Hair Follicle Drug Testing - Oakdale, KY

What it is, How it works

Hair analysis has emerged as a potent method for identifying drug and alcohol consumption. Hair holds a prolonged history of substance use by capturing biomarkers within the fibers of the growing hair. When sampled near the scalp, hair can present up to around a 90-day detection span for substances. Hair collection is straightforward, challenging to tamper with, and easy to transport.

A sample measuring 1.5 inches with approximately 200 strands closest to the scalp equates to 100mg of hair, ideal for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, we suggest 150mg of the specimen. It’s advisable to weigh the sample on a jeweler’s scale. If scalp hair isn’t available, a similar quantity of body hair can be used. When we mention head hair, we specifically mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The primary steps in a lab's drug testing procedure include Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the initial acceptance of a sample into a laboratory's system. This includes ensuring the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any further data entry absent from an electronic chain of custody system.

Screening represents a preliminary swift examination for substance abuse. Although Screening serves as a cost-effective approach for discounting drug use in most samples, a positive screen requires confirmation for legal admissibility. All samples potentially positive in Screening necessitate secondary confirmation.

If a sample appears positive during the Screening phase, additional hair is taken from the original sample for Extraction. Here, substances are extracted from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), explaining why hair drug testing is the most challenging methodology to conduct.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are washed as needed. The whole laboratory procedure from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug examinations can identify substance use up to 90 days, unlike urine tests which have a more limited detection period.
• Hard to manipulate: Cheating a hair drug test is extremely difficult, thus enhancing the accuracy of results.
• Historical insight: It provides a record of drug use over time, rather than just recent usage.

Limitations:

• Cannot detect immediate use: It generally takes about 5-7 days for substances to become detectable in hair.
• Expense: Hair drug tests tend to be pricier than alternative drug testing techniques.
• Result variations: Variables such as hair color and individual differences in hair growth can impact the drug metabolite concentration in hair.

Note: Although commonly called "hair follicle tests", the test actually examines the hair strand and 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.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings.
