Hair testing is now recognized as an effective means for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug intake by capturing biomarkers within the fibers of the developing hair shaft. When extracted near the scalp, hair can offer roughly a 3-month detection period for alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and uncomplicated to transport.
A segment of 1.5 inches with around 200 hairs (approximately as thick as a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal quantity for evaluation and verification. For EtG, add-ons, or tests beyond 10 panels, 150mg is advised. It's suggested to measure the sample with a jeweler’s scale. If scalp hair isn't accessible, a similar volume of body hair may be utilized. When mentioning head hair, it specifically means scalp hair. Body hair covers all other types (facial, armpit, etc.).
Process Overview
The primary phases in the laboratory workflow of processing drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into the lab’s framework. This process checks if the sample was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and fills in any data ommissions absent from an electronic chain of custody system.
Screening performs a preliminary rapid assessment for substance abuse. Although Screening is a cost-efficient approach to exclude drug use in most samples, a positive result must be validated for legal proceedings. Any samples with presumptive positive results in Screening require secondary confirmation.
When a sample is presumptively positive during Screening, additional hair is taken from the original sample and prepped for Extraction. Here, drugs are extracted from hair at a much lower density compared to other methods (e.g., urine or oral fluid), contributing to hair drug screening being one of the most challenging methods to execute.
Confirmation of any presumptive positive screen result is done through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as needed. The full lab procedure from Accessioning to Confirmation is reviewed in alignment with the CAP (College of American Pathologists) Hair designation and accredited according to ISO / IEC 17025 standards.
