Hair Follicle Drug Testing - Wells, VT

What it is, How it works

The utilization of hair testing has emerged as an effective approach for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and other substances by embedding biomarkers within the fibers of the developing hair strand. When extracted from near the scalp, hair may offer a detection timeframe of up to roughly three months for alcohol and other substances. The process of obtaining hair is straightforward, challenging to tamper with, and simple to transport.

A sample of 1.5 inches, consisting of about 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp, yields 100mg, which is the optimal amount for analysis and confirmation. For EtG, additional testing, and/or screenings exceeding 10 panels, a specimen of 150mg is advised. It is advisable to weigh the sample using a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair might be gathered. When mentioned as head hair, we specifically refer to scalp hair. Body hair encompasses all other types, such as facial, axillary, etc.

Process Summary

The four principal phases in the lab analysis of a drug test sample include Accessioning, Screening, Extraction, and Confirmation.

The Accessioning stage involves the initial integration of a sample into a lab’s system. This step confirms that the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry absent from an electronic chain of custody system.

Screening comprises an initial rapid inspection for substance abuse. While Screening efficiently excludes drug usage in most samples, a positive outcome requires validation to be acceptable in legal proceedings. Any samples that indicate a presumptive positive result in Screening necessitate a secondary confirmation.

Should a specimen be presumptively positive during the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. At this stage, substances are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), thus making hair drug screening the most complex methodology to conduct.

Verification of any positive screen result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo a wash before confirmation as needed. The full laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Hair drug testing benefits:

• Extended detection duration: Hair drug assessments can identify drug use for a period reaching 90 days, whereas urine tests have a briefer detection duration.
• Test integrity: It is exceptionally challenging to deceive a hair drug assessment, ensuring more precise outcomes.
• History of usage: It can reveal a pattern of drug use over a timeline, not solely recent consumption.

Drawbacks:

• Inability to identify recent usage: It requires about 5-7 days for substances to be traceable in hair.
• Expense: Hair drug assessments typically cost more than alternative drug testing techniques.
• Result discrepancies: Elements like hair color and variations in personal hair growth may influence drug metabolite levels in hair.

Note: Even though commonly described as "hair follicle tests", the analysis actually examines the hair strand and not the follicle beneath the scalp.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
