Hair testing is regarded as an effective means to identify drug and alcohol consumption. Hair offers a long-term record of alcohol and other substances by capturing biomarkers within the strands of hair as they grow. By collecting hair near the scalp, it’s possible to obtain a detection timeline of up to roughly 3 months for various substances. Hair is straightforward to collect, notably challenging to tamper with, and convenient to transport.
A 1.5-inch segment comprising around 200 hair strands (about the width of a #2 pencil) nearest the scalp yields 100mg of hair, which is the optimal sample for analysis and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of hair is advisable. We suggest measuring the sample on a jeweler’s scale. If scalp hair is unavailable, a comparable quantity of body hair can be gathered. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result entails four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a specimen into a lab's workflow. This step includes ensuring the sample was properly sealed and dispatched, issuing a random LAN (Laboratory Accessioning Number), and completing any remaining data input not covered by an electronic chain of custody system.
Screening provides an initial and rapid assessment for drug abuse. While it serves as an economical method to dismiss drug usage in the bulk of samples, a positive screening outcome must be ratified for legal acceptability. Samples that are presumptively positive during Screening demand additional confirmation.
If a sample shows a presumptive positive during Screening, additional hair is collected for Extraction. This phase involves separating drugs from hair with reduced concentrations compared to other techniques (ex. urine or saliva), which makes hair drug testing one of the most intricate methods to execute.
Confirmation of any positive screening outcomes is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing prior to confirmation as required. The complete lab process, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
