A proper understanding of setting up and using your microscope is essential for obtaining reliable, high-quality diagnostic results. This ensures optimal illumination, focus, and contrast, to ensure you are able to examine samples easily. Diff-Quik staining provides rapid, clear visualisation of cells and micro-organisms, but only when applied correctly. Knowing how to systematically analyse samples helps you recognise artefacts, identify key structures, and avoid misinterpretation. Together, these skills form the foundation of accurate, confident microscopic examination and will be covered in this section.
