Hair Follicle Drug Testing - New Market, PA

What it is, How it works

Hair testing is increasingly recognized as a robust method for assessing drug and alcohol consumption. Hair captures a prolonged history of substance use by embedding biomarkers in the strands as they grow. When collected near the scalp, hair offers about a 3-month detection timeframe for substances. Collection is straightforward, tampering is challenging, and shipping is convenient.

A sample comprising 1.5 inches and approximately 200 strands of hair (pencil-sized) near the scalp yields 100mg, which is the optimal quantity for initial screening and validation. For EtG, additional tests, or panels exceeding 10, 150mg is advised. It's best to measure the specimen using a jeweler’s scale. In the absence of scalp hair, body hair can be used. References to head hair mean scalp hair, whereas body hair includes all other types (e.g., facial, axillary).

Process Overview

The laboratory processing of a drug test result encompasses four major steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the part where a sample is first processed into the laboratory’s system. This step ensures the sample is sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry absent in an electronic chain of custody system.

Screening performs an initial rapid testing for substance abuse. Although Screening is a cost-efficient method to eliminate most drug usages, a positive result still requires confirmation for court admissibility. Presumptively positive samples from Screening need further validation.

If a sample is flagged as presumptively positive during Screening, additional hair is extracted from the initial sample for further preparation in Extraction. This involves retrieving drugs from hair at lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing the most complex method to execute.

Confirmation of positive screening results happens through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation, as necessary. The lab process, from Accessioning to Confirmation, adheres to standards by both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection timeline: Hair drug tests identify drug use for up to 90 days, unlike urine tests, which have limited detection periods.
• Challenging to fake: It’s highly difficult to undermine a hair drug test, ensuring accuracy of the results.
• Offers historical insight: It reveals a recurring pattern of substance usage over time rather than just recent consumption.

Limitations:

• Incapable of spotting recent use: It takes about 5-7 days for substances to show up in hair.
• Expense: Hair drug tests tend to be pricier compared to other testing methods.
• Result variations: Factors like hair color and individual hair growth rates can influence metabolite levels in the hair.

Note: Despite being dubbed "hair follicle tests", the examination focuses on the hair strand, 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.
