Hair Follicle Drug Testing - Blairstown, IA

What it is, How it works

Hair testing serves as an influential resource for identifying the use of drugs and alcohol. The fibers of hair incorporate biomarkers from substances over a prolonged timeframe, offering historical insights into drug and alcohol intake. When samples are taken near the scalp, they present a detection span of roughly three months for these substances. Hair collection is straightforward, hard to alter, and convenient to send.

A sample measuring 1.5 inches and containing about 200 strands (equivalent to the diameter of a #2 pencil) taken near the scalp yields approximately 100mg of hair, considered optimal for analysis and confirmation. For EtG, add-ons, or tests exceeding ten panels, collecting 150mg is suggested. We advise using a jeweler's scale to weigh the sample. If scalp hair cannot be obtained, a comparable amount of body hair is acceptable. 'Head hair' pertains to scalp hair, whereas 'body hair' encompasses other types (facial, axillary, etc.).

Process Overview

The lab processing of a drug test entails four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the primary step where a sample is documented into the lab's system. It involves ensuring that the sample is properly sealed and dispatched, generating a random LAN (Laboratory Accessioning Number), and completing any necessary data input not covered by an electronic chain of custody system.

Screening includes an initial examination for substance misuse. While it is a budget-friendly approach to exclude drug consumption in most samples, a positive screening necessitates confirmation to be valid in legal contexts. Samples that test tentatively positive in Screening must undergo further confirmation.

When a Screening phase indicates a presumptive positive, additional hair is extracted from the original sample for Extraction. This stage removes drugs from hair at concentrations lower than those used in other methods (e.g., urine or oral fluid), emphasizing the complexity of hair drug screening.

Confirmation of a positive screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, any samples with presumptive positives are washed as necessary. The whole lab procedure from Accessioning to Confirmation undergoes scrutiny, maintaining CAP (College of American Pathologists) Hair accreditation in addition to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests identify drug use for as long as 90 days, surpassing the shorter detection time of urine tests.
• Challenges to deception: The difficulty in manipulating a hair drug test enhances the reliability of results.
• Delivers historical insight: The test can reveal a timeline of drug consumption over a span, not solely recent intake.

Limitations:

• Inability to detect recent intake: Drugs become traceable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests generally incur higher costs than alternative testing methods.
• Outcome variability: Elements like hair color and individual hair growth rates can influence the drug metabolite levels in hair.

Note: Despite the term "hair follicle tests", this analysis examines the hair strand rather than 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. 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.
