Recognized as a potent mechanism, hair testing detects drug and alcohol consumption effectively. Hair encapsulates a prolonged history of alcohol and drug use by embedding biomarkers within the strands' fibers. Collected near the scalp, hair can uncover alcohol and drug usage spanning up to a three-month timeframe. It's straightforward to gather hair, hard to tamper with, and convenient for transportation.
Giving around 100mg, a 1.5-inch sample of roughly 200 strands (similar to the thickness of a #2 pencil) from the scalp stands as the ideal specimen for both screening and confirmation. For add-ons like EtG or tests exceeding 10 panels, 150mg is advisable. It's suggested to gauge the specimen’s weight using a jeweler's scale. If scalp hair isn't obtainable, a corresponding quantity of body hair is another option. References to head hair are specific to scalp hair. Body hair encompasses all other hair classifications (facial, armpit, etc.).
Process Overview
The process of assessing a drug test result in a lab includes four core steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the introductory handling of a sample into a lab's framework. This step ascertains the sample's proper sealing and dispatch, assigns a random LAN (Laboratory Accessioning Number), and completes any leftover data entry absent in an electronic chain of custody system.
Screening acts as an initial rapid assessment for drug abuse. While Screening efficiently eliminates drug use in most samples cost-effectively, confirming a positive screen is necessary for court acceptability. Samples showing presumptive positivity require a subsequent confirmation step.
In cases of presumptive positivity during Screening, additional hair is extracted from the initial sample and readied for Extraction. This phase involves extracting drugs from hair at concentrations significantly lower than methods like urine or oral fluid, making hair drug testing quite challenging.
Confirmation of any Screening positivity involves using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo washing as appropriate. The overall lab process from Accessioning through Confirmation undergoes review in alignment with both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed "hair follicle tests", the assessment examines the hair strand itself and not the hair follicle situated beneath the scalp.
