Hair Follicle Drug Testing - Forrest City, AR

What it is, How it works

Hair tests have gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of alcohol and drug intake by embedding biomarkers within the strand’s fibers as it grows. When obtained near the scalp, hair can offer nearly a 3-month detection span for drugs and alcohol. It is straightforward to collect, hard to tamper with, and convenient to transport.

A 1.5-inch segment of around 200 hair strands (approximately the size of a #2 pencil) nearest the scalp will yield 100mg of hair, which is the optimal amount for testing and confirmation. For tests including EtG, add-ons, or more than 10 panels, 150mg of the sample is advisable. We suggest using a jeweler's scale for specimen measurement. Should scalp hair be inaccessible, a similar quantity of body hair can be used. When mentioning head hair, we refer solely to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Procedure Outline

The four principal phases in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a lab’s system. This process verifies the proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any further data entry absent from an electronic chain of custody system.

Screening performs an immediate evaluation for drug abuse. Although Screening efficiently eliminates drug use in most samples, any positive screen requires Confirmation to be legally valid. Presumptive positives in Screening demand secondary Confirmation.

For samples yielding a presumptive positive during Screening, additional hair is extracted from the initial sample and prepped for Extraction. In this step, drugs are isolated from hair at a markedly lower concentration than other methods (such as urine or oral fluid), highlighting why hair drug testing ranks as the most challenging methodology.

Confirmation of any screened positive is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples undergo washing, if necessary, before Confirmation. The entire lab process from Accessioning to Confirmation receives oversight by both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Benefits of hair drug testing:

• Extended detection period: Hair tests reveal drug use for up to 90 days, unlike urine tests which offer a reduced detection period.
• Cheating difficulty: Tampering with hair drug tests is notably challenging, enhancing accuracy.
• Historical insight: Provides a usage pattern over time, not merely recent intake.

Drawbacks:

• Inability to detect recent intake: Drugs require around 5-7 days to become noticeable in hair.
• Expense: Hair tests typically cost more than other drug testing methods.
• Result variability: Drug metabolite concentrations in hair might be influenced by factors like hair color and individual growth variations.

Note: Commonly termed "hair follicle tests", the assessment examines the hair strand rather than the hair 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.
