Babesia microti Antibodies (IgG, IgM) with Reflex to Titers Test
This test measures IgG and IgM antibodies against Babesia microti, a tickborne parasite, in a blood sample. A detected result on either antibody reflexes to titer testing.
About this test
The test uses immunofluorescence assay on a serum sample to detect IgG and IgM antibodies to Babesia microti. Positive results may reflex to titer testing to help characterize antibody levels.
Testing may be used to help in the diagnosis of babesiosis, considered alongside clinical evaluation and risk of tick exposure, particularly in northern and upper Midwestern United States regions. Quest notes that symptoms of babesiosis can be nonspecific and overlap with other tickborne illnesses such as anaplasmosis, ehrlichiosis, and Lyme disease, that negative results can occur early in infection, and that nucleic acid amplification testing is preferred for acute diagnosis.

Frequently asked questions
What does this test measure?
It measures IgG and IgM antibodies against Babesia microti in a serum sample using immunofluorescence assay.
How is the sample collected?
The test uses a 1 mL serum sample from a routine blood draw.
Do I need to prepare for this test?
No preparation instructions are listed for this test, though people follow any instructions their ordering clinician provides.
What happens if the IgG or IgM antibody is detected?
A detected result reflexes to titer testing for that antibody to help characterize the antibody level.
Can this test miss an early infection?
Quest notes that negative results can occur early in infection and that nucleic acid amplification testing is preferred for acute diagnosis.
