Hair Follicle Drug Testing - Charlestown, MD

What it is, How it works

Hair testing provides a robust mechanism for identifying drug and alcohol consumption. Hair captures long-term evidence of these substances by embedding biomarkers within the hair fiber during growth. When obtained near the scalp, hair offers a look-back window of up to three months for drug and alcohol detection. The sample is straightforward to gather, somewhat resistant to tampering, and convenient to ship.

A sample measuring 1.5 inches and comprising roughly 200 hair strands (similar to the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is optimal for screening and confirmation. For EtG, additional panels, or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest using a jeweler’s scale for weighing. If scalp hair is not available, a comparable body hair sample can be used. "Head hair" refers to scalp hair exclusively, whereas "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

The lab processing of drug tests encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where the sample is entered into the lab’s system. This involves confirming the sample’s seal and proper shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data not included in an electronic chain of custody.

Screening provides a preliminary check for drug use. Although it's a cost-efficient method for excluding drug use in most samples, a positive screen necessitates verification for legal admissibility. Presumptively positive samples from Screening must undergo further confirmation.

Upon a presumptive positive at the Screening phase, an additional hair portion is extracted from the initial sample for Extraction. Here, drugs are extracted at lower concentrations compared to other methods (e.g., urine or oral fluid), explaining why hair drug testing is particularly complex.

Confirmation for any positive Screening result employs GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positives undergo a necessary pre-confirmation wash. The complete lab process, from Accessioning to Confirmation, is scrutinized following the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair tests can track drug use over 90 days, in contrast to urine tests which have a shorter period.
• Hard to falsify: Cheating a hair drug test is challenging, increasing result reliability.
• Historical insight: It provides a record of drug use patterns rather than only recent consumption.

Limitations:

• Inability to detect recent use: Drugs take roughly 5-7 days to become evident in hair samples.
• Expense: Hair drug tests tend to be costlier than other testing forms.
• Result variability: Factors like hair color and individual growth variations can impact metabolite concentration in hair.

Note: Despite being called "hair follicle tests," the procedure examines the strand itself, 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.
