Hair Follicle Drug Testing - Evergreen, MT

What it is, How it works

Hair testing is increasingly recognized as a robust method for detecting drug and alcohol consumption. It offers a comprehensive timeline of substance use, capturing biomarkers within the strands of growing hair. When sourced near the scalp, hair can indicate substance use for up to an approximate three-month period. Hair collection is straightforward, resistant to tampering, and easily transportable.

A 1.5-inch sample consisting of roughly 200 hair strands (equivalent to a #2 pencil in thickness) closest to the scalp is ideal for evaluation, providing 100mg of hair for effective screening and verification. For EtG, add-ons, and/or screenings exceeding 10 panels, a sample size of 150mg is suggested. It's advisable to weigh using a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair is acceptable. "Head hair" exclusively implies scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory analysis for drug testing involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the sample's initial integration into a lab's system, ensuring proper sealing and shipping. It includes assigning a LAN (Laboratory Accessioning Number) randomly and completing any extra information not provided electronically.

Screening offers a preliminary check for abused substances. Although Screening is a cost-effective measure to eliminate the presence of drug usage in most samples, a positive result necessitates further confirmation for legal accuracy. Any samples with a presumptive positive result during Screening must undergo an additional verification.

For samples with a presumptive positive result during Screening, further hair is extracted from the original sample for the Extraction process. This phase isolates drugs from hair at much lower concentrations than other methods (e.g., urine or oral fluid), establishing hair drug screening as the most challenging method to execute.

Confirmation of positive screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo a cleansing phase before confirmation if necessary. The whole laboratory procedure from Accessioning to Confirmation is inspected according to the CAP (College of American Pathologists) Hair standards and compliance with ISO / IEC 17025 regulations.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, whereas urine tests offer a shorter detection timeframe.
• Hard to circumvent: It's notably challenging to deceive a hair drug test, enhancing result accuracy.
• Historical insights: It offers insight into drug use patterns over a timeline, surpassing mere recent use detection.

Limitations:

• No recent detection: Drugs need around 5-7 days to become perceptible in hair.
• Expenses: Hair drug tests typically incur higher costs compared to other testing methods.
• Outcome discrepancies: Elements like hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Though often termed "hair follicle tests", the analysis targets the hair strand, 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.
