Hair Follicle Drug Testing - Granville, VT

What it is, How it works

Hair testing is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair traps biomarkers within its strands, offering an extended timeline for alcohol and drug detection. When acquiring samples near the scalp, hair can reveal drug and alcohol use for as long as three months. The sample collection process is user-friendly, hard to tamper with, and straightforward to transport.

A 1.5-inch portion consisting of roughly 200 hair strands (comparable to a #2 pencil) closest to the scalp yields 100mg, which is the perfect amount for screening and verification. For tests like EtG, additional panels, or those exceeding 10 panels, a 150mg sample is advised. We suggest using a jeweler’s scale for accurate weighing. In cases where scalp hair isn't available, an equivalent amount of body hair is acceptable. References to head hair specifically denote scalp hair, whereas body hair includes other types (facial, axillary, etc.).

Process Overview

The laboratory examination of a drug test result is segmented into four core phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the incorporation of a sample into the lab's system, ensuring the sample’s seal and shipment are intact, generating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent from an electronic chain of custody protocol.

Screening performs an initial rapid examination for illicit drugs. While Screening provides a budget-friendly way to dismiss drug presence in the majority of samples, a positive result mandates confirmation for court acceptability. Samples with presumptive positive outcomes in Screening necessitate a follow-up confirmation.

If Screening indicates a presumptive positive, additional hair from the existing sample is prepared for the Extraction phase. During Extraction, drugs are drawn out of the hair at lower concentrations compared to other techniques (e.g., urine or oral fluid), thus, hair drug screening presents the most complexity.

Positive Screening results require Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptively positive samples undergo cleansing before Confirmation as needed. The overarching laboratory process from Accessioning to Confirmation is under scrutiny from both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accrediting criteria.

Advantages of hair drug testing:

• Long detection window: Hair drug tests reveal drug use spanning up to 90 days, surpassing the shorter window of urine tests.
• Difficulty to cheat: Manipulating a hair drug test is notably challenging, thereby ensuring more precise results.
• Provides historical data: It delivers a timeline of substance use, rather than focusing solely on recent consumption.

Limitations:

• Cannot detect recent use: Detection in hair requires approximately 5-7 days from drug intake.
• Cost: Hair drug testing is typically pricier compared to alternative drug testing methods.
• Variations in results: Elements such as hair color or personal hair growth rates may influence drug metabolite levels in hair.

Note: Though commonly labeled as "hair follicle tests", the procedure evaluates the hair strand rather than the hair 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.
