Hair Follicle Drug Testing - Brodnax, VA

What it is, How it works

Hair analysis is now recognized as an effective means for detecting drug and alcohol consumption. Hair can reveal a lengthy usage history by retaining biomarkers within the strands as they grow. When collected near the scalp, it can provide a detection timeframe of roughly 3 months for both alcohol and drugs. Hair collection is straightforward, hard to tamper with, and easy to transport.

A 1.5-inch hair sample consisting of roughly 200 strands (approximately the width of a #2 pencil) closest to the scalp will yield 100mg, an optimal amount for both screening and confirmation. When conducting EtG, add-ons, or tests beyond 10 panels, 150mg is advisable. It is suggested to weigh the sample on a jeweler’s scale. If scalp hair cannot be used, an equivalent quantity of body hair may be gathered. When referring to head hair, this indicates only scalp hair. Body hair encompasses all other types, including facial and axillary.

Process Overview

The primary phases in laboratory processing of a drug test include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the sample's initial integration into the laboratory system. This phase ensures proper sealing and shipping, assigns a LAN (Laboratory Accessioning Number), and finalizes any further data entry absent from an electronic chain of custody.

Screening is a preliminary check for drug presence. While being a cost-efficient method for ruling out drug use in most samples, a positive result necessitates confirmation for court admissibility. Presumptively positive samples in Screening require secondary confirmation.

In cases of presumptive positivity during Screening, additional hair is extracted from the original sample for the Extraction process. Here, drugs are extracted at significantly lower concentrations compared to other methods like urine or oral fluids, making hair drug screening particularly complex.

All positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation as required. From Accessioning to Confirmation, the lab processes are examined under both the CAP Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair tests can trace drug usage for up to 90 days, unlike urine tests which have a shorter timeframe.
• Hard to manipulate: Hair tests are difficult to cheat, enhancing result accuracy.
• Historical data: They reveal a usage pattern over time, beyond just recent consumption.

Limitations:

• Inability to detect recent use: Drugs typically become detectable in hair after about 5-7 days.
• Cost: Hair testing generally incurs higher costs than other testing types.
• Result variations: Factors such as hair color and growth differences can impact drug metabolite concentration in hair.

Note: Although frequently called "hair follicle tests," they analyze 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. 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.
