Hair Follicle Drug Testing - La Porte City, IA

What it is, How it works

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. The hair fiber encases biomarkers within the strands, offering a prolonged view of alcohol and drug usage. Hair collected near the scalp can yield a detection window of up to three months for substance use. The collection process is straightforward, the potential for tampering is minimal, and it’s convenient to transport.

A sample measuring 1.5 inches, comprised of approximately 200 hair strands (equivalent to the girth of a #2 pencil), will weigh roughly 100mg, which is ideal for both screening and confirmation testing. For EtG, additional tests, or panels exceeding ten, a specimen weight of 150mg is suggested. Utilizing a jeweler’s scale for measuring the specimen is advised. If scalp hair is unobtainable, a comparable volume of body hair can be used. 'Head hair' specifically refers to scalp hair, while 'body hair' encompasses all other types (facial, axillary, etc.).

Process Overview

The lab process for drug test results involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where a sample is integrated into the lab’s system, verifying that appropriate sealing and shipping occurred, a random LAN (Laboratory Accessioning Number) is assigned, and completing any missing details not covered by an electronic chain of custody.

Screening is a preliminary assessment for drug presence. Though cost-efficient and effective for many samples, positive Screening results need further confirmation to be considered legally valid. Presumptive positive findings in Screening require subsequent confirmation.

In cases of presumptive positivity during Screening, additional hair is extracted from the initial sample for Extraction. Here, drug extraction from hair is performed at much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug analysis the most complex to execute.

Confirmation of any positive Screened results is performed using GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples undergo a pre-confirmation wash if necessary. The entire process from Accessioning to Confirmation adheres to review protocols, including CAP (College of American Pathologists) Hair standards and compliance with ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can reveal substance use for up to 90 days, whereas urine tests detect a more limited timeframe.
• High resistance to manipulation: Hair drug tests offer more reliable results due to difficulty in tampering.
• Historic usage overview: Provides insights into drug use patterns over time, rather than just recent intake.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Higher cost: Typically more costly than alternative drug testing methods.
• Variable results: Differences such as hair color and personal hair growth rates can influence drug metabolite levels in hair.

Note: Although commonly termed "hair follicle tests," this analysis targets the hair shaft and does not involve 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.
