Hair Follicle Drug Testing - Belmont, PA

What it is, How it works

Hair testing is now recognized as a potent method for identifying drug and alcohol usage. It provides a comprehensive history of substance use by embedding biomarkers in the hair strand fibers as they grow. When taken near the scalp, hair offers a potential detection period of up to about 90 days for alcohol and other substances. It is easy to gather, hard to tamper with, and straightforward to transport.

A 1.5-inch segment of approximately 200 strands of scalp hair (roughly the width of a #2 pencil) yields 100mg, which is the optimal amount for analysis and validation. For EtG, add-ons, or tests beyond 10 panels, 150mg of sample is suggested. It is advised to weigh the sample on a jeweler’s scale. If head hair is not available, an equivalent amount of body hair might be used. Head hair pertains strictly to scalp hair, while body hair includes all other types (facial, axillary, etc.).

Process Overview

The four primary steps in the laboratory handling of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the sample's initial processing in a lab's system, which involves confirming the sample was sealed and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and completing extra data entry absent from an electronic custody chain system.

Screening entails an initial rapid assessment for substance misuse. Although it is an affordable method to exclude drug use in most samples, a positive screen must be verified for legal acceptability. Presumptive positives in Screening demand further confirmation.

If a sample tests presumptive positive during Screening, additional hair is extracted from the original sample for the Extraction stage. Here, substances are derived from hair at much lower concentrations compared to other methods (like urine or oral fluid), which makes hair drug detection the most challenging method to execute.

Confirming any positive screen result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleaned before confirmation as necessary. The complete lab process from Accessioning to Confirmation is evaluated according to both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection window: Detects drug use for up to 3 months, unlike the shorter detection period of urine tests.
• Hard to manipulate: Cheating on a hair drug test is challenging, allowing for more precise results.
• Provides usage history: Offers a usage pattern of drugs over time, not just recent use.

Limitations:

• Cannot detect recent usage: It takes around 5-7 days for drugs to show up in hair.
• Costly: Typically, hair drug tests cost more compared to other methods.
• Result variability: Factors like hair color and individual hair growth differences can alter drug metabolite levels in hair.

Note: Though often termed "hair follicle tests", the analysis concerns 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.
