Using your right hand, place the smooth, clean edge of a retractor on the specimen slide in front of the blood drop.4. The dispensing glass is held at 30° and the drop of blood is aspirated5. The blood has spread almost to the edges6. The spread is pushed forward in a light, smooth, fluid motion. A bullet- or tongue-shaped strand of blood with a feathered edge will remain on the slide.7. The frosted edge is labeled with the patient's name, ID and date.8. Allow the blood smear to dry completely before staining.Preparation of a thin blood smear: 1. A small drop of venous blood is placed on a microscope slide, using a disposable pipette. For this purpose, a wooden applicator stick2 was used. A distribution glass is placed obliquely and slowly dragged towards the blood drop.3. Bring the spacer glass into contact with the drop of blood and remove it. The edge of the spreader slide is noted.4. The distribution slide is further pulled out forming a thin layer of blood.5. The blood smear is almost complete6. Result finished. A slide with a well-formed layer of blood. After drying for approximately 10 minutes, the slide is stained manually or an automatic slide stain is placed. Coloring
