Hair testing has evolved into an effective means for identifying drug and alcohol consumption. Hair serves as a long-term archive for alcohol and drug usage by embedding biomarkers within the strands of hair that are growing. When gathered near the scalp, hair can yield approximately up to a 3-month period for detecting alcohol and drugs. Hair is straightforward to obtain, relatively resistant to tampering, and simple to transport.
A 1.5-inch segment of nearly 200 hair strands (about as wide as a #2 pencil) nearest the scalp will provide 100mg of hair, the optimal quantity for both screening and validation. For EtG, supplementary tests, and/or tests above 10 panels, 150mg of the sample is suggested. We advise using a jeweler’s scale to weigh the sample. If scalp hair is not available, a comparable quantity of body hair can be collected. References to head hair pertain exclusively to scalp hair, while body hair encompasses other hair types (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result encompasses four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a laboratory’s system. This step includes confirming the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data input not furnished by an electronic chain of custody system.
Screening conducts an initial rapid assessment for drug abuse. Although Screening is an economical approach to exclude drug usage in the majority of samples, a screen showing positive results must be validated to be permissible in legal settings. Samples that test presumptive positive in Screening necessitate secondary confirmation.
If a sample shows presumptive positive results during the Screening phase, additional hair is extracted from the original specimen and readied for Extraction. At this stage, drugs are removed from hair at considerably lower concentrations than other methods (ex. urine or oral fluid), which contributes to hair drug screening being the most challenging method to execute.
Verification of any positive screening outcome is done through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing prior to verification as required. The full laboratory mechanism from Accessioning to Confirmation undergoes examination under both the CAP (College of American Pathologists) Hair designation and the compliance with ISO / IEC 17025 standards.
