Hair testing has emerged as a significant method for identifying drug and alcohol consumption. Hair offers a prolonged timeline of substance use by embedding biomarkers within the hair's fibers as it grows. When the sample is taken near the scalp, hair can reveal up to a roughly 3-month period for detecting drugs and alcohol. Hair collection is straightforward, tampering with it is somewhat challenging, and it is uncomplicated to transport.
A sample measuring 1.5 inches containing approximately 200 hair strands (similar in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal amount for both screening and confirming results. For EtG, additional tests, and/or tests exceeding 10 panels, a specimen size of 150mg is advised. Using a jeweler’s scale to weigh the specimen is suggested. In the absence of scalp hair, a similar quantity of body hair may be gathered. When discussing head hair, we specifically mean scalp hair. Body hair pertains to all other types of hair (facial, axillary, etc.).
Process Overview
The drug testing process in a laboratory encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into the laboratory's system. This step involves ensuring the sample has been appropriately sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody system.
Screening constitutes a preliminary rapid evaluation for substances of abuse. Despite being an economical approach to dismiss drug usage in most samples, a positive screening result necessitates confirmation to be valid in legal settings. Samples that exhibit a presumptive positive in Screening necessitate a further validation process.
If Screening indicates a presumptive positive, additional hair is extracted from the primary specimen for the Extraction phase. During Extraction, drugs are isolated from the hair at a significantly lower concentration compared to other testing methods (like urine or oral fluid), underscoring the complexity of conducting hair drug screening.
Positive screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing prior to confirmation as needed. The entire laboratory sequence from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
