Hair Follicle Drug Testing - Middle River, MD

What it is, How it works

Seen as a potent method for uncovering the use of drugs and alcohol, hair testing provides a comprehensive record of substance use by trapping biomarkers in the strands as the hair grows. When sourced from near the scalp, it can offer up to a 3-month detection period for both alcohol and other substances. Collection is straightforward, tampering is relatively difficult, and it’s easy to transport.

A sample of 1.5 inches, comprising approximately 200 strands (similar to a #2 pencil), taken from the scalp, yields 100mg of hair, optimal for screening and verification. For EtG and tests exceeding 10 panels, 150mg is suggested. Using a jeweler’s scale for measuring the specimen is advised. If scalp hair cannot be collected, a similar amount of body hair can be used. When we refer to head hair, it's purely about scalp hair. Other hair types, like facial or axillary, fall under body hair.

Process Overview

The lab steps for processing a drug testing result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates the initial intake of a sample into a lab’s system, confirming the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and finishing any missing data entry where the electronic chain of custody is inadequate.

Screening serves as a first-pass, efficient check for drug abuse. Although cost-effective, a positive result needs Confirmation for legal credibility. Samples that test positive during Screening require a subsequent confirmation.

Should a sample test positive in Screening, additional hair from the original specimen is used for Extraction. During this phase, drugs are drawn from hair at significantly lower concentrations than other methods such as urine or oral fluid, making this the toughest methodology for drug screening.

Confirmation of positive results utilizes GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are cleansed prior to confirmation as required. The full processing from Accessioning to Confirmation undergoes review in line with CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Prolonged detection period: Hair tests track drug usage for up to 90 days, whereas urine tests have a briefer detection timeframe.
• Hard to tamper with: Successfully cheating a hair drug test is difficult, enhancing result reliability.
• Offers historical insight: It illustrates a pattern of drug use over time, beyond just immediate use.

Limitations:

• Recent usage undetectable: Drugs take about 5-7 days to register in hair.
• Expense: Hair drug tests are costlier compared to other drug testing alternatives.
• Result variability: Elements like hair coloring and individual growth differences can impact detectable drug metabolite levels.

Note: Commonly termed "hair follicle tests,” the analysis actually evaluates the hair strand instead of the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Middle River, MD

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.
