White blood cells containing granules and lobed nuclei are classified as

agranulocytes

granulocytes

thrombocytes

megakaryocytes

Granulocytes are a type of white blood cell characterized by their granular cytoplasm and lobed nuclei. They play key roles in the immune response, helping to fight off infections and responding to inflammation. The three main types of granulocytes are neutrophils, eosinophils, and basophils, each specialized for different pathogen types or immune functions.

In real-world application, granulocytes are essential in diagnosing various medical conditions. For instance, an elevated neutrophil count can indicate bacterial infections, while increased eosinophils can signal allergic reactions or parasitic infections. Doctors often analyze a complete blood count (CBC) to assess the proportion of these cells to understand a patient’s health better.
