Seen as a formidable mechanism, hair testing effectively identifies drug and alcohol consumption. By capturing biomarkers within the fibers of a developing hair strand, hair offers a retrospective account of alcohol and other drug usage. When procured near the scalp, hair can present a detection timeframe of up to roughly three months for alcohol and various drugs. Hair is straightforward to gather, fairly resistant to tampering, and simple to transport.
An ideal screening and confirmation specimen consists of a 1.5-inch segment of roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp, yielding 100mg of hair. For tests such as EtG, add-ons, and/or those over 10 panels, a specimen amounting to 150mg is advisable. We suggest using a jeweler's scale to weigh the sample. In the absence of scalp hair, an equivalent quantity of body hair may be collected. References to head hair exclusively pertain to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The lab processing of drug test outcomes encompasses four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning describes the initial incorporation of a sample into the lab’s framework. This process involves confirming proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and recording supplementary information absent in an electronic chain of custody setup.
Screening constitutes an initial rapid assessment for abusive substances. While this economical approach efficiently excludes drug use in most cases, a positive indication necessitates confirmation for legal acceptance. Samples preliminarily testing positive in Screening must undergo further confirmation.
Upon a presumptive positive result in the Screening phase, additional hair is extracted from the initial sample and prepped for Extraction. In this phase, drugs are derived from hair at significantly lower concentrations compared to alternative techniques (e.g., urine or oral fluid), making hair drug testing the most challenging technique to perform.
GC/MS, GC/MS/MS, or LC/MS/MS methods are used to confirm positive screening findings. Before confirmation, all samples preliminarily positive are washed as required. From Accessioning through Confirmation, the complete laboratory procedure adheres to both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
