Hair Follicle Drug Testing - Pine Hills, FL

What it is, How it works

Hair examinations have emerged as an influential method for identifying drug and alcohol consumption. It offers a prolonged history of substance use by embedding biomarkers within the fibers of hair as it grows. When sampled near the scalp, hair offers a detection timeframe of up to around 3 months for alcohol and drugs. It's easy to gather, relatively challenging to tamper with, and straightforward to transport.

A 1.5-inch segment consisting of roughly 200 hair strands (about the girth of a #2 pencil) proximal to the scalp yields 100mg of hair, which is the optimal quantity for analysis and verification. For EtG, add-ons, or tests beyond 10 panels, a 150mg sample is suggested. It’s advisable to measure the sample using a jeweler’s scale. If scalp hair isn't available, a comparable quantity of body hair is acceptable. References to head hair imply scalp hair exclusively. Body hair incorporates other types (facial, axillary, etc.).

Process Overview

The lab processing of a drug test result comprises four major stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with the initial setup of a sample into the lab’s system. It involves confirming the sample is sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry that isn't covered by an electronic chain of custody system.

Screening is the initial rapid assessment for signs of drug abuse. While cost-efficient for negating drug usage in most samples, a positive screen necessitates confirmation for court acceptance. Samples presumptively positive in Screening need additional confirmation.

If a sample is deemed presumptively positive during Screening, further hair is extracted from the original sample and prepared for Extraction. At this stage, drugs are retrieved from hair at significantly lower concentrations compared to other techniques (such as urine or oral fluid), making hair drug analysis the most complex technique to conduct.

Confirmation of any positive Screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as needed. The complete lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug checks can identify drug use for up to 90 days, whereas urine tests detect for a shorter period.
• Hard to falsify: Cheating on a hair drug test is notably difficult, enhancing the credibility of the results.
• Offers historical data: These tests reveal a pattern of substance use over time, not just recent usage.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair around 5-7 days post-consumption.
• Expense: Hair drug testing usually incurs higher costs compared to other testing methods.
• Results variability: Factors such as hair color and individual discrepancies in hair growth might influence the concentration of drug metabolites in hair.

Note: Although commonly called "hair follicle tests," the test evaluates the hair strand and not the hair follicle under 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.
