Recognized as an effective instrument, hair analysis for drug and alcohol detection captures long-term usage patterns by embedding biomarkers within the hair’s fibers during growth. When obtained near the scalp, hair offers a detection period of approximately three months for alcohol and drug presence. The collection is straightforward, tampering is challenging, and the transportation is uncomplicated.
By gathering a 1.5-inch section comprising roughly 200 hair strands (similar to a #2 pencil diameter) nearest to the scalp, you acquire 100mg of hair, which is optimal for evaluation and validation. In cases involving EtG, additional requests, and tests exceeding 10 panels, securing 150mg of the sample is preferred, and utilizing a jeweler’s scale for measurement is advisable. If scalp hair is absent, a comparable volume of body hair may be used. "Head hair" pertains solely to scalp hair, while "body hair" encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
Key procedures in laboratory processing of a drug test consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into the laboratory’s system. This step ensures the sample was appropriately sealed and transported, allocates a random LAN (Laboratory Accessioning Number), and fills in any lacking data not supplied by an electronic chain of custody system.
Screening performs an initial, swift evaluation for drug presence. While it is a cost-efficient method to exclude drug usage in many samples, a confirmed positive is essential for court acceptability, necessitating secondary confirmation for any presumptively positive samples in Screening.
For samples deemed presumptively positive during Screening, additional hair is extracted from the initial specimen for Extraction. This step retrieves drugs from hair at significantly lower concentrations than other methodologies (e.g., urine or oral fluid), highlighting why hair drug testing is the most intricate methodology.
Confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Each presumptive positive sample undergoes washing before confirmation. The comprehensive laboratory workflow from Accessioning to Confirmation is inspected under the CAP (College of American Pathologists) Hair classification and accords with ISO / IEC 17025 standards.
