Hair Follicle Drug Testing - Mackinaw City, MI

What it is, How it works

Hair testing is recognized as an effective approach for identifying drug and alcohol use. Hair offers a historical record of alcohol and drug consumption by embedding biomarkers within the fibers of the growing strand. Collected near the scalp, hair can reveal up to a three-month history for alcohol and drugs. It is easy to gather, less prone to falsification, and convenient to transport.

A standard collection involves a 1.5-inch length of around 200 hair strands (roughly the thickness of a #2 pencil) from near the scalp, yielding 100mg, which is the optimal quantity for testing and verification. For tests like EtG, additional panels, or those exceeding 10 panels, 150mg of the sample is advised. Measuring the sample on a jeweler’s scale is suggested. If scalp hair is missing, a comparable amount of body hair can be used. References to head hair only pertain to scalp hair, while body hair encompasses other types (like facial or axillary hair).

Process Overview

The laboratory protocol for processing drug test samples encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the sample's initial entry into the lab system. This involves confirming the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data input not covered by an electronic chain of custody.

Screening is a preliminary, swift examination for drugs. Though a cost-efficient technique to exclude drug use for most samples, a positive screen must be validated for legal proceedings. Any Screening phase presumptive positives must undergo secondary confirmation.

For presumptive positives in Screening, additional hair is extracted from the initial sample for further preparation in Extraction. At this stage, drug extraction from hair occurs at considerably lower concentrations compared to other methods (such as urine or oral fluid), making hair drug testing the most challenging method.

Confirmation of any positive screen is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo a wash prior to confirmation when necessary. The whole process from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair criteria and aligns with the ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection window: Hair tests identify drug use for up to 90 days, unlike urine tests which offer a shorter timeframe.
• Hard to manipulate: Cheating a hair drug test is difficult, enhancing result accuracy.
• Offers historical insights: It shows a timeline of drug use over time, beyond just recent consumption.

Drawbacks:

• Lacks recent use detection: It takes about 5-7 days before drugs are detectable in hair.
• Expense: Hair drug tests usually cost more than other testing options.
• Result variance: Elements like hair color and individual growth patterns affect metabolite concentration in hair.

Note: Although commonly called "hair follicle tests", the analysis is conducted on the hair strand, 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. 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.
