Hair Follicle Drug Testing - Charlotte, NC

What it is, How it works

Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. The hair captures long-term evidence of substances by embedding biomarkers within the strands as they grow. Sampling close to the scalp can offer nearly a 3-month detection period for substances. Hair is straightforward to gather, resistant to tampering, and easily transported.

Obtaining a 1.5-inch cut of around 200 hair strands (roughly the thickness of a #2 pencil) nearest the scalp will yield the optimal 100mg sample for testing and validation. For tests like EtG, supplementary analyses, and panels exceeding 10, 150mg is preferred. It's advisable to measure the amount using a jeweler’s balance. If scalp hair isn't accessible, a comparable amount of body hair can be taken. When discussing head hair, it pertains strictly to scalp hair. Body hair includes all other forms (facial, axillary, etc.).

Process Overview

The examination of a drug test sample in the lab encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial entry of the sample into the lab's system, ensuring it was sealed and dispatched correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any missing data not available from an electronic custody chain.

Screening offers a swift preliminary check for drug residues. Though it's a cost-efficient tactic for eliminating drug presence in the bulk of samples, a positive screening result must be verified for legal acceptability. Any specimens identified as positive during screening require additional confirmation.

Should the initial Screening imply a positive result, extra hair is extracted from the main sample for the Extraction process. Here, drugs are isolated from hair in significantly lower concentrations compared to other techniques (like urine or saliva), which is why hair testing is particularly challenging.

Verification of any positive screened outcome is carried out through GC/MS, GC/MS/MS, or LC/MS/MS methods. Samples with presumptive positives are cleaned before confirmation as necessary. The comprehensive lab procedure, from Accessioning through to Confirmation, is inspected under both the CAP (College of American Pathologists) Hair designation and certified to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection duration: Hair tests can trace drug consumption for up to 90 days, while urine tests have a limited detection span.
• Challenge to deceive: Hair testing is quite hard to manipulate, resulting in more dependable outcomes.
• Offers historical insight: It reveals a timeline of drug consumption over time, beyond just recent usage.

Limitations:

• Inability to indicate recent intake: It takes roughly 5-7 days before drugs appear in hair.
• Expense: Hair analysis is typically pricier than alternative drug testing forms.
• Result variability: Elements such as hair color and personal differences in hair growth can influence drug metabolite levels in the hair.

Note: Although commonly referred to as "hair follicle tests", the analysis is conducted on the hair strand itself, not the follicle beneath the skin.

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.
