Hair Follicle Drug Testing - Saint Paul, IA

What it is, How it works

Hair analysis is recognized as an effective mechanism for identifying drug and alcohol consumption. Hair records long-term substance use by embedding biomarkers within its fibers as it grows. When collected near the scalp, it offers roughly a 3-month detection period for alcohol and drugs. Hair collection is straightforward, challenging to alter, and convenient for shipping.

To obtain an effective sample for analysis, a 1.5-inch portion of around 200 hair strands (approximately the diameter of a #2 pencil) closest to the scalp is ideal, providing 100mg of hair. For EtG add-ons or tests beyond 10 panels, 150mg is preferred. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair isn’t available, a similar amount of body hair can be utilized. "Head hair" refers specifically to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

The drug testing laboratory process comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed into the lab's system. This step ensures the sample was sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any required data entry not covered by an electronic chain of custody.

Screening is a preliminary, quick evaluation for drugs of abuse. It’s a cost-effective method to identify negative samples, but any positive screen requires confirmation to be legally valid. Samples testing positive in Screening need further confirmation.

For those testing positive in Screening, additional hair is extracted and prepared for Extraction. This process extracts drugs from hair in much lower concentrations than other methods (e.g., urine, oral fluid), marking hair drug screening as particularly complex.

Confirmation involves using GC/MS, GC/MS/MS, or LC/MS/MS for any samples flagged as positive. Any presumptive positive samples undergo washing before Confirmation as necessary. The entire lab process, from Accessioning to Confirmation, is scrutinized under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug use up to 90 days, in contrast to urine tests which have shorter detection capabilities.
• Hard to manipulate: Cheating a hair drug test is very challenging, ensuring more reliable results.
• Provides use history: It illustrates a drug use pattern over time, not just recent intake.

Limitations:

• Inability to detect recent use: Drugs become traceable in hair after approximately 5-7 days.
• Expense: Hair drug tests tend to be more costly than other testing methods.
• Result variability: Variables like hair color and individual hair growth differences can influence drug metabolite levels in hair.

Note: This test, often misnamed as "hair follicle tests", actually examines the hair strand rather than 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.
