The use of hair screening has emerged as an influential means for identifying substances including drugs and alcohol. Hair captures long-term substance consumption history by embedding biomarkers within its strands as it grows. When harvested near the scalp, hair testing spans up to around a 90-day detection period for alcohol and other substances. Its collection is straightforward, manipulation less feasible, and shipping effortless.
A section measuring 1.5 inches, comprising roughly 200 hair strands (comparable in diameter to a #2 pencil) nearest the scalp yields 100mg of hair, the ideal specimen amount for evaluation and validation. For EtG, additional testing, and/or panels exceeding ten, a specimen weight of 150mg is advisable. Using a jeweler’s scale is suggested for weighing the sample. In cases where scalp hair isn't obtainable, the gathering of an equivalent volume of body hair is permissible. 'Head hair' refers specifically to scalp hair, whereas 'body hair' denotes all other varieties (facial, axillary, etc.).
Process Overview
The four principal phases of lab processing for drug testing results incorporate Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary processing of a sample within a lab’s system. It involves verifying the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any data input that is not furnished by an electronic chain of custody system.
Screening entails an initial swift review for substance abuse. While Screening is a cost-efficient method to rule out drug consumption in most samples, any positive findings must undergo confirmation to be court-viable. Samples registering presumptive positive in Screening necessitate secondary validation.
In scenarios where the Screening phase indicates a presumptive positive result, additional hair is extracted from the primary sample and made ready for Extraction. During this phase, substances are drawn from hair at a significantly reduced concentration compared to other methodologies (such as urine or oral fluid), rendering hair drug testing one of the most complex methodologies to execute.
Validation of any presumptively positive screening is executed utilizing GC/MS, GC/MS/MS, or LC/MS/MS. All samples recorded as presumptive positive undergo washing before confirmation, as required. The entire lab procedure from Accessioning to Verification is overseen under CAP (College of American Pathologists) Hair guidelines and adheres to ISO / IEC 17025 accreditation standards.
