Hair Follicle Drug Testing - Pondsville, MD

What it is, How it works

Hair analysis is now regarded as an influential method for detecting drug and alcohol consumption. Hair captures a prolonged record of alcohol and other substances by embedding biomarkers in the strands of the growing hair. When obtained from close to the scalp, it can offer a detection window for alcohol and other substances extending up to about 3 months. Hair collection is straightforward, relatively resistant to alteration, and simple to transport.

A 1.5-inch section of roughly 200 hair fibers (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample size for screening and confirmation procedures. For EtG, supplemental tests, and/or those beyond 10 panels, a specimen of 150mg is advised. We suggest evaluating the specimen on a jeweler’s scale. Should scalp hair be absent, a proportional quantity of body hair is permissible. By head hair, we mean scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The four critical phases in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial handling of a specimen into a lab’s records. This stage includes ensuring the sample was properly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and completing any outstanding data input not supplied by an electronic chain of custody framework.

Screening denotes an immediate, preliminary examination for drugs of abuse. While Screening offers a budget-friendly means to eliminate drug involvement for most samples, a positive result necessitates confirmation for courtroom reliability. Samples suggesting positivity in Screening require subsequent verification.

If a sample suggests positivity during Screening, additional hair is extracted from the original specimen and prepared for Extraction. In Extraction, drugs are retrieved from hair at significantly diminished concentrations compared to other techniques (e.g., urine or oral fluid), signifying hair drug analysis as one of the most challenging techniques to execute.

Validation of any positive screening result is implemented via GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating positive results undergo washing before confirmation if necessary. The complete laboratory workflow from Accessioning to Confirmation undergoes examination per both the CAP (College of American Pathologists) Hair categorization and conformity to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug testing can reveal drug utilization extending up to 90 days, in contrast to urine testing, which has a shorter detection window.
• Hard to evade: Cheating a hair drug test is highly challenging, ensuring accuracy in the results.
• Yields historical insight: It can depict a timeline of drug utilization over several months, not merely recent usage.

Limitations:

• Cannot identify recent intake: Drugs require about 5-7 days to be observable in hair.
• Expense: Generally, hair drug testing incurs higher costs than alternative drug testing methods.
• Inconsistencies in findings: Variables such as hair color and personal differences in hair growth can influence drug metabolite concentration within the hair.

Note: Though often termed "hair follicle tests", the analysis focuses on the hair strand rather than 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.
