Question: 1 / 400

After spreading a drop of blood across a glass slide, what is the next step?

Allow it to air dry

Allowing the blood smear to air dry is crucial for the preparation of a good specimen. When a drop of blood is spread across a glass slide, it forms a thin film that needs to dry completely before any further processing. Air drying prevents the cells from being distorted and ensures that they remain in their natural shape for microscopic examination.

Once dried, the slide can then be treated for staining or preserved, depending on the protocols you are following. This drying step is essential for maintaining the integrity of the cells and preventing unnecessary damage that can occur if other steps, such as staining or heating, are attempted while the sample is still wet.
