Eosinofiilimäärien

Eosinofiilimäärien refers to the measurement or count of eosinophils in the blood or other bodily tissues. Eosinophils are a type of white blood cell that plays a role in the immune system, particularly in fighting off parasitic infections and in mediating allergic reactions. An elevated eosinophil count, known as eosinophilia, can be indicative of various medical conditions.

Common causes of eosinophilia include allergic diseases such as asthma, hay fever, and eczema. Parasitic infections are also a frequent cause, as eosinophils are a key defense mechanism against these organisms. Certain autoimmune diseases, some types of cancer, and reactions to specific medications can also lead to increased eosinophil levels. Less commonly, eosinophilia can be associated with more severe conditions like eosinophilic granulomatosis with polyangiitis (formerly Churg-Strauss syndrome) or eosinophilic esophagitis.

The interpretation of eosinophil counts is always done in the context of a patient's overall clinical picture, including their symptoms, medical history, and results from other diagnostic tests. A low eosinophil count, known as eosinopenia, is less common and generally not considered clinically significant unless it is extremely low, which might occur during acute stress responses or corticosteroid therapy. Doctors may order a complete blood count (CBC) with differential to determine the eosinophil count.
