PUS ROUTINE MICROSCOPY Detail

Pus Routine Microscopy is a laboratory test used to examine pus samples under a microscope to determine the underlying cause of infection. Pus is a thick fluid composed of dead white blood cells, tissue debris, and microorganisms, typically collected from infected wounds, abscesses, or body cavities.

The sample is analyzed to detect:

• White blood cells (WBCs): indicating the presence and degree of inflammation.

• Red blood cells (RBCs): if present, may indicate tissue damage.

• Epithelial cells and debris: may be seen in the background.

• Bacteria, fungi, or parasites: may be seen directly or suggested by inflammatory response.

Microscopy helps in the preliminary diagnosis of bacterial infections, especially pyogenic (pus-forming) infections, and guides further tests such as Gram staining and culture and sensitivity. It is a crucial step in the assessment of localized infections and helps in the selection of appropriate antibiotic therapy.
