Hair Follicle Drug Testing - Carmen, AZ

What it is, How it works

The utilization of hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair encapsulates a prolonged record of such use by locking biomarkers within the fibers of the burgeoning hair strand. When sourced near the scalp, hair can reveal substance use for up to about three months, demonstrating its effectiveness in detection. The collection process for hair is straightforward, poses challenges for tampering, and is convenient for shipping.

A sample measuring 1.5 inches, comprising roughly 200 hair strands (equivalent to the diameter of a #2 pencil) nearest to the scalp, provides 100mg of hair, which is optimal for conducting screenings and confirming results. For EtG, additional tests, and/or analyses exceeding 10 panels, it is advisable to use 150mg of the sample. Utilizing a jeweler's scale to weigh the specimen is recommended. Should scalp hair be unavailable, gathering an equivalent amount of body hair is an option. When discussing head hair, we specifically refer to scalp hair. Conversely, body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The key stages in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the preliminary handling of a sample within a lab's framework. This step ensures that the sample was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry not included in an electronic chain of custody system.

Screening involves an initial rapid assessment for drugs of misuse. Although Screening provides a cost-efficient means to exclude drug usage for most samples, a positive result requires Confirmation to be valid for legal proceedings. Samples with a presumptive positive result from Screening necessitate additional confirmation.

If a sample returns a presumptive positive during Screening, further hair is extracted from the initial sample and prepared for Extraction. In this phase, drugs are isolated from hair at a significantly reduced concentration compared to other methods (e.g., urine or oral fluid), emphasizing the complexity of hair drug screening.

Confirmation of any positive screening is achieved via methods like GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positivity are cleansed prior to Confirmation when necessary. The comprehensive laboratory process, from Accessioning to Confirmation, is examined under the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug screenings can identify drug use for up to 90 days, compared to urine screenings with a more limited detection period.
• Resistant to tampering: Hair drug tests are notably resistant to manipulation, enhancing the accuracy of outcomes.
• Historical usage pattern: These tests can illustrate a pattern of drug use over time, beyond immediate consumption.

Limitations:

• Inability to identify recent usage: Drugs generally take about 5-7 days to become detectable in hair.
• Expense: Hair drug screenings usually incur higher costs than other testing approaches.
• Result variability: Factors such as hair color and differences in individual hair growth can influence drug metabolite concentrations in hair.

Note: While commonly termed "hair follicle tests," the process evaluates the hair strand itself, 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.
