Leishman's stain, RBC fluid and WBC fluid

Leishman's stain, RBC fluid and WBC fluid: Leishman's stain, a type of Romanowsky stain used in hematology to differentiate and identify blood cells, including red blood cells (RBCs) and white blood cells (WBCs). Leishman's stain is a mixture of methylene blue and eosin, which stains RBCs pink or red and WBCs blue or purple, allowing for easy identification and counting under a microscope. Hayem's fluid is a diluting fluid used in hematology to count red blood cells (RBCs). It's a mixture of mercuric chloride, sodium sulfate, sodium chloride, and distilled water. The composition of Hayem's fluid is: 1. Mercuric chloride (0.25 g) 2. Sodium sulfate (2.5 g) 3. Sodium chloride (0.5 g) 4. Distilled water (100 mL) Hayem's fluid helps preserve RBCs, prevents clotting, and provides a suitable medium for counting RBCs under a microscope. Turk's fluid is a diluting fluid used in hematology to count white blood cells (WBCs). It's a mixture of glacial acetic acid, gentian violet, and distilled water. The composition of Turk's fluid is: 1. Glacial acetic acid (1-2 mL) 2. Gentian violet (1% aqueous solution, 1 mL) 3. Distilled water (100 mL) Turk's fluid helps lyse red blood cells, stain WBC nuclei, and provide a suitable medium for counting WBCs under a microscope.
