| Meaning | Neutrophils are one of the primary types of white blood cells, that evokes the immune response against any foreign particle attack in the body. | Eosinophils are another type of white blood cells, that helps in fighting against disease and allergies. | Basophils are such white blood cells that help to diagnose the specific health problems like autoimmune disease or other blood disorder, etc. in the body. |
| Nucleus shape | Two-lobed nucleus. | Bean-shaped nucleus. | Multi-lobed nucleus. |
| Lifespan | The neutrophils lifespan is 5-90 hours. | The eosinophils lifespan is 8-12 hours. | The basophils have a life span of 60-70 hours. |
| Diameter | The neutrophils have a diameter of 8.85 micrometres. | The eosinophils have a diameter of 12-17 micrometres. | The basophils have a diameter of 10-14 micrometres. |
| Colour while staining | Natural pink in colour. | Brick-red in acidic stains. | Dark blue in basic stains. |
| Presence in the blood cells | Neutrophils mark up to 40-75% of the total white blood cells. | Eosinophils mark up to 1-6% of the total white blood cells. | Basophils mark up to 0.5-1% of the total white blood cells. |
| Normal Range or count | Neutrophils – 2500-8000 per mm3. | Up to 0-500 per cubic millimetres (mm3) is considered as the normal range. | Up to 0-300 per cubic millimetres (mm3) is the normal range. |
| Disease | High level leads to neutrophilia and leukocytosis, while low level of neutrophils leads to neutropenia and leukopenia. | The higher level of eosinophils leads to eosinophilia. | If the level of the basophils increases, it may lead to hypothyroidism, myeloproliferative disorders, or autoimmune inflammation. |
| Role | Neutrophils vital role is in engulfing the foreign or toxic particles through phagocytosis. | Eosinophils are the first one in triggering the inflammatory response during allergic disorders. | Basophils prevent the immediate blood clotting, as it contains heparin (anticoagulant). |
