Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. By entrapping biomarkers within the fiber structure of the hair growing strand, hair offers an extended history of alcohol and other substances. When hair is gathered near the scalp, it can offer an approximate 3-month detection range for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and uncomplicated to transport.
A sample of 1.5 inches consisting of about 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample size for both screening and validation. For EtG, additional testing, and/or panels exceeding 10, a 150mg sample is advocated. It's advisable to measure the sample on a jeweler’s scale. If head hair is inaccessible, an equal quantity of body hair can be collected. In discussions about head hair, it specifically pertains to scalp hair only. Body hair references any other hair types (facial, axillary, etc.).
Process Overview
The procedure in the laboratory for generating a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the laboratory's system. This step ensures the sample was sealed and dispatched correctly, assigns a random Laboratory Accessioning Number (LAN), and completes any missing data entry not provided by an electronic chain of custody mechanism.
Screening is the initial fast check for substances of abuse. Even though Screening offers a cost-efficient method to eliminate drug use in most samples, a positive result needs affirmation to be court-admissible. Samples that indicate a presumptive positive during Screening require secondary verification.
If a sample presents a presumptive positive in the Screening phase, additional hair is extracted from the original sample and prepped for Extraction. In this phase, drugs are drawn from the hair at significantly lower concentrations than in alternative methodologies (such as urine or saliva), explaining why hair drug analysis is among the most challenging techniques to carry out.
Confirmation of any positive outcome in Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positives are cleansed before confirmation as necessary. The full lab process from Accessioning through Confirmation is monitored under both the CAP (College of American Pathologists) Hair criteria and the ISO/IEC 17025 accreditation.
