Eosinophil Cationic Protein (ECP) details

What Eosinophil Cationic Protein (ECP) shows

Eosinophil cationic protein (ECP) is a protein stored inside eosinophils, a type of white blood cell involved in allergic reactions and defense against parasites. When eosinophils are activated, they release ECP, so its level in serum gives an indirect picture of how active eosinophil-driven inflammation is. It is most often used in allergic conditions such as asthma, and sometimes to follow how inflammation changes over time. A higher result can point to active eosinophilic inflammation, while a lower result suggests less activity. ECP is not specific to any one condition and does not diagnose allergy or asthma on its own, so it is interpreted alongside your symptoms, eosinophil counts and other tests.
