A serologic test can be used as an adjunct in the diagnosis of babesiosis or in seroepidemiologic surveys of the prevalence of the infection in certain populations. Babesiosis is usually diagnosed by observing the organisms in infected RBCs on Giemsa-stained thin blood films of smeared peripheral blood.
Serology may be useful if the parasitemia is too low to detect or if the infection has cleared naturally or following treatment.
Serology may also be useful in the follow-up of documented cases of babesiosis or if chronic or persistent infection is suspected.
