Hair examinations are now recognized as an effective method for detecting substance and alcohol consumption. Hair captures a long-term record of drugs and alcohol by locking biomarkers within the fibers of the developing hair strand. When taken near the scalp, hair offers nearly a 3-month span for detecting substances and alcohol. It's easy to gather, relatively resistant to tampering, and simple to mail.
A 1.5-inch portion of about 200 hair strands (about as thick as a #2 pencil) closest to the scalp yields 100mg of hair, which is optimal for analysis and verification. For EtG, additional tests, and/or tests with more than 10 panels, 150mg of the sample is advised. We suggest measuring the sample with a jeweler’s scale. In cases where scalp hair isn't available, an equivalent amount of body hair may be used. When referencing head hair, it pertains solely to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The process for lab analysis of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial incorporation of a sample into a lab's system. This involves confirming the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.
Screening represents an initial rapid check for drug abuse. While Screening is a cost-efficient method to eliminate drug usage in most samples, a positive result requires confirmation to be court-admissible. Any samples presumptively positive in Screening necessitate a secondary confirmation.
For samples presumed positive in Screening, additional hair is taken from the initial sample and readied for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations than other techniques (ex. urine or oral fluid), which explains why hair drug testing is a challenging methodology.
Confirmation of a positive screening outcome is executed via GC/MS, GC/MS/MS or LC/MS/MS. All preliminary positive samples undergo washing before confirmation as required. The comprehensive laboratory sequence from Accessioning to Confirmation aligns with both the CAP (College of American Pathologists) Hair standard and ISO / IEC 17025 accreditation.
