Hair testing is now recognized as an effective method for identifying drug and alcohol usage. Hair traps biomarkers in its fibers, providing a comprehensive history of substance intake by retaining these markers as the hair grows. When sampled near the scalp, hair offers up to a 90-day window to detect substances. It's straightforward to collect, challenging to tamper with, and convenient to transport.
A 1.5-inch piece containing roughly 200 strands (similar in size to a #2 pencil) closest to the scalp provides the necessary 100mg for analysis. For EtG, add-ons, and/or tests exceeding 10 panels, a sample weighing 150mg is preferable. We advise using a jeweler’s scale to weigh the sample. In the absence of scalp hair, a comparable amount of body hair can be used. The term head hair is specific to scalp hair, while body hair encompasses other types (such as facial and axillary hair).
Process Overview
The laboratory procedure for processing a drug test result comprises four essential stages: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the sample is initially registered in the lab’s system. This step ensures the sample's seal and shipping integrity, assigns a random LAN (Laboratory Accessioning Number), and involves any supplementary data entry absent in an electronic chain of custody.
Screening performs a preliminary check for substance abuse. Although cost-efficient for ruling out drugs in most samples, a positive result requires confirmation to be valid for legal purposes. All samples that test presumptively positive during Screening necessitate further verification.
For samples that test presumptive positive at Screening, additional hair is extracted and prepared for the Extraction stage. In this phase, drugs are drawn from hair at concentrations significantly less than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
Confirmation of any positive from Screening utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before confirmation as necessary. The entire process from Accessioning to Confirmation undergoes thorough review according to CAP (College of American Pathologists) Hair designation and accreditation under ISO / IEC 17025 standards.
