Hair Follicle Drug Testing - Little Rock, AR

What it is, How it works

Hair testing is recognized as an effective method for detecting drug and alcohol consumption. Hair offers a comprehensive historical record of alcohol and drug usage by embedding biomarkers within the fibers of the hair shaft as it grows. When the hair is collected near the scalp, it can offer up to a 3-month detection period for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and easy to transport.

Obtaining a 1.5-inch segment consisting of around 200 hair strands (approximately the thickness of a #2 pencil) nearest the scalp will yield 100mg of hair, which is the standard sample size for screening and verification. For EtG, additional substances, and/or tests exceeding 10 panels, it is advisable to have 150mg of the sample. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair is not accessible, an equivalent amount of body hair can be used. References to head hair specifically denote scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The primary procedures in laboratory drug test analysis are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial integration of a sample into the laboratory’s system. This process includes confirming proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry omitted by an electronic chain of custody system.

Screening consists of a preliminary rapid assessment for substances of abuse. Although Screening is a cost-efficient method to exclude drug usage in the majority of samples, a positive screen needs verification for legal admissibility. Any samples that yield presumptive positive results in Screening necessitate an additional confirmation.

Upon a presumptive positive outcome in Screening, additional hair is extracted from the original specimen for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Verification of any positive screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before verification as needed. The entire laboratory workflow from Accessioning to Verification is reviewed under the CAP (College of American Pathologists) Hair designation and is accredited to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can identify drug usage for up to 90 days, whereas urine tests have a more confined detection window.
• Hard to falsify: It is exceedingly difficult to manipulate a hair drug test, ensuring more precise results.
• Records historical usage: It can reveal a pattern of drug use over time, not merely recent consumption.

Limitations:

• Cannot identify recent consumption: It takes about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests are typically costlier than other drug testing methods.
• Variability in outcomes: Factors like hair color and personal differences in hair growth can influence the level of drug metabolites in the hair.

Note: Although often termed as "hair follicle tests", the test itself assesses 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.
