Hair Follicle Drug Testing - Winston, OR

What it is, How it works

Hair examination is now recognized as an effective method for identifying substance and alcohol usage. Hair captures a prolonged history of these substances by embedding biomarkers within its growing strands. When obtained near the scalp, it can offer nearly a 3-month window for detecting drugs and alcohol. Collecting hair is straightforward, relatively resistant to tampering, and easily transportable.

A sample measuring 1.5 inches with approximately 200 strands (comparable in size to a #2 pencil) closest to the scalp yields 100mg, which is optimal for analysis and verification. For EtG, additional tests, or panels exceeding 10, a 150mg specimen is preferable. We advise using a jeweler’s scale for accuracy. If scalp hair isn’t accessible, equivalent body hair can be collected. Head hair refers specifically to scalp hair, while body hair includes all other types (facial, axillary, etc.).

Process Overview

The laboratory process for analyzing drug test results encompasses four main phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of integrating a sample into the lab’s system, confirming it was properly sealed and shipped, assigning a LAN (Laboratory Accessioning Number), and supplementing any data not included in an electronic chain of custody system.

Screening provides a preliminary assessment for substances of abuse. This method is a cost-effective means to exclude most samples from further review; however, if positive, additional confirmation is needed for legal purposes. Any Screening results that appear positive require another layer of verification.

For Screening-positives, further hair is extracted from the original sample and processed for Extraction. Here, drugs are isolated from hair in concentrations markedly lower than methods like urine or oral fluid testing, underscoring the complexity of hair drug screening.

Positive screenings undergo Confirmation with GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positives are cleaned before verification, as necessary. The complete lab workflow, from Accessioning to Confirmation, undergoes evaluation under the CAP (College of American Pathologists) Hair standard and complies with ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection duration: Hair tests can trace drug use for up to 90 days, unlike urine tests with shorter spans.
• Hard to manipulate: Cheating a hair drug test is challenging, thus increasing accuracy.
• Historical data provision: Offers insights into drug use patterns over time, not merely recent consumption.

Limitations:

• Incapable of spotting recent use: Drugs become noticeable in hair around 5-7 days post-use.
• Expense: Hair drug testing typically incurs higher costs than other methods.
• Result variability: Differences in hair color and personal hair growth rates can influence metabolite concentration in hair.

Note: Although often called "hair follicle tests", the analysis targets 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. 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. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols.
