Hair Follicle Drug Testing - Casnovia, MI

What it is, How it works

Hair testing is recognized as a significant method for identifying drug and alcohol usage. Hair captures a prolonged record of alcohol and drug consumption by embedding biomarkers in the strands of the hair as it grows. When gleaned near the scalp, hair can offer a detection range of up to around 3 months for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and effortlessly shippable.

A sample measuring 1.5 inches from approximately 200 hair strands (equivalent to a #2 pencil's thickness) adjacent to the scalp will yield 100mg of hair, which is the optimum sample size for testing and corroboration. For EtG, additional analysis, and/or panels exceeding 10, a sample of 150mg is advisable. It is suggested to use a jeweler’s scale to weigh the sample. Should scalp hair be unavailable, a proportionate quantity of body hair can be used. The term head hair pertains solely to scalp hair, while body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The key stages in the laboratory process for drug test outcomes involve Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, the sample undergoes initial processing into the lab's system. This step confirms proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and concludes any extra data entries absent from an electronic chain of custody system.

Screening is a preliminary rapid check for drug abuse. While cost-efficient for eliminating drug use in most samples, a positive screen must be confirmed to be court-valid. Any presumptively positive samples from Screening necessitate additional confirmation.

Should a sample be presumptively positive during Screening, more hair is extracted from the initial collection and prepped for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations compared to other methods (ex. urine or oral fluid), making hair drug testing especially challenging.

GC/MS, GC/MS/MS, or LC/MS/MS approaches confirm any positive screen results. All presumptive positive samples undergo pre-confirmation washing if needed. From Accessioning to Confirmation, the lab process adheres to both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, as opposed to urine tests with shorter detection periods.
• Hard to falsify: Cheating a hair drug test is extremely difficult, contributing to more precise outcomes.
• Offers longitudinal data: It can reflect a trend of drug use over time, rather than just recent consumption.

Limitations:

• Inability to detect immediate use: Drugs become discernible in hair in roughly 5-7 days.
• Expense: Hair drug tests tend to cost more than alternative testing methods.
• Result variability: Variances like hair color and personal hair growth differences can impact drug metabolite concentrations in the hair.

Note: Though commonly called "hair follicle tests," the analysis actually examines the hair strand and 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.
