Hair testing has emerged as a significant means for identifying drug and alcohol consumption. Hair offers a long-duration record of substance use by embedding biomarkers within the developing hair strand fibers. Collected near the scalp, hair can reveal up to around a 90-day window of detection for alcohol and other substances. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A segment of 1.5 inches with roughly 200 hairs (approximately the thickness of a #2 pencil) close to the scalp yields 100mg of hair, an ideal quantity for examination and verification. For EtG, add-ons, and/or tests beyond 10 panels, a quantity of 150mg is advisable. We suggest weighing the sample using a jeweler's scale. If scalp hair cannot be obtained, a comparable quantity of body hair is an option. By head hair, we mean only scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The principal phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the first handling of a sample within a lab's system. This entails confirming the sample was correctly sealed and sent, assigning an arbitrary LAN (Laboratory Accessioning Number), and finishing any extra data input not furnished by a digital chain of custody system.
Screening involves an initial swift assessment for substance abuse. Screening is a cost-saving method to exclude drug usage for most samples, but any positive findings need verification for court acceptability. Samples with presumptive positives from Screening require secondary confirmation.
If Screening results lead to a presumptive positive, additional hair is extracted from the original specimen for Preparation. In this phase, drugs are separated from hair at significantly lower concentrations than other methods (i.e., urine or oral fluids), hence hair drug testing is the most arduous method.
Confirmation of any positive screen is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are cleansed prior to required confirmation. The complete lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair accreditation and the ISO / IEC 17025 standards.
