Hair testing is increasingly recognized as an effective method for detecting drug and alcohol usage. Hair encapsulates a lengthy history of alcohol and drug intake by embedding biomarkers within the strands as they grow. Hair collected near the scalp can offer a detection range of up to 3 months for alcohol and other substances. Moreover, hair is easy to collect, relatively tamper-proof, and convenient for shipment.
A 1.5-inch segment consisting of roughly 200 hair strands (comparable in thickness to a #2 pencil) nearest the scalp yields 100mg, an optimal amount for both screening and confirmation procedures. For EtG, additional tests, or assessments exceeding 10 panels, a 150mg specimen is advisable. Using a jeweler's scale to weigh the sample is recommended. In cases where scalp hair is unavailable, an equivalent quantity of body hair can be used instead. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other types such as facial, axillary, etc.
Process Overview
The drug testing in laboratories encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a specimen into a laboratory's system. This step includes confirming the sample's proper sealing and shipment, assigning it a random LAN (Laboratory Accessioning Number), and inputting supplementary data not captured by an electronic chain of custody mechanism.
Screening performs an initial evaluation for substances of abuse. Although Screening is an economical method to rule out drug consumption across most samples, a positive result needs verification for legal acceptance. Presumptive positives in Screening necessitate further confirmation.
If a specimen appears presumptively positive during Screening, additional hair is extracted from the initial sample and processed for Extraction. This phase extracts drugs from hair, albeit at a lower concentration than other methods like urine or oral fluid testing, highlighting hair drug testing as the most challenging method to execute.
Confirmation for positive Screening outcomes utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing pre-confirmation. The entire lab process, from Accessioning to Confirmation, adheres to CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
