BABMI / BABG-M
BABESIA MICROTI AB, IGG

Test Code BABMI / BABG-M 
Test BABESIA MICROTI AB, IgG 
Methodology Immunofluorescence Assay (IFA) 
Description Useful for:
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. 

Specimen Draw blood in either a plain red-top tube or serum gel tube. Spin down and send 0.5 mL (minimum 0.15 mL) in a screw capped plastic vial. 
Reference Values <1:64

Interpretation:
A positive result of an indirect fluorescent antibody test (titer > or = 1:64) suggests current or previous infection with Babesia microti. In general, the higher the titer, the more likely it is that the patient has an active infection. Patients with documented infections have usually had titers ranging from 1:320 to 1:2,560.

NOTE: Previous episodes of babesiosis may produce a positive serologic result.
