Question

In the process of investigation of leukogram it was determined that one of the types of leukocytes makes up less that 1 per cent. What structural features should be taken into consideration to define the type of those leukocytes?

Answer 1

The leukocytes that make up less than 1% could include basophils or eosinophils. To define the type of these leukocytes, the following features should be considered:

• the shape of the nucleus (basophils have a bean-shaped or bilobed nucleus);
• cytoplasm staining (basophils are stained in dark blue or purplish-black);
• presence of granules (basophils have large dark purple cytoplasmic granules covering the entire cytoplasm)
