Hair analysis is viewed as an effective means for identifying drug and alcohol use. Hair captures a prolonged record of drug and alcohol consumption by enclosing biomarkers within the strands as they grow. When gathered near the scalp, hair offers approximately a three-month period for detecting alcohol and drugs. Hair is easy to collect, less prone to adulteration, and simple to send.
A sample measuring 1.5 inches with around 200 hairs (comparable to a #2 pencil) from the scalp provides 100mg of hair, the optimal quantity for both screening and confirmation. For EtG, additional testing, and/or panels exceeding 10, a 150mg specimen is advised. It's best to measure the specimen using a jeweler’s scale. Should scalp hair not be available, a similar quantity of body hair may be used. References to head hair pertain strictly to scalp hair. Body hair includes all other variants (such as facial, axillary hair).
Process Overview
The drug test lab process consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a lab sample. This steps involve confirming appropriate sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry not fulfilled by an electronic chain of custody system.
Screening acts as a rapid initial evaluation for substances of abuse. Screening is an efficient way to exclude drug use in most samples, but a positive screen must be validated for court acceptance. Any samples with a presumptive positive result in Screening need additional confirmation.
When a sample has a presumptive positive outcome during Screening, more hair is extracted from the sample and prepped for Extraction. This stage involves extracting drugs from hair at much lower concentrations compared to other methods (like urine or oral fluid), rendering hair drug testing as the most challenging method to conduct.
Confirmation for any positive screening outcome is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as necessary. The complete lab process from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
