Hair analysis is recognized as a robust method for spotting substance and alcohol consumption. Hair captures a prolonged record of alcohol and various drugs by encasing biomarkers within the structure of the maturing hair strand. When collected near the scalp, hair offers up to a roughly 90-day detection span for alcohol and other substances. Collecting hair is straightforward, relatively hard to tamper with, and uncomplicated to dispatch.
A 1.5-inch segment consisting of about 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is ideal for screening and validation. For EtG, additional tests, and/or anything exceeding 10 panels, it's recommended to have 150mg of the sample. We suggest using a jeweler’s scale to weigh the specimen. In the absence of scalp hair, an equivalent quantity of body hair can be gathered. Referring to head hair denotes only scalp hair. Body hair pertains to all other hair types (facial, axillary, etc.).
Process Overview
The four pivotal steps in a lab's processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial handling of a sample within a lab’s system. This step comprises checking that the sample was adequately sealed and transported, allocating a random LAN (Laboratory Accessioning Number), and finishing any further data input not provided by an electronic chain of custody system.
Screening involves a preliminary rapid examination for drug abuse. Though Screening is a cost-efficient method to eliminate drug usage for the bulk of samples, a positive outcome must be validated to be permissible in court. Any samples that show a presumptive positive in Screening require additional confirmation.
Should a sample test positive during Screening, more hair is extracted from the original specimen and prepped for Extraction. During this phase, drugs are separated from hair at concentrations significantly lower than other methods (ex. urine or oral fluid), which makes hair drug screening notably challenging to execute.
Whether a positive screening result arises, it is confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are washed before confirmation when necessary. The full lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair standard and accreditation to ISO / IEC 17025 benchmarks.
