Hair Follicle Drug Testing - Pinesburg, MD

What it is, How it works

Hair assessments have emerged as an effective method for identifying drug and alcohol consumption. By encapsulating biomarkers within the strands' fibers, hair offers an extended timeline of substance usage. Collected near the scalp, hair samples can track substance consumption for approximately three months. The process of obtaining hair samples is straightforward, challenging to tamper with, and convenient for shipping.

A sample measuring 1.5 inches, comprising roughly 200 strands (equivalent to a #2 pencil), yields 100mg of hair—ideal for both initial tests and confirmations. For EtG, additional requirements, and extensive tests exceeding ten panels, it's advisable to collect 150mg. Using a jeweler’s scale for precise weighing is suggested. If scalp hair is inaccessible, a corresponding quantity of body hair can be substituted. Head hair specifically refers to scalp hair, while body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The laboratory analysis of drug test results encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the preliminary processing of a sample within the laboratory's system. This stage ensures proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry absent from an electronic chain of custody system.

Screening offers an initial rapid assessment for substances of abuse. While cost-effective for excluding drug presence in most samples, a preliminary positive requires confirmation for legal admissibility. Samples indicating a presumptive positive during Screening demand subsequent confirmation.

During Extraction, more hair is drawn from the original sample if a presumptive positive emerges in Screening. This stage extracts substances from hair at much lower concentrations than other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug assessments.

Confirmation of any positive screening outcome employs GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Prior to confirmation, all presumptive positive samples undergo requisite washing. The comprehensive laboratory procedure from Accessioning to Confirmation is examined both under the CAP (College of American Pathologists) Hair designation and the accreditation aligned with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Sustained detection period: Hair drug assessments can identify substance use for as long as 90 days, surpassing the shorter detection span of urine tests.
• Resistance to tampering: Hair drug testing is resistant to manipulation, ensuring accuracy in results.
• Reveals usage patterns: It showcases substance consumption trends over extended durations, rather than immediate use.

Limitations:

• Inability to detect recent usage: Drugs typically become detectable in hair after approximately 5-7 days.
• Expense: Hair drug evaluations usually cost more than alternative testing techniques.
• Result variability: Factors like hair color and individual growth rates can influence metabolite concentrations in hair samples.

Note: Commonly termed as "hair follicle tests", the assessment pertains to the hair strand and not the follicle situated 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.
