Hair Follicle Drug Testing - Berwyn Heights, MD

What it is, How it works

Hair testing is increasingly recognized as an effective approach for identifying drug and alcohol consumption. By encapsulating biomarkers within the fibers of the hair as it grows, hair offers a comprehensive history of substance use. When taken near the scalp, a sample can reveal drug and alcohol use for nearly three months. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil's thickness) nearest to the scalp yields about 100mg — an optimal amount for evaluation and verification. To test for EtG, additional substances, or more than 10 panels, 150mg of hair is advisable. It's suggested to measure the hair on a jeweler’s scale. If scalp hair is not accessible, a similar quantity of body hair may be used. When mentioning head hair, we refer only to scalp hair. Body hair encompasses all other hair varieties (such as facial or axillary hair).

Process Overview

The laboratory handling of a drug test result is comprised of four crucial phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase, where the sample is integrated into a lab's system. This step ensures the sample's seal and shipment are intact, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry that the electronic chain of custody does not cover.

Screening performs an initial basic assessment for illegal substances. Though Screening offers an economical means to discard drug usage in the majority of samples, a positive result must be confirmed for judicial acceptance. Any samples deemed as potentially positive during Screening need further verification.

If a sample shows a possible positive during Screening, additional hair is taken from the original sample and readied for Extraction. In this phase, much lower drug concentrations are drawn from the hair compared to other methods (such as urine or saliva), which makes hair drug testing the most demanding method to execute.

Positive screening findings undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity are washed before confirmation, if necessary. The entire procedure, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug consumption for up to 90 days, unlike urine tests, which cover a shorter timeframe.
• Hard to tamper: It's nearly impossible to deceive a hair drug test, ensuring higher accuracy.
• Delivers historical insight: It shows drug use patterns over time, not merely recent activity.

Limitations:

• Unable to detect recent use: It typically takes 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug testing tends to be pricier than other methods.
• Result variability: Elements like hair color and unique growth rates can impact the drug metabolite levels in hair.

Note: Frequently called "hair follicle tests", the examination actually analyzes 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.
