Time-saving in biological dosimetry by using the automatic metaphase finder Metafer2

Area of Science:

• Cytogenetics
• Radiation Biology
• Biotechnology

Background:

• Chromosome aberration analysis is crucial for biological dosimetry.
• Traditional cytogenetic analysis is time-consuming and labor-intensive.
• Automated metaphase finding can potentially improve efficiency.

Purpose of the Study:

• To quantify the time-saving benefits of the Metafer2 metaphase finder.
• To evaluate the efficiency of automated metaphase detection in routine analysis.
• To assess the impact of automated systems on cytogenetic analysis workflows.

Main Methods:

• Human peripheral blood lymphocytes were cultured and prepared using standard cytogenetic methods.
• Slides were stained with Giemsa or the FPG method.
• The Metafer2 metaphase finder was employed for metaphase detection and automated data processing.

Main Results:

• Routine analysis of 1000 metaphases without automation requires 51.5 working hours for cytogenetic analysis.
• Using the Metafer2 metaphase finder reduced cytogenetic analysis time to 17.3 working hours (3.0x time saving).
• In prolonged analysis including karyotyping, time saving factors of 1.9 were observed.

Conclusions:

• The Metafer2 metaphase finder offers substantial time savings for routine analysis of chromosome aberrations.
• Automation significantly enhances the efficiency of biological dosimetry workflows.
• Implementing automated metaphase finders is beneficial for laboratories performing cytogenetic analysis.
