Hair Follicle Drug Testing - Oakville, LA

What it is, How it works

Hair testing is increasingly recognized as an effective means for identifying drug and alcohol consumption. By capturing biomarkers within the strands, hair offers a long-term record of substance use. When cut near the scalp, it can reflect alcohol and drug usage over a span of up to three months. Hair samples are straightforward to collect, challenging to tamper with, and are straightforward for shipping.

A sample measuring 1.5 inches consisting of roughly 200 hair strands, akin to the thickness of a #2 pencil, provides about 100mg—perfect for screening and confirmation. For EtG, additional tests, or panels exceeding 10, a specimen amount of 150mg is advisable. We suggest using a jeweler's scale for weighing the sample. In the absence of scalp hair, an equivalent measure of body hair can be used. 'Head hair' pertains solely to scalp hair, while 'body hair' encompasses all other types (facial, axillary, etc.).

Process Overview

Laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, a sample is initially managed within the lab's system by confirming its proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing any pending information not input electronically.

Screening is a preliminary check for drug abuse and serves as a cost-effective measure to largely rule out drug presence. However, a positive result requires confirmation to be court-admissible. Samples indicating presumptive positives need secondary verification.

If the Screening stage yields a presumptive positive, additional hair is taken from the initial sample for Extraction. Here, substances are extracted at lower concentrations compared to other methods (like urine or oral fluids), highlighting the complexity of hair drug screening.

Any positive results from the screening are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed as necessary before confirmation. The whole lab process, from Accessioning to Confirmation, is reviewed under CAP (College of American Pathologists) Hair standards and involves ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests capture substance use over approximately 90 days, whereas urine tests offer a shorter window.
• Challenge to falsify: Cheating a hair drug test is notably difficult, enhancing result accuracy.
• Historic usage data: Offers insights into substance consumption patterns over time, rather than just recent activities.

Limitations:

• Inability to detect recent intake: Drugs typically become detectable in hair after 5-7 days.
• Expense: Hair drug tests tend to be costlier than other formats.
• Inconsistent results: Hair color variations and personal hair growth differences might affect metabolite concentrations in hair.

Note: Often termed as "hair follicle tests", the test evaluates the hair strand itself rather than 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.
