Hair Follicle Drug Testing - Vanderbilt, MI

What it is, How it works

Analyzing hair has gained recognition as an effective technique for uncovering the consumption of drugs and alcohol. Hair captures a comprehensive record of alcohol and drug intake by embedding biomarkers within the hair's composition as it grows. When sourced near the scalp, hair can offer a detection span of roughly three months for alcohol and other substances. Gathering hair samples is straightforward, relatively tough to tamper with, and convenient to transport.

A 1.5-inch section consisting of approximately 200 hair strands (comparable to a #2 pencil's thickness) closest to the scalp will equate to 100mg of hair, which is optimal for initial screening and verification. For EtG enhancements and/or tests beyond 10 panels, 150mg of sample is advisable. The specimen should be weighed using a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair can be collected. Within hair testing, "head hair" pertains solely to scalp hair, whereas "body hair" includes all other forms (such as facial and axillary hair).

Process Overview

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

Accessioning refers to the initial intake of a sample into the lab’s system. This process verifies that the sample is correctly sealed and sent, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes any remaining data input not covered by an electronic chain of custody.

Screening conducts a preliminary examination for drugs. Screening serves as a cost-effective measure to dismiss drug consumption in most samples; however, a positive screening outcome must undergo confirmation to be deemed credible in court. Any samples with an initial positive screen require additional verification.

When a sample tests positive during Screening, supplementary hair is extracted from the initial batch and prepped for Extraction. This phase involves retrieving drugs from hair at significantly lower concentrations than in other testing methods (such as urine or oral fluids), highlighting why hair testing is the most challenging to execute.

Confirmation of any positive screening results is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All initially positive samples undergo requisite washing before confirmation. The complete lab process from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug analyses can detect drug consumption up to 90 days, unlike urine tests which present a shorter detection window.
• Challenging to deceive: Hair drug tests are notoriously difficult to manipulate, lending greater accuracy to the outcomes.
• Offers historical insight: This test provides a timeline of drug use rather than merely reflecting recent usage.

Limitations:

• Incapable of detecting recent usage: Drugs require about 5-7 days to manifest in hair tests.
• Expense: Typically, hair drug tests incur higher costs compared to other testing methods.
• Result variations: Influences like hair color and individual hair growth can modify the drug metabolite concentrations within the hair.

Note: Hair drug testing is often called "hair follicle tests", but it evaluates the hair shaft, not the follicle situated beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Vanderbilt, MI is superior to urine tests owing to better detection accuracy. While urine tests are limited to short-term detection, hair tests offer a comprehensive analysis of drug history, ensuring consistent reliability in substance use assessments.

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.
