Hair Follicle Drug Testing - Cape Vincent, NY

What it is, How it works

Hair testing has increasingly been recognized as an effective method for detecting drug and alcohol consumption. By capturing biomarkers within the fibers of a developing hair strand, hair offers an extended history of alcohol and drug presence. When collected near the scalp, hair can reveal substance use within an approximate 3-month period. Hair is easy to gather, somewhat resistant to tampering, and simple to transport.

A 1.5-inch sample of roughly 200 hair strands (comparable in size to a #2 pencil) clipped close to the scalp yields 100mg of hair, considered the optimal quantity for analysis and validation. For EtG, additional tests, or those exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler's scale to measure the specimen's weight. If scalp hair is not present, an equivalent quantity of body hair may be substituted. In our context, head hair strictly refers to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The four primary stages in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a laboratory’s database. This includes ensuring the sample was appropriately sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data entry absent in an electronic chain of custody system.

Screening serves as an initial rapid assessment for signs of drug abuse. Though Screening is a budget-friendly approach to discount drug use in most samples, a positive result requires confirmation to be legally valid. Any samples tentatively positive in Screening necessitate a secondary affirmation.

When a sample is tentatively positive in the Screening phase, more hair is extracted from the original sample and readied for Extraction. Here, drugs are isolated from hair at a much lower concentration than in alternative methods (e.g., urine or oral fluid), which makes hair drug testing the most challenging technique to execute.

Verification of any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All tentatively positive samples are cleansed prior to confirmation as needed. The full laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair accreditation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests that have a reduced detection window.
• Difficulty to cheat: Manipulating a hair drug test is highly challenging, resulting in more precise outcomes.
• Provides historical data: It offers a timeline of drug consumption over an extended period, not merely recent use.

Limitations:

• Cannot detect recent use: Drugs typically require about 5-7 days to become detectable in hair.
• Cost: Compared to other drug testing techniques, hair drug tests are often pricier.
• Variations in results: Elements such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although often termed "hair follicle tests", the examination itself evaluates the hair strand and 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.
