Hair Follicle Drug Testing - Sandyville, WV

What it is, How it works

Hair evaluations have gained recognition as an effective method for identifying alcohol and drug consumption. Hair captures a prolonged record of drug and alcohol usage by embedding biomarkers within the fibers of the hair strand as it grows. When collected near the scalp, hair offers a detection window of approximately three months for alcohol and other substances. Collecting hair is straightforward, making it harder to tamper with, and easy to transport.

A sample of 1.5 inches consisting of around 200 strands near the scalp (similar to the diameter of a #2 pencil) will yield 100mg of hair, which is the optimal sample size for screening and confirmation purposes. For EtG, additional tests, or tests with more than 10 panels, a 150mg sample is advised. It's beneficial to weigh the hair sample with a jeweler’s scale. If scalp hair isn't an option, a similar quantity of body hair may be used. When discussing head hair, we specifically mean scalp hair. Body hair encompasses other types like facial and axillary hair.

Process Overview

The primary phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial insertion of the sample into the laboratory’s system, where the sample's proper sealing and shipping are checked, a random LAN (Laboratory Accessioning Number) is assigned, and any further data not given digitally is entered manually.

Screening executes an initial rapid check for drug misuse. Though it efficiently rules out drug use in most samples, a positive screen necessitates further confirmation for legal acceptability. Presumptive positive samples from Screening must undergo secondary confirmation.

For positively presumed samples in the Screening phase, additional hair is extracted from the original specimen for the Extraction stage. Here, drugs are separated from hair at significantly lower concentrations than other methods like urine or oral fluids, which contributes to the challenge of hair drug screening processes.

Positive results from Screening undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. If necessary, all samples with presumptive positives are cleansed prior to confirmation. The entire process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter timeframe.
• Difficulty in manipulation: Its results are precise due to the challenge of tampering with a hair drug test.
• Yields historical patterns: It reveals drug usage patterns over time, not just recent instances.

Limitations:

• Limited recent detection: Drugs take about 5-7 days to appear in hair samples.
• Higher expenses: Hair drug tests typically cost more than other testing methods.
• Result variability: Elements like hair pigmentation and individual growth rates can influence drug metabolite concentrations in hair.

Note: Although commonly termed as "hair follicle tests", the test actually examines the strand of hair, 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.
