Hair testing has become widely acknowledged as an effective method for detecting the use of alcohol and drugs. Hair serves as a reliable historical record by capturing biomarkers within the fibers of the hair shaft as it grows. When obtained near the scalp, hair can offer approximately a 90-day window for detecting drugs and alcohol. Hair is straightforward to collect, not easily altered, and simple to transport.
A sample measuring 1.5 inches consisting of roughly 200 hair strands (around the thickness of a #2 pencil) nearest to the scalp yields 100mg, which is the optimal quantity for both screening and confirmation. For EtG, add-ons, or testing beyond 10 panels, a 150mg sample is advisable. Use a jeweler's scale to measure the sample. If scalp hair is unavailable, a comparable amount of body hair may be utilized. When we mention head hair, we mean scalp hair specifically. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four principal stages in processing a drug test result in the laboratory comprise Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab's system. It includes verifying the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody system.
Screening performs an initial rapid check for drug abuse. While Screening is an economical method to dismiss drug usage in most samples, any positive result must be confirmed for court validity. Samples showing presumptive positive results during Screening require secondary confirmation.
When a sample shows a presumptively positive result in the Screening phase, additional hair is taken from the initial sample for Extraction. In this stage, drugs are removed from hair at much lower concentrations compared to methods like urine or oral fluid, making hair drug testing the most challenging methodology to execute.
Confirmation of all positive screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation as necessary. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
