Hair Follicle Drug Testing - Woodstock, AL

What it is, How it works

Seen as a robust tool for detecting substance use, hair testing utilizes growing hair fibers to trap biomarkers, offering a historical record of alcohol and drug use. When sampled near the scalp, hair can reveal up to a three-month history for alcohol and drugs. It is straightforward to collect, challenging to tamper with, and easy to send.

Gathering a 1.5-inch segment of approximately 200 hair strands (akin to a #2 pencil) near the scalp yields 100mg, ideal for screening and verification. For EtG, additional tests, or those over ten panels, 150mg of hair is advisable, best measured using a jeweler’s scale. If scalp hair can't be collected, an equivalent volume of body hair can be used. "Head hair" specifically refers to scalp hair, while "body hair" pertains to all other types (facial, underarm, etc.).

Process Overview

In lab processing of drug test results, four major steps occur: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is introduced into the lab's system, which involves checking the sample's seal and shipment, assigning a Lab Accessioning Number (LAN) randomly, and completing any further data entry absent from an electronic custody chain.

Screening offers a swift preliminary check for substance abuse. Although cost-effective for eliminating drug use in most cases, a positive screen must be confirmed for legal admissibility. Samples testing presumptively positive necessitate further confirmation.

If the Screening phase yields a presumptive positive, additional hair is gathered from the original sample for Extraction, extracting drugs from hair at lower concentrations than other methods (like urine or saliva), making it the most challenging form of drug screening of hair.

Confirmation of positive screens is done using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed as needed before confirmation. The full lab process, from Accessioning to Confirmation, is reviewed under the CAP (College of American Pathologists) Hair badge and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can find drug use up to 90 days back, as opposed to urine tests with a shorter detection span.
• Hard to manipulate: It's exceedingly tough to cheat a hair drug test, resulting in more precise outcomes.
• Shows historical use: It reveals a drug use pattern over time, not just recent usage.

Limitations:

• Lacks recent use detection: Drugs become detectable in hair only after about 5-7 days.
• Expense: Hair drug tests tend to be pricier than alternative testing approaches.
• Result variability: Elements such as hair color and personal hair growth variations may influence drug metabolite levels in hair.

Note: Though commonly called "hair follicle tests", the test examines the hair strand, 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix.
