ECP is a protein released when eosinophils degranulate (explode). This happens during allergic reactions or during some immune responses to parasites. Since Babesia is a parasite, it is reasonable to assume the body sends eosinophils to attack the Babesia. And I know there is at least one case report about a person with Hyper-Eosinophilic Syndrome who was also diagnosed with Babesiosis. So it is possible that ECP levels can be used to give a rough indication of disease activity (more accurately, immune activity against the parasite).
Testing ECP levels in the 3 specific situations may show different levels of ECP in a certain pattern if one has Babesia...I am guessing here, though and don't really know for sure.
