Hair Follicle Drug Testing - Littleton, MA

What it is, How it works

Hair testing is recognized as a robust method for identifying drug and alcohol use. By capturing biomarkers within the strands of growing hair, it presents a comprehensive history of drug and alcohol consumption. When obtained near the scalp, hair can reveal substance use for approximately three months. The process of collecting hair is straightforward, challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches with about 200 hair strands (roughly the thickness of a #2 pencil) nearest the scalp yields 100mg, an optimal quantity for screening and confirmation. For EtG, add-ons, and/or tests beyond 10 panels, a 150mg sample is advisable. It is recommended to use a jeweler's scale for weighing the sample. In cases where scalp hair isn't available, an equivalent volume of body hair can be utilized. "Head hair" refers specifically to scalp hair, while "body hair" pertains to all other types (facial, underarm, etc.).

Process Overview

Drug test lab processing involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step of incorporating a sample into a lab's system, involving verifying the sample's proper sealing and shipment, assigning a LAN (Laboratory Accessioning Number), and completing any data entry not provided by an electronic chain of custody system.

Screening entails a swift preliminary drug check. This initial stage can efficiently exclude drug use in most samples, yet any positive screen must be verified for legal admissibility. Presumptively positive samples require subsequent confirmation.

In cases where a sample returns a presumptive positive result during Screening, additional hair from the initial sample is collected for the Extraction process. During Extraction, drugs are separated from hair at much lower concentrations than other methods (e.g., urine or oral fluid), which is why hair drug screening is particularly challenging.

GC/MS, GC/MS/MS, or LC/MS/MS techniques confirm any positive screening outcomes. All presumptive positives undergo washing before confirmation as necessary. The lab process from Accessioning to Confirmation is thoroughly vetted under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair tests reveal drug use for up to 90 days, unlike urine tests with shorter detection times.
• Difficult to cheat: Hair tests are hard to manipulate, ensuring accurate results.
• Historical use data: These tests outline drug usage patterns over time, not just recent consumption.

Limitations:

• Incapable of detecting recent use: Drugs take 5-7 days to appear in hair samples.
• Expense: Hair tests generally cost more than other methods.
• Result variations: Hair color and individual growth rates can alter drug metabolite concentrations in hair.

Note: Although often termed "hair follicle tests," the analysis focuses on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Littleton, MA, hair follicle testing surpasses urine testing by offering superior accuracy and reliability. Compared to urine tests, hair tests provide a broader detection window, capturing a longer period of drug history. This grants enhanced accuracy, significantly reducing false results.

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.
