Hair Follicle Drug Testing - Norwood Court, MO

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol usage. Hair offers a comprehensive timeline of alcohol and drug exposure by embedding biomarkers within the strands as they grow. When clipped close to the scalp, hair can reveal a detection period of up to three months for alcohol and drugs. Hair samples are easy to collect, challenging to alter, and convenient for shipping.

A 1.5-inch segment of around 200 hair strands (roughly the width of a #2 pencil) taken from near the scalp will yield 100mg of hair, which is optimal for testing and confirmation. For EtG, additional tests, or tests exceeding 10 panels, it is suggested to use 150mg. We suggest measuring the specimen with a jeweler’s scale. If scalp hair is unavailable, a similar quantity of body hair may be used. When mentioning head hair, we refer to scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).

Overview of the Process

The four essential phases in lab processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning signifies the primary handling of a sample in a laboratory's system. This verifies that the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any unprovided data entry from an electronic chain of custody system.

Screening entails an initial rapid assessment for drugs of abuse. While Screening is a cost-efficient method to exclude drug use in most samples, any positive screen must be verified for legal admissibility. Samples presumptively positive in Screening require a secondary confirmation.

For samples that test presumptively positive at Screening, extra hair is extracted from the original specimen and readied for Extraction. Here, drugs are extracted at much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most complex method to perform.

Any positive screening result undergoes Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed prior to confirmation as necessary. The complete lab process from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Benefits of hair drug analysis:

• Extended detection period: Hair drug analysis can identify drug use up to 90 days, unlike urine tests which offer a shorter detection period.
• Difficulty to tamper: Altering a hair drug test is very challenging, making the outcomes more reliable.
• Yields historical insight: It can illustrate a pattern of drug use over time, beyond recent use alone.

Drawbacks:

• Unable to detect recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests typically cost more than other methods.
• Inconsistencies in findings: Elements like hair color and personal hair growth differences can influence drug metabolite concentration in hair.

Note: Although termed "hair follicle tests", the analysis involves 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.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.

Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.

The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.
