Area of Science:

Biomarkers and Molecular Toxicology
Occupational Health and Safety
Genetics and Genomics

Background:

Biological effect indicators, particularly DNA damage biomarkers, are crucial for risk assessment and predicting carcinogenesis.
The micronucleus test is a common assay for DNA damage but traditionally requires invasive lymphocyte sampling.
Current limitations hinder the application of the micronucleus test in routine occupational safety monitoring.

Purpose of the Study:

To develop a rapid, non-invasive, and cost-effective method for conducting the micronucleus test.
To adapt the micronucleus test for human blood samples compatible with occupational safety procedures.

Main Methods:

Development of a novel protocol for the micronucleus test.
Utilizing immature erythrocytes (reticulocytes) from human blood smears obtained via finger prick.
Staining reticulocytes with Acridine Orange for analysis.

Main Results:

Successful adaptation of the micronucleus test for non-invasive human blood samples.
The new method allows for rapid and cost-effective assessment of DNA damage.
The protocol is compatible with occupational safety screening.

Conclusions:

The developed method offers a practical approach to biomonitoring DNA damage in occupational settings.
This non-invasive technique expands the utility of the micronucleus test for human health risk assessment.
Facilitates routine occupational safety procedures by enabling accessible genotoxicity testing.
