the electronic chain of custody.
Screening performs an initial rapid evaluation for drug misuse. Although it serves as an economical strategy to exclude drug presence in most samples, confirmation is essential for legal acceptability of positive results. Samples showing presumptive positivity necessitate follow-up confirmation.
For samples with presumptive positivity during Screening, additional hair is taken for Extraction, wherein substances are extracted at considerably lower concentrations than using other methods (e.g., urine or oral fluid); hence, hair drug screening is notably challenging.
Confirmation of positive screening outcomes is done using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo cleaning before confirmation as necessary. The complete laboratory sequence from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 standard accreditation.
