Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers, offering a prolonged record of alcohol and substance use. When collected near the scalp, it can indicate substance usage for up to about three months. Hair is easy to gather, challenging to tamper with, and straightforward to transport.
A 1.5-inch section comprised of roughly 200 hair strands (approximately the size of a #2 pencil) adjacent to the scalp yields 100mg of hair, which is the optimal amount for testing and validation. For EtG, additional measures, and/or tests beyond 10 panels, 150mg of the sample is advised. We advocate using a jeweler's scale for weight accuracy. Should scalp hair be unavailable, an equivalent amount of body hair can be gathered. For clarity, head hair refers to scalp hair exclusively. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The key steps in the lab analysis of a drug screening result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into the laboratory's system. This process ensures that the sample was properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and finalizes any essential data input not captured by an electronic chain of custody system.
Screening consists of a preliminary evaluation for drugs of misuse. While Screening is an economical method to exclude drug use for most samples, a positive reading must be verified for legal admissibility. Samples showing presumptive positive results during Screening require further confirmation.
If a sample tests presumptively positive during Screening, additional hair is taken from the original sample and readied for Extraction. In this phase, drugs are extracted from hair at notably lower concentrations compared to other techniques (such as urine or oral fluid), establishing hair drug screening as the most intricate procedure to execute.
Confirmation of any positive screening outcome is executed utilizing GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptively positive undergo washing before confirmation as necessary. The comprehensive lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.
