Hair testing is recognized as a robust technique in identifying drug and alcohol consumption. It shows a comprehensive timeline of alcohol and drug use by capturing biomarkers in the structure of the growing hair. When sourced near the scalp, hair displays up to an approximate 3-month window for drug and alcohol detection. Hair is easy to gather, comparatively hard to tamper with, and straightforward to dispatch.
An optimal sample for examination and confirmation consists of a 1.5-inch segment from about 200 hair strands (roughly the thickness of a #2 pencil) closest to the scalp, yielding 100mg of hair. For tests involving EtG, add-ons, or above 10-panel tests, it is suggested to gather 150mg of the sample. Utilizing a jeweler’s scale for weighing the specimen is advisable. If scalp hair is not present, an equivalent quantity of body hair can be taken. In context, head hair specifically means scalp hair, while body hair encompasses all other forms (such as facial or axillary hair).
Process Overview
The laboratory evaluation of a drug test sample encompasses four critical steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the commencement of sample processing within a lab's framework. This step ensures the sample's proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and fills in any additional data not covered by an electronic chain of custody.
Screening executes a preliminary examination for substances of abuse. Although Screening is an economical means to potentially exclude drug use in many samples, a positive result must be verified for legal acceptability in court. Samples with a presumptively positive screen necessitate further confirmation.
For samples deemed presumptively positive during Screening, further hair is extracted from the original specimen and prepped for Extraction. This phase involves extracting drugs from hair at much lower concentrations than other methods (like urine or oral fluid), making hair drug testing a notably complex procedure.
Confirmation of any positive findings from Screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS methods. Before confirmation, presumptive positive samples undergo washing if necessary. The full suite of laboratory steps from Accessioning to Confirmation is structurally audited per both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
