Hair testing is recognized as an effective instrument to identify drug and alcohol consumption. Hair retains biomarkers within its fibers over a prolonged timeframe, offering a retrospective view of substance use. Hair collected near the scalp can supply an approximately 3-month window of detection for these substances. The collection procedure is straightforward, the substance is relatively adulteration-resistant, and it ships with ease.
A 1.5-inch segment comprising roughly 200 hair strands (resembling the diameter of a #2 pencil) closest to the scalp is necessary to attain the optimal 100mg needed for examination and verification. For EtG, additional testing, or assessments beyond 10 panels, it's advised to acquire 150mg of the sample. We propose measuring the collected hair with a jeweler’s scale. Should scalp hair be unavailable, a comparable quantity of body hair may be substituted. When mentioning head hair, this pertains specifically to scalp hair. Body hair encompasses all other forms (facial, axillary, etc.).
Process Overview
The procedure of processing a drug test result in a laboratory is composed of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning incorporates introducing the sample into the laboratory’s system initially. This area encompasses verifying the sample’s intact, proper shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary entries absent from an electronic chain of custody protocol.
Screening is a preliminary rapid test for substance abuse. While an economical means to exclude drug usage in most samples, a positive screen requires validation for court acceptance. Samples that test positive during Screening need a subsequent confirmation.
If a sample returns a presumptive positive during Screening, more hair is separated from the original sample and prepped for Extraction. During Extraction, drugs are drawn out of hair at concentrations significantly lower than alternative methods (e.g., urine or oral fluid), making hair drug screenings notably challenging.
Verification of any positive screen is performed using GC/MS, GC/MS/MS or LC/MS/MS techniques. All samples with presumptive positives undergo washing before confirmation as necessary. Every phase from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair provisions and complies with ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
