Hair Follicle Drug Testing - San Castle, FL

What it is, How it works

Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of alcohol and drug intake by embedding biomarkers within the fibers of the hair shaft as it grows. When taken near the scalp, hair can offer approximately a 90-day detection period for substances. Hair is easy to collect, hard to tamper with, and simple to transport.

A strand cluster of 1.5 inches, roughly 200 strands (comparable to the width of a #2 pencil) closest to the scalp, provides 100mg of hair, ideal for initial testing and further confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of hair is preferred. Using a jeweler’s scale for weighing the sample is advisable. If scalp hair is not available, the equivalent amount of body hair may be used. When discussing head hair, we refer specifically to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The drug testing laboratory process consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase of entering a sample into the laboratory’s system. This phase confirms that the sample was securely sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry absent in an electronic chain of custody system.

Screening is a preliminary rapid assessment for the presence of drugs. Though Screening offers an economical way to negate drug use in most samples, results that yield positive screens need validation for court admissibility. Samples showing a presumptive positive in Screening demand a follow-up confirmation.

If a sample tests presumptively positive during the Screening, additional hair is taken from the original sample for the Extraction phase. Here, drugs are isolated from hair at significantly lower concentrations compared with alternative methods (e.g., urine or oral fluid), making hair drug screening a particularly challenging method.

Confirmation of any preliminary positive screen is executed using GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples undergo washing before confirmation where necessary. From Accessioning to Confirmation, the entire lab process is evaluated under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can identify drug consumption for up to 90 days, unlike urine tests which offer a shorter timeframe.
• High accuracy: Tampering with a hair drug test is notably difficult, enhancing the reliability of results.
• Chronological usage data: It reveals drug usage patterns over a period, not merely recent consumption.

Limitations:

• Lacks immediate detection: Drugs require about 5-7 days before becoming traceable in hair.
• Expense: Hair drug testing costs generally surpass those of other testing methods.
• Result variability: Individual differences in hair color and growth can influence drug metabolite concentrations in hair.

Note: Commonly termed as "hair follicle tests", the analysis focuses on the hair strand itself, not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

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.
