Hair testing is increasingly recognized as a robust method for identifying drug and alcohol consumption. Hair can reveal a prolonged history of substance use by locking in biomarkers within the fibers of the hair as it grows. When collected near the scalp, hair samples can provide around a 3-month detection period for substances. Hair collection is straightforward, difficult to tamper with, and convenient for transport.
A 1.5-inch section of roughly 200 hairs (comparable to a #2 pencil) closest to the scalp will yield 100mg, the preferable quantity for analysis and confirmation. For EtG, add-ons, and more than 10 panels, a sample of 150mg is advised. We suggest measuring the hair using a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be used. When mentioning head hair, we mean scalp hair. Body hair encompasses all other types (such as facial and axillary hair).
Process Overview
The core steps in the lab analysis of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves putting a sample into the lab’s records system. This step includes ensuring the sample was correctly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody.
Screening entails an initial rapid assessment for substance misuse. While Screening is an affordable measure to eliminate drug use in the majority of cases, a positive screen must be validated for court use. Any samples that test positive in Screening require a follow-up confirmation.
Should a sample indicate a positive result during Screening, additional hair is extracted from the primary specimen and processed for Extraction. In this phase, substances are pulled from hair at markedly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing the most challenging method to perform.
Confirmation of a positive Screening result is undertaken using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples labeled as presumptive positive are cleansed before confirmation as necessary. The overall lab procedure from Accessioning to Confirmation is assessed both under the CAP (College of American Pathologists) Hair designation and the accreditation of ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although frequently termed as "hair follicle tests", the analysis targets the hair strand rather than the follicle beneath the scalp.
