Hair Follicle Drug Testing - Elkton, OR

What it is, How it works

Hair analysis is recognized as an effective means for identifying the consumption of drugs and alcohol. Hair retains a comprehensive history of alcohol and drug use by capturing biomarkers within the growing strand's fibers. When collected near the scalp, hair can offer a detection window of up to roughly 3 months for alcohol and drugs. Hair collection is straightforward, relatively challenging to tamper with, and convenient to transport.

A 1.5-inch segment containing around 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal sample size for testing and validation. For EtG, add-ons, and/or analyses beyond 10 panels, 150mg of the sample is advisable. We propose using a jeweler’s scale to weigh the sample. If scalp hair is unavailable, a comparable quantity of body hair may be obtained. When addressing head hair, it specifically refers to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory handling of a drug test result comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary integration of a sample into a laboratory's process. This step involves confirming that the sample was adequately sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and entering any additional information absent from an electronic chain of custody system.

Screening consists of an initial rapid assessment for substances of abuse. Screening offers a cost-effective method to exclude drug usage in most samples, but a positive screened result must undergo confirmation to be court-admissible. Samples that are tentatively positive during Screening necessitate an additional confirmation.

If a sample appears presumptively positive at the Screening phase, more hair is extracted from the original sample and prepared for Extraction. During this stage, drugs are isolated from hair at a substantially lower concentration compared to other practices (e.g., urine or oral fluid), which is why hair drug testing is the most challenging procedure to execute.

Confirmation of any positive screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptive positive undergo necessary washing before confirmation. The comprehensive laboratory process from Accessioning to Confirmation is evaluated under 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 assessments can reveal drug usage for up to 90 days, unlike urine tests which have a shorter detection span.
• Hard to manipulate: Cheating a hair drug test is extremely difficult, thereby enhancing accuracy.
• Historical insight: It offers a timeline of drug use over an extended period, not just recent consumption.

Limitations:

• Inability to detect recent consumption: Drugs require approximately 5-7 days to become detectable in hair.
• Expense: Hair drug assessments are typically more costly than other drug testing approaches.
• Result variability: Factors like hair color and individual growth rates can influence metabolite concentrations in hair.

Note: Although often termed "hair follicle tests", the analysis is on the hair strand, not the follicle underneath 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.
