Hair Follicle Drug Testing - Laurel, MD

What it is, How it works

Hair analysis has gained recognition as an effective method for detecting drug and alcohol consumption. Hair acts as a historical record of substance use by embedding biomarkers within the hair strand's fibers. When collected near the scalp, hair offers a detection span of up to 90 days for drugs and alcohol. It's easy to collect, less susceptible to tampering, and simple to transport.

A 1.5-inch sample of around 200 hairs (comparable to the thickness of a #2 pencil) from the scalp yields 100mg, optimal for screening and confirmation. For EtG, extras, and/or panels above 10, 150mg is advised. We suggest using a jeweler’s scale for weighing. If scalp hair isn't available, an equivalent amount of body hair can be gathered. Head hair specifically refers to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning serves as the initial introduction of a sample into the lab's system. This step ensures the sample was sealed and transported correctly, assigns a unique LAN (Laboratory Accessioning Number), and addresses any data entry omissions from electronic chain of custody systems.

Screening is a preliminary rapid check for substance abuse. Though it’s a cost-effective way to discard drug use in most samples, a positive screen needs confirmation for courtroom acceptability. Any samples that test presumptively positive in Screening require further confirmation.

Upon a presumptive positive result in Screening, additional hair is extracted from the original sample and prepped for Extraction. During this phase, drugs are extracted from hair at concentrations lower than those in other methods (like urine or oral fluid), emphasizing the complexity of hair drug testing.

Confirmation of a positive screen is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are cleaned prior to confirmation if necessary. The complete process from Accessioning to Confirmation is overseen according to both CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use up to 90 days, unlike urine tests which offer a shorter window.
• Difficult to evade: The test's resistance to cheating enhances result accuracy.
• Provides usage patterns: It offers an overview of drug use trends over time, rather than just recent activity.

Limitations:

• Unable to detect recent activity: Detection in hair takes around 5-7 days post-use.
• Expense: Hair drug testing usually costs more than other methods.
• Result variability: Hair color and growth differences can influence drug metabolite concentrations in hair.

Note: Often called "hair follicle tests," they assess 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. 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.
