Hair examinations are now acknowledged as an effective method for identifying drug and alcohol consumption. Hair captures long-term evidence of alcohol and drug intake by trapping biomarkers within the fibers of the growing strand. Sampling hair near the scalp can offer a detection period of up to around three months for both alcohol and other substances. Hair collection is straightforward, relatively hard to tamper with, and simple to dispatch.
A sample length of 1.5 inches, made up of roughly 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp results in 100mg of hair, which is the ideal amount for testing and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is advisable. It's recommended to weigh the hair sample using a jeweler’s scale. If the scalp hair is not available, an equivalent amount of body hair can be utilized. When mentioning head hair, it is strictly regarding scalp hair. Body hair encompasses all other forms (such as facial, axillary, etc.).
Process Overview
The main four stages in the laboratory assessment of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a sample into a lab’s workflow. This encompasses confirming that the sample is sealed and sent correctly, designating a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry not given by an electronic chain of custody system.
Screening consists of a preliminary rapid assessment for substances of abuse. Though Screening serves as an economical means to exclude drug use in most cases, a positive screening must be validated to be accepted legally. Any samples with a presumptive positive during Screening demand a subsequent confirmation.
If a specimen shows presumptively positive in the Screening phase, more hair is drawn from the initial sample and arranged for Extraction. Here, the extraction process retrieves drugs from hair at significantly lower concentrations compared to other techniques (such as urine or oral fluid), explaining why hair drug screening presents the most challenging methodology.
Validation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing before confirmation as necessary. The entire laboratory workflow from Accessioning to Confirmation adheres to review under both the CAP (College of American Pathologists) Hair specification and the ISO / IEC 17025 standards accreditation.
