REFERENCE RANGES: IgG <1:16
IgM <1:20
Elevated antibody levels to B. microti indicate
exposure to the organism. Human babesiosis
infection is transmitted by the bite of an
infected Ixodes tick or less frequently from
transfusion with blood from an infected donor.
Definitive diagnosis is made by identifying
intraerythrocytic organisms in peripheral blood.
In patients with low parasitemia, antibody
detection by IFA is recommended. IgG levels
greater than or equal to 1:1024 can be detected in
acute phase patients with parasites in blood
smears. The IFA assay can be used as a
seroepidemiologic tool to study the frequency and
distribution of B. microti in endemic areas
especially in persons with mixed infections also
involving Borrelia burgdorferi.
