Hair Follicle Drug Testing - Island City, OR

What it is, How it works

Hair testing is now recognized as an effective method for detecting drugs and alcohol. The hair encapsulates biomarkers within its strands, offering a historical record of substance use. When the hair is sourced near the scalp, it typically provides a detection window of up to three months for alcohol and drugs. The collection process is straightforward, with a low risk of tampering and easy transportation.

A 1.5-inch hair sample comprising approximately 200 strands (comparable to a #2 pencil's thickness) near the scalp yields 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, or tests beyond 10 panels, a specimen of 150mg is suggested. Utilizing a jeweler’s scale to measure the specimen is advised. Should scalp hair not be accessible, an equivalent quantity of body hair can be used. “Head hair” refers specifically to scalp hair only, while “body hair” encompasses all other hair varieties (such as facial and axillary hair).

Process Overview

The laboratory processing of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial phase of integrating a sample into a lab’s system. This phase ensures the sample’s seal and shipment integrity, assigns it a LAN (Laboratory Accessioning Number), and records any supplementary data that an electronic chain of custody system might not provide.

Screening serves as an initial, swift assessment for drug presence. Although cost-effective for excluding drug use in many samples, a positive screen must be validated to be legally permissible. Samples showing presumptive positivity in Screening necessitate subsequent confirmation.

In cases of presumptive positive results during Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are drawn out from hair at notably lower concentrations than in other methods (like urine or oral fluid), rendering hair drug screening the most challenging method to execute.

Confirmation of any positive screening outcome utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing as necessary before confirmation. From Accessioning to Confirmation, the entire lab process undergoes scrutiny under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection duration: Hair drug testing identifies drug use for up to 90 days, whereas urine testing offers a more limited detection timeframe.
• Hard to circumvent: Hair drug tests are resistant to adulteration, enhancing result reliability.
• Tracks historical usage: It charts a timeline of drug use, rather than merely recent consumption.

Limitations:

• Unable to detect recent consumption: Drugs commence detectability in hair roughly 5-7 days post-use.
• Expense: Hair drug testing often incurs higher costs compared to alternatives.
• Result variability: Hair color and personal hair growth discrepancies can influence drug metabolite concentrations.

Note: Commonly termed "hair follicle tests," the analysis targets the hair strand itself, not the beneath scalp 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. 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.
