Hair Follicle Drug Testing - Powhatan, LA

What it is, How it works

Hair analysis is now recognized as a potent method for identifying drug and alcohol consumption. Hair offers a chronicling of alcohol and substances by encasing biomarkers within the hair's fibrous structure as it grows. When sourced near the scalp, it can reveal substance use within a span of up to three months. Hair collection is straightforward, relatively tamper-resistant, and convenient for shipping.

A 1.5-inch cut of roughly 200 hair strands (approximating the width of a #2 pencil) nearest the scalp yields 100mg, which is optimal for diagnostic and confirmatory analysis. For EtG, supplementary evaluations, and/or panels exceeding 10, 150mg of the sample is advised. It's recommended to measure the sample with a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair may be gathered. References to head hair specifically denote scalp hair, while body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The key procedures in lab processing for a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning starts with the sample's entry into a lab system. It comprises verifying correct sample sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data required not covered by an electronic chain of custody system.

Screening entails a preliminary check for narcotics. Though Screening is cost-effective for eliminating drug use in most cases, a positive screen needs corroboration for legal admissibility. Any samples testing positive require further confirmation.

If a sample tests positive at the Screening stage, additional hair is extracted from the initial sample and prepared for Extraction. This step involves extracting drugs from hair at concentrations much lower than in other testing methods (e.g., urine or oral fluids); hence, hair drug screening is notably complex.

Confirmation of a positive screen is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmatory testing as necessary. The comprehensive lab protocol from Accessioning to Confirmation is evaluated in accordance with both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can uncover drug usage up to 90 days prior, whereas urine tests have a briefer detection span.
• High resistance to falsification: It is extremely challenging to falsify a hair drug test, enhancing result authenticity.
• Reveals historical consumption data: The test highlights a pattern of drug use over time, not merely recent consumption.

Limitations:

• Cannot identify recent usage: Drug presence in hair becomes detectable only after 5-7 days.
• Expense: Hair drug testing tends to be pricier than alternative drug testing approaches.
• Result discrepancies: Variables like hair color and individual differences in hair growth can influence metabolite concentration in hair.

Note: Although often called "hair follicle tests", the examination itself involves hair strands rather than the scalp-contained follicle.

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.
