What is amebiasis?
An eosinophil is a type of white blood cell that plays a role in your immune system. A blood test that measures the number of eosinophils in your blood is called an "eosinophil count" or "eosinophil blood test." Eosinophils are a component of your complete blood count (CBC), which is a common blood test used to assess overall health and to diagnose and monitor a variety of medical conditions.

Eosinophils are typically reported as a percentage of the total white blood cell count or as an absolute count, which is the actual number of eosinophils per microliter of blood. Eosinophil counts can vary within a normal range, but abnormally high or low levels may indicate different health conditions.
Elevated eosinophil counts (eosinophilia) can be associated with various conditions, including allergies, asthma, parasitic infections, autoimmune diseases, and certain types of cancers. A high eosinophil count can help healthcare providers in diagnosing and monitoring these conditions.
Conversely, a low eosinophil count may be seen in certain conditions like sepsis, corticosteroid medications, or autoimmune disorders, but it is less common for low eosinophil counts to be the primary focus of medical evaluation.
Your healthcare provider will interpret your eosinophil count in the context of your overall health and medical history, as well as other test results, to determine if further investigation or treatment is necessary. If you have questions or concerns about your eosinophil count or any other aspect of your blood test results, it's best to discuss them with your healthcare provider.
The normal range for eosinophil counts can vary slightly from one laboratory to another, and it can also depend on factors like age, sex, and overall health. However, in general, a normal eosinophil count typically falls within the following ranges:
Absolute eosinophil count: Usually, the normal range is approximately 0 to 350 eosinophils per microliter (µL) of blood.
Percentage of eosinophils in the total white blood cell count: Typically, eosinophils make up about 1-6% of the total white blood cell count.
Keep in mind that the specific reference ranges used by a particular laboratory may differ, so it's essential to interpret your results in the context of the reference range provided by the lab that conducted the test.
If your eosinophil count falls outside the normal range, it can indicate the presence of an underlying medical condition or an immune response to allergens or infections. Your healthcare provider will consider your overall health and other test results to help determine the significance of your eosinophil count in your specific case.
