Platelet Count by Phase Contrast Microscopy –- New Diluting Fluid for Better Visualization

Abstract

A new diluting fluid is recommended for chamber counting of platelets. This diluting fluid makes the core of the platelets appear jet black and very distinct with phase contrast microscopy. The leucocytes are also well preserved and may easily be counted, whereas the erythrocytes are hemolyzed.

Key Words:

• Diluting fluid
• platelet count
• phase contrast microscopy
