Hair Follicle Drug Testing - Reads Landing, MN

What it is, How it works

Hair testing is regarded as a robust method for identifying drug and alcohol consumption. Hair offers an extensive history of substance use by capturing biomarkers within the fibers of the developing hair strand. When sourced near the scalp, hair can provide an approximate 3-month period of detection for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and convenient to transport.

A 1.5-inch section of roughly 200 hair strands (comparable to a #2 pencil) from near the scalp yields 100mg of hair, which is optimal for screening and confirmation. For EtG, additional tests, or panels exceeding 10, 150mg of the specimen is advised. We suggest utilizing a jeweler’s scale for weighing the specimen. If scalp hair is absent, a similar amount of body hair can be gathered. When mentioning head hair, we specifically mean scalp hair. Body hair denotes all other hair types, such as facial or axillary hair.

Overview of the Process

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

Accessioning encompasses the sample's preliminary processing into a lab's system. This step verifies that the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and finalizes any data entry missing from an electronic chain of custody system.

Screening is an initial basic check for drug presence. While cost-effective for excluding drug use in most samples, a positive screening requires confirmation for court admissibility. Presumptively positive samples from Screening necessitate a subsequent confirmation.

For samples that are presumptively positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. In this phase, drugs are isolated from hair at much lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing exceptionally challenging to execute.

Any confirmed positive results undergo verification using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are cleansed as needed. The laboratory's entire operation from Accessioning to Confirmation is assessed following both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for as long as 90 days, whereas urine tests have a shorter detection span.
• Hard to manipulate: It is notably challenging to modify a hair drug test, enhancing result reliability.
• Delivers historical insight: It can reflect a pattern of drug use over time, not merely recent consumption.

Drawbacks:

• Inability to detect recent use: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests typically cost more than alternative drug testing approaches.
• Result variability: Elements like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Though frequently called "hair follicle tests," the test evaluates 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. 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. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation.
