Hair Follicle Drug Testing - Gorman, NC

What it is, How it works

Hair testing is increasingly recognized as an effective means for discovering drug and alcohol consumption. Hair strands offer a prolonged timeline of substance use by capturing biomarkers within the fibers as they grow. Collected near the scalp, hair samples can indicate substance use within a roughly 3-month timeframe. Hair is straightforward to gather, relatively hard to tamper with, and easy to send.

A hair sample of 1.5 inches consisting of approximately 200 strands (similar in thickness to a #2 pencil) close to the scalp yields 100mg, which is optimal for screening and confirming results. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advised. Using a jeweler's scale to measure the sample is recommended. If scalp hair is not present, an equal quantity of body hair can be used. The term head hair pertains solely to scalp hair, whereas body hair includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test comprises four crucial steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is incorporated into a laboratory's system, verifying proper sealing and shipment, assigning an LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.

Screening serves as a preliminary check for drugs of abuse. Although Screening is economical for excluding drug usage in most samples, a positive screen must be verified to be court-admissible. Any samples that show potential positives in Screening must undergo a secondary confirmation.

For samples indicated as positive during Screening, more hair is extracted from the initial sample and readied for Extraction. Here, drugs are drawn from hair at much lower concentrations than other methods (such as urine or oral fluid), which accounts for the complexity of hair drug screening.

Confirmation of any positive Screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples undergo washing before confirmation if needed. The full laboratory process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug testing can reflect drug use for up to 90 days, far longer than urine tests.
• Challenging to evade: Attempting to cheat a hair drug test is extremely difficult, enhancing result accuracy.
• Offers historical insight: It illustrates a pattern of drug use over time, beyond just recent usage.

Limitations:

• Inability to detect recent use: It requires roughly 5-7 days for drugs to become detectable in hair strands.
• Cost: Compared to other methods, hair drug tests tend to be more expensive.
• Result variations: Factors such as hair color and individual growth rates can influence drug metabolite concentrations in hair.

Note: While they are often dubbed "hair follicle tests," the analysis targets 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. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
