Hair Follicle Drug Testing - Emerald Lake Hills, CA

What it is, How it works

Hair testing has gained a reputation as an effective means for identifying drug and alcohol consumption. Hair offers a comprehensive timeline of substance exposure by capturing biomarkers within its fibers as it grows. When gathered near the scalp, it can provide a detection span of up to 90 days for various substances. Hair sampling is straightforward, relatively tamper-resistant, and convenient for transportation.

Collecting a 1.5-inch bundle of approximately 200 hair strands (roughly the size of a #2 pencil) from the scalp yields 100mg of hair, making it the optimal quantity for both screening and validation. For EtG, additional tests, and tests exceeding 10 panels, a 150mg sample is advised. It is suggested to weigh the sample using a jeweler’s scale. In cases where scalp hair is not accessible, an equivalent amount of body hair can be used. References to head hair indicate scalp hair, whereas body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The lab processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the sample’s initial entry into the lab's system, ensuring it was correctly sealed and transported, assigning a LAN (Laboratory Accessioning Number), and performing any needed data entry not handled by an electronic chain of custody system.

Screening serves as a preliminary inspection for potential drug use. Though cost-efficient for initial assessment, a positive screening requires further validation for legal acceptance. Any samples yielding a presumptive positive during Screening necessitate a subsequent confirmation step.

In cases of presumptive positives during Screening, additional hair is extracted from the initial sample and prepared for the Extraction phase. At this stage, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), contributing to the complexity of hair drug testing.

GC/MS, GC/MS/MS, or LC/MS/MS methods are employed for confirming any positive screening outcomes. Before confirmation, all samples initially testing positive are thoroughly cleaned as necessary. The comprehensive lab procedure from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests reveal drug usage over 90 days, unlike the shorter timeframe of urine tests.
• Cheating deterrent: The challenge of cheating a hair drug test enhances result accuracy.
• Insightful data: They portray a prolonged drug use pattern, unlike tests limited to recent usage.

Limitations:

• Inability to detect immediate use: Detection in hair takes approximately 5-7 days post-exposure.
• Expense: Compared to other testing methods, hair drug tests generally incur higher costs.
• Outcome variations: Elements like hair color and personal hair growth differences can influence drug metabolite levels in hair.

Note: Despite common references to "hair follicle tests", the procedure examines the hair strand and not the sub-surface follicle.

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.
