Hair Follicle Drug Testing - Greenland, MI

What it is, How it works

Hair examinations have become recognized as an effective means for detecting drug and alcohol consumption. Hair can offer extensive historical insights into substances by capturing biomarkers within the fibers of the hair as it grows. When collected near the scalp, it can allow for a detection window of almost three months for substances. Hair collection is straightforward, challenging to falsify, and simple to transport.

A sample of 1.5 inches in length consisting of around 200 hair strands (approximately the diameter of a #2 pencil) nearest the scalp will provide 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, and/or panels greater than 10, 150mg of hair is advisable. It is suggested to weigh the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent amount of body hair may be used. "Head hair" specifically refers to scalp hair, whereas "body hair" includes all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning pertains to the initial intake of a sample into the laboratory's system. This process involves ensuring the sample was sealed and dispatched correctly, generating a LAN (Laboratory Accessioning Number) at random, and completing any extra data entry not managed by an electronic chain of custody system.

The Screening step is a preliminary check for substance abuse. While Screening is cost-effective for eliminating drug usage in most samples, a positive result requires confirmation for court acceptance. Samples presumed positive in the Screening phase mandate further confirmation.

If a sample is suspected positive during Screening, additional hair is extracted from the original sample and readied for Extraction. In this phase, substances are removed from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug tests the most complex to execute.

Positive screening confirmations are undertaken using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing before confirmation as dictated. The complete laboratory process from Accessioning to Confirmation adheres to the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests reveal drug usage up to 90 days, unlike urine tests, which have a more limited detection span.
• Challenging to manipulate: Cheating a hair drug test is notably difficult, ensuring more reliable results.
• Reveals past usage trends: It can indicate drug consumption over time, not just recent intake.

Limitations:

• Incapable of identifying recent intake: Drugs require around 5-7 days to be traceable in hair.
• Expense: Hair drug tests typically incur higher costs than other drug testing approaches.
• Result variability: Aspects like hair color and individual hair growth variations can influence the concentration of drug metabolites in hair.

Note: Although sometimes 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.
