Hair testing has evolved into a crucial method for detecting drug and alcohol consumption. It captures a long-term usage history by encapsulating biomarkers within the strands of growing hair. By collecting hair near the scalp, it can reveal a drug or alcohol pattern up to a 3-month period. The collection of hair is straightforward, hard to tamper with, and convenient for transportation.
A sample measuring 1.5 inches from approximately 200 hair strands (comparable to a #2 pencil size) near the scalp will yield about 100mg of hair, which is optimal for preliminary testing and verification. For EtG, added tests, and/or analyses surpassing 10 panels, 150mg of the sample is advised. Measuring the sample on a jeweler's scale is recommended. If scalp hair isn’t accessible, an equivalent amount of body hair can be collected. When we reference head hair, it pertains only to scalp hair, while body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing drug test outcomes encompasses four critical steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial integration of a sample into a lab’s system. This process involves ensuring the proper sealing and shipment of the sample, creating a random LAN (Laboratory Accessioning Number), and fulfilling any supplemental data requirements outside an electronic chain of custody system.
Screening provides a preliminary rapid assessment for drugs of abuse. While it’s a cost-efficient approach for negating drug presence in most samples, to be valid in legal contexts, a positive screen must be verified. Any samples indicating potential positivity in Screening must undergo secondary confirmation.
For samples presumed positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. This step involves isolating drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), which establishes hair drug testing as the most complex method to perform.
Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All initially positive samples undergo washing prior to confirmation when necessary. The overarching lab process from Accessioning to Confirmation is evaluated under the guidelines of the CAP (College of American Pathologists) Hair designation and adheres to the ISO / IEC 17025 standards.
