Hair analysis is recognized as an effective method for identifying alcohol and drug use. The hair captures biomarkers in the strands as they grow, offering a prolonged record of substance usage. Obtaining samples near the scalp can reveal approximately a three-month insight into alcohol and drug usage. Collection is straightforward, adjusting the sample is challenging, and transportation is convenient.
A sample measuring 1.5 inches with about 200 hairs (similar to the thickness of a #2 pencil) near the scalp yields 100mg, optimal for both screening and confirmation. For EtG, supplementary tests, and tests beyond 10 panels, a 150mg specimen is advisable. It's suggested to use a jeweler’s scale to measure the sample. If scalp hair is unavailable, a matching amount of body hair can be collected. "Head hair" indicates scalp hair only. "Body hair" encompasses all other hair types (e.g., facial, axillary).
Process Overview
The key phases in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with integrating a sample into the laboratory's system, ensuring correct sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entry if not available electronically.
Screening conducts a preliminary check for drug abuse. Although Screening efficiently rules out drug usage for most samples, any positive results require confirmation to be valid in legal settings. Positive samples from Screening need a secondary validation.
Presumptive positives in the Screening lead to more hair samples from the initial collection for Extraction. During Extraction, the drug concentration extracted from hair is much lower than other methods (e.g., urine, oral fluid), emphasizing the complexity of hair drug testing.
Confirmation of positive Screening outcomes uses GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples undergo washing as needed before confirmation. The whole lab process from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
