Hair Follicle Drug Testing - Poplar Grove, AR

What it is, How it works

Hair analysis is now recognized as a potent method for identifying alcohol and drug consumption. Hair captures biomarkers within the fibers of the growing strand, providing an extended history of alcohol and drug use. When gathered near the scalp, hair may reveal up to a roughly 3-month span for alcohol and drug detection. Collecting hair is straightforward, challenging to tamper with, and simple to send.

A 1.5-inch segment consisting of about 200 hair strands (approximately the same thickness as a #2 pencil) closest to the scalp yields 100mg of hair, which is the perfect amount for initial testing and verification. For tests involving EtG add-ons or more than 10 panels, a sample of 150mg is suggested. Using a jeweler's scale to weigh the hair is advisable. If scalp hair is unavailable, a corresponding quantity of body hair can be used. When mentioning head hair, we refer exclusively to scalp hair, whereas body hair includes all other hair types (like facial, axillary, etc.).

Process Overview

The primary steps in lab processing of drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first stage where a sample is processed into a lab’s system. This step entails ensuring the sample's secure seal and proper shipment, assigning a random Laboratory Accessioning Number (LAN), and finalizing any additional data input not handled by an electronic custody chain system.

Screening is a preliminary rapid check for substance abuse. Although Screening is a cost-efficient way to rule out drug presence in most samples, a positive screen needs confirmation to be legally valid. Any samples that test potentially positive during Screening must undergo secondary confirmation.

If a sample shows a positive result initially in Screening, more hair is retrieved from the original sample for Extraction. This phase involves extracting drugs from hair at substantially lower concentrations compared to other techniques like urine or oral fluid testing, making hair drug screening the most challenging method to execute.

Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed prior to confirmation as necessary. The complete lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Prolonged detection period: Hair tests can identify drug usage for up to 90 days, unlike urine tests with shorter detection durations.
• Challenging to falsify: It is particularly difficult to deceive a hair drug test, enhancing the reliability of results.
• Retrospective data: Offers a record of drug use over time, not limited to immediate past usage.

Limitations:

• Inability to detect recent usage: Drugs typically become detectable in hair after about 5-7 days.
• Expense: Hair drug tests are generally costlier than other drug testing approaches.
• Result variations: Elements such as hair color and individual differences in hair growth can impact the levels of drug metabolites found in hair.

Note: Often dubbed "hair follicle tests," the evaluation focuses on the hair strand rather than 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.
