Eosinofiilimäärä

Eosinofiilimäärä refers to the count of eosinophils in a blood sample. Eosinophils are a type of white blood cell, also known as granulocytes, that play a role in the immune system. They are particularly involved in fighting parasitic infections and modulating allergic inflammatory responses. An eosinophil count is typically measured as part of a complete blood count (CBC) with differential. This test provides information about the different types of white blood cells present in the blood.

Elevated eosinophil counts, known as eosinophilia, can indicate various conditions. Common causes include allergic reactions such as asthma, hay fever, and eczema. Parasitic infections are another significant cause of eosinophilia. Certain autoimmune diseases, inflammatory conditions, and some types of cancer can also lead to an increased number of eosinophils. Less commonly, eosinophilia can be a side effect of certain medications.

A low eosinophil count, or eosinopenia, is generally less clinically significant than eosinophilia. It can be associated with the body's response to stress, such as during surgery or after administration of certain steroids. The normal range for eosinophils in the blood can vary slightly between laboratories, but typically it is a small percentage of the total white blood cell count. Doctors use the eosinophil count in conjunction with other clinical findings and test results to diagnose and manage a patient's condition.
