Seen as a robust method for identifying drug and alcohol consumption, hair testing captures long-standing biomarker information within the fibers of growing hair. Collected near the scalp, hair reveals a drug and alcohol detection window reaching up to roughly 3 months. Hair collection is straightforward, challenging to alter, and convenient for shipping.
Gathering a 1.5-inch section of around 200 hair strands (comparable to a #2 pencil) closest to the scalp yields 100mg of hair, an ideal quantity for analysis. For EtG, additional tests, or panels beyond 10, a 150mg sample is suggested. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair isn't obtainable, a comparable quantity of body hair may be used. Head hair refers exclusively to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four key stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a lab system, ensuring proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data input absent from an electronic custody chain.
Screening entails a preliminary check for substance abuse. Though cost-efficient for excluding drug use in most samples, a positive screen requires further confirmation to be valid in legal settings. Samples showing presumptive positivity in Screening require additional confirmation.
If a sample shows presumptive positivity during Screening, additional hair is taken from the initial sample and readied for Extraction. Here, drugs are extracted from hair at notably lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening particularly challenging.
Positive screens undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are washed before confirmation as necessary. The process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
