Hair testing has become recognized as a potent means for identifying the usage of drugs and alcohol. Hair entraps biomarkers within the fibers of the growing strand, offering a historical overview of alcohol and other drugs. When gathered near the scalp, hair can offer a detection window of up to approximately 3 months for alcohol and other drugs. Hair collection is uncomplicated, relatively tamper-resistant, and straightforward to ship.
A 1.5-inch piece consisting of about 200 hair strands (comparable in size to a #2 pencil) nearest the scalp will provide 100mg of hair, which is the optimal sample size for screening and confirmation. For EtG, additional tests, and/or those beyond 10 panels, a specimen of 150mg is advised. It's suggested to measure the specimen using a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair may be used. By head hair, we mean scalp hair specifically. Body hair refers to all other types including facial, axillary, etc.
Process Overview
The main steps in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab’s system. This step includes ensuring the sample was sealed and shipped correctly, generating a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry missing from an electronic chain of custody system.
Screening serves as a preliminary assessment for drugs of abuse. Although it's a cost-effective method to rule out drug usage in most samples, a positive screen must be confirmed to be court admissible. Presumptively positive samples in Screening need secondary confirmation.
If a sample shows presumptive positivity during Screening, additional hair is extracted from the initial sample and readied for Extraction. Here, drugs are retrieved from hair at much lower concentrations than other methodologies (e.g. urine or oral fluid), which is why hair drug testing is the most challenging methodology to execute.
Positive screening results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positivity are washed as necessary before confirmation. Every step from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair designation and accreditation standards of ISO / IEC 17025.
