Hair Follicle Drug Testing - Miami Shores, FL

What it is, How it works

Hair screening has emerged as an effective means for identifying the consumption of substances such as drugs and alcohol. Hair captures a prolonged history of substance use, embedding biomarkers within the fibers of the hair as it grows. Sampling hair close to the scalp offers a detection timeframe of roughly three months for alcohol and drugs. Hair collection is straightforward, hard to tamper with, and convenient to transport.

A 1.5-inch segment consisting of approximately 200 hair strands (similar in size to a #2 pencil) near the scalp equates to 100mg, which is the optimal amount for analysis and validation. For EtG and other additional tests exceeding ten panels, a specimen of 150mg is preferred. Using a jeweler’s scale is advisable for specimen weighing. In the absence of scalp hair, a similar quantity of body hair can be used. "Head hair" specifically pertains to scalp hair, whereas "body hair" covers other types like facial or axillary hair.

Process Overview

The laboratory analysis process for drug testing incorporates four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a laboratory's system. This step verifies correct sealing and shipment of the sample, issues a random LAN (Laboratory Accessioning Number), and completes any necessary data entry absent from an electronic chain of custody.

Screening conducts a preliminary rapid assessment for substance abuse. Although cost-efficient for excluding drug usage in most cases, a positive screen necessitates confirmation for legal acceptance. Presumed positive samples in Screening must undergo further confirmation.

In cases of a presumed positive result during Screening, additional hair is extracted from the initial sample for Extraction. This phase extracts drugs from hair at significantly lower concentrations than other methods (e.g. urine or oral fluids), accentuating the complexity of hair drug screening.

Confirmation for any positive findings from screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positives are washed as necessary. The entire laboratory procedure, from Accessioning to Confirmation, is audited according to both the CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use spanning up to 90 days, surpassing the shorter detection span of urine tests.
• High resistance to manipulation: Cheating a hair drug test is substantially challenging, thereby ensuring greater result accuracy.
• Chronological consumption patterns: It reveals drug usage trends over time, beyond just recent consumption.

Limitations:

• Inability to detect immediate use: Drugs take around 5-7 days to become traceable in hair.
• Expense: Hair drug testing typically incurs higher costs compared to alternative drug testing techniques.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Commonly known as "hair follicle tests", the procedure actually examines 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.
