Hair analysis has emerged as a significant method for identifying drug and alcohol consumption. Hair offers a prolonged historical record of substance use by embedding biomarkers within the strands as they grow. When obtained near the scalp, hair can reveal drug and alcohol intake over a period of up to roughly three months. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.
A 1.5-inch section of around 200 hair strands (comparable in size to a #2 pencil) near the scalp provides a sample of 100mg, which is optimal for testing and verification. For EtG, additional tests, and/or panels exceeding 10, a sample size of 150mg is advisable. It's suggested to use a jeweler's scale for specimen measurement. If scalp hair is not accessible, an equivalent volume of body hair may be utilized. In terms of head hair, this specifically refers to scalp hair. Other hair types (facial, axillary, etc.) are categorized as body hair.
Process Overview
The drug testing laboratory process comprises four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary processing of a specimen within a lab's system. This step includes ensuring the sample's proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing any subsidiary data entry not captured by an electronic chain of custody process.
Screening acts as an initial examination for drugs of abuse. Although Screening is a cost-efficient approach to dismiss drug use for most samples, a positive screen demands confirmation to be legally valid. Samples with a presumptive positive result in Screening necessitate further confirmation.
Should a sample yield a presumptive positive during Screening, additional hair is extracted from the original specimen and prepared for Extraction. In this phase, drugs are retrieved from hair at a much lower concentration compared to other techniques (e.g., urine or oral fluid), underscoring the complexity of hair drug testing methodologies.
Confirmation of a positive screen is performed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples presumed positive are cleansed prior to confirmation if deemed necessary. The full laboratory procedure, from Accessioning to Confirmation, is evaluated based on the CAP (College of American Pathologists) Hair standards and the accreditation of ISO / IEC 17025 benchmarks.
