Hair testing is perceived as a formidable method for identifying drug and alcohol consumption. Hair captures a prolonged history by securing biomarkers within the fibers of the extending hair strand. When gathered near the scalp, hair offers an estimated 3-month detection timeframe for alcohol and drugs. Hair collection is straightforward, moderately resistant to tampering, and convenient to transport.
An ideal 1.5-inch portion of about 200 hair strands (ordinarily the size of a #2 pencil) nearest to the scalp produces 100mg of hair, the preferred sample for both screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, 150mg of the sample is advisable. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair isn’t available, an equivalent amount of body hair may be gathered. When discussing head hair, we specifically mean scalp hair; body hair denotes any other types (facial, axillary, etc.).
Process Overview
The laboratory procedures for processing a drug test result encompass Accessions, Screening, Extraction, and Confirmation.
Accessions entails the primary handling of a sample into the lab’s system. It includes verifying the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any extra data entry absent in an electronic chain of custody system.
Screening provides a quick initial assessment for substances of abuse. While Screening is a budget-friendly method to rule out drug usage for most samples, a positive screen must be confirmed to hold up in legal settings. Samples that are presumptively positive in Screening demand secondary confirmation.
Upon a presumptive positive in Screening, additional hair is extracted from the original sample for Extraction. Here, drugs are isolated from hair at significantly lower concentrations versus other methods (e.g., urine or oral fluid), presenting the challenge of hair drug screening as the most complex methodology to conduct.
Any positive screening result is confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The complete lab process from Accessions to Confirmation is audited under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
