Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair retains a long-term record of such substances by encapsulating biomarkers within the fibers of the hair strand as it grows. When obtained near the scalp, hair can reveal a detection period for drugs and alcohol up to roughly three months. The process of collecting hair is straightforward, somewhat resistant to tampering, and convenient for transport.
A segment measuring 1.5 inches and comprising roughly 200 strands (comparable in size to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample size for both screening and confirmation tests. For EtG, add-ons, or panels exceeding 10, it is advisable to collect 150mg of the sample. Accurate measurement of the sample using a jeweler's scale is recommended. If scalp hair cannot be retrieved, an equivalent quantity of body hair is an option. By head hair, we mean exclusively scalp hair. Body hair encompasses all other types (like facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is entered into a laboratory’s system, ensuring it has been securely sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data that hasn't been provided by an electronic chain of custody.
Screening conducts an initial fast assessment for drugs of abuse. Though cost-effective, a positive screen in Screening must be validated to be legally acceptable. Any samples that are preliminarily positive in Screening need further confirmation.
Upon a presumptively positive outcome in the Screening stage, additional hair is drawn from the initial sample and arranged for Extraction. Here, drugs are removed from hair at significantly lower concentrations compared to other systems (like urine or saliva), rendering hair drug screening the most challenging to execute.
Confirmation of any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as per necessity. The entire laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair guidelines and compliance with ISO / IEC 17025 standards.
