Hair Follicle Drug Testing - Pleasanton, NE

What it is, How it works

Recognized as a potent method, hair testing unveils drug and alcohol utilization. It captures a long-term record of substance use by embedding biomarkers within the fibers of the hair strand in growth. When sampled near the scalp, hair can reflect a 3-month period of alcohol and drug detection. Its collection is straightforward, somewhat resistant to tampering, and convenient for transport.

A 1.5-inch cut of approximately 200 hair strands (resembling the thickness of a #2 pencil) nearest the scalp yields 100mg of hair, which is the perfect amount for both screening and verification. For testing parameters such as EtG, additional metrics, and/or panels exceeding 10, a 150mg sample is advisable. We propose using a jeweler’s scale for precise measurement. If scalp hair is unavailable, an equivalent amount of body hair should be collected. By head hair, we specify only scalp hair. Body hair encompasses all other forms (such as facial, axillary, etc.).

Process Overview

The drug test laboratory procedure involves four pivotal phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the sample's initial entry into the laboratory’s records. This encompasses validating the integrity of the sample's seal and shipping protocol, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplemental data input missing from an electronic custody documentation process.

Screening performs a preliminary evaluation for drug presence. It is a cost-effective approach to deter drug consumption in numerous samples. However, legal usability requires confirmation of any positive screen results. Any samples that preliminarily test positive during Screening necessitate secondary validation.

For samples that return a positive Screening result, more hair is extracted from the original batch and readied for Extraction. Here, drugs are extracted from hair at lower concentrations compared to alternative methods (e.g., urine, oral fluid), highlighting hair drug screening as a challenging technique to execute.

Verification of positive screening outcomes is done through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples with presumptive positive results are washed if necessary. From Accessioning to Confirmation, every stage undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and meets ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can recognize drug use up to 90 days, contrasting with urine tests that offer a shorter detection timeframe.
• Hard to manipulate: It is substantially difficult to falsify a hair drug test, enhancing the precision of results.
• Reveals usage patterns: It provides a chronological record of drug use over time, beyond just recent intake.

Limitations:

• Inability to detect recent use: Detection of drugs in hair takes about 5-7 days to manifest.
• Expense: Hair drug tests tend to be pricier than other testing options.
• Variability in results: Elements such as hair color and individual hair growth patterns can impact drug metabolite concentrations within hair.

Note: Commonly termed as "hair follicle tests", the analysis focuses on the hair strand and 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.
