Hair Follicle Drug Testing - Green Valley, MD

What it is, How it works

The use of hair testing has emerged as a robust method for identifying drug and alcohol consumption. By encasing biomarkers within the hair shaft, hair reveals an extended history of substance use. A sample gathered near the scalp can reflect drug and alcohol intake for up to about 90 days. Hair collection is straightforward, tampering is relatively tough, and it is effortlessly transportable.

An ideal hair sample consists of a 1.5-inch section of roughly 200 hairs (comparable in size to a #2 pencil) nearest to the scalp, yielding 100mg of hair suitable for both screening and confirmation. For EtG, add-ons, and/or substances exceeding 10 panels, a sample of 150mg is suggested. It's beneficial to measure the sample using a jeweler’s scale. If scalp hair is inaccessible, an equivalent quantity of body hair may be used. "Head hair" specifies only the hair on the scalp. "Body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

The four fundamental phases in scientifically evaluating a drug test are Accessioning, Screening, Extraction, and Confirmation.

Initially, Accessioning processes the sample into a laboratory's system by confirming proper sealing and shipping, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any extra data entry absent in an electronic chain of custody framework.

Screening serves as a preliminary assessment for drug presence. Although cost-effective for eliminating drug usage in most cases, a positive screen mandates verification for legal acceptability. Samples indicating presumptive positives require a follow-up confirmation.

If a screen reveals a presumptive positive, additional hair is extracted from the initial sample and made ready for Extraction. Here, substances are drawn out of hair at a significantly lesser concentration compared to alternate methods (e.g., urine or oral fluid), establishing hair drug screening as the most complex method to execute.

Positive screening confirmations utilize GC/MS, GC/MS/MS or LC/MS/MS. All positive samples undergo pre-confirmation washing as necessary. The lab process from Accessioning to Confirmation adheres to scrutiny under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 certification.

Advantages of hair drug testing:

• Extended detection span: Capable of detecting drugs for up to 90 days, unlike urine tests which have a shorter detection range.
• Resistant to tampering: Hair drug tests are challenging to falsify, ensuring result accuracy.
• Historical insight: Provides an overview of drug usage over time, not merely recent consumption.

Limitations:

• Lacks recent detection: Substances typically become detectable in hair after about 5-7 days.
• Expense: Hair tests generally incur higher costs compared to other testing methods.
• Result diversity: Variables such as hair color and personal growth rates can impact drug metabolite concentration within hair.

Note: Despite the term "hair follicle tests", the analysis 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.
