Hair Follicle Drug Testing - Medford, MA

What it is, How it works

Hair assessments have emerged as an effective means for identifying alcohol and drug consumption. Hair retains a prolonged record of substances by embedding biomarkers in the fibers of the developing hair shaft. When gathered near the scalp, hair can offer roughly a 3-month timeframe to detect alcohol and drugs. Hair is straightforward to collect, somewhat challenging to tamper with, and easy to dispatch.

A 1.5-inch segment comprising approximately 200 hair strands (comparable in size to a #2 pencil) closest to the scalp yields 100mg of hair, the optimal quantity for analysis and validation. For EtG, accessories, and/or tests exceeding 10 panels, a 150mg sample is advisable. We suggest using a jeweler’s scale for weighing the sample. If scalp hair is inaccessible, an equivalent amount of body hair can be sourced. When referencing head hair, it pertains solely to scalp hair. Body hair denotes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary integration of a sample into a laboratory's framework. This process includes ensuring the sample was appropriately sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and executing any supplementary data entry not covered by an electronic chain of custody process.

Screening entails an initial rapid assessment for drugs of concern. Although Screening is a cost-efficient method to exclude drug usage for the majority of samples, a positive screen necessitates confirmation for legal admissibility. Any samples preliminarily positive in Screening must undergo secondary verification.

Should a sample appear preliminarily positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are isolated from hair at markedly lower concentrations than other techniques (such as urine or oral fluid), rendering hair drug screening the most complex method to execute.

GC/MS, GC/MS/MS, or LC/MS/MS methods are employed to confirm any positive screen outcome. All samples deemed preliminarily positive undergo washing before confirmation as required. The entire laboratory process, from Accessioning through Confirmation, is reviewed under the CAP (College of American Pathologists) Hair designation alongside ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can trace drug use for up to 90 days, unlike urine tests which feature a shorter detection span.
• Difficulty to cheat: Hair drug tests are notoriously difficult to manipulate, ensuring more accurate outcomes.
• Provides historical data: It can delineate a drug usage pattern over time, beyond just recent consumption.

Limitations:

• Cannot detect recent use: Detections in hair require approximately 5-7 days post-use.
• Cost: Hair drug tests typically incur higher costs than alternative methodologies.
• Variations in results: Factors such as hair color and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: While sometimes termed as "hair follicle tests," the analysis itself examines the hair strand, not the follicle located 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.
