Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate.

Reference Ranges:  IgG  <1:64
                              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.
