Bartonella henselae Antibody (IgG) with Reflex to Titer Test
This test measures IgG antibodies to Bartonella henselae in a blood sample. If antibodies are detected, the sample reflexes to a titer test to quantify the antibody level.
About this test
The test measures levels of IgG antibodies against Bartonella henselae in a 1 mL serum sample using immunofluorescence assay. Results may aid in the diagnosis of recent or current Bartonella henselae infection.
People considering this test are typically being evaluated by a clinician for possible recent or current Bartonella henselae infection, since Quest describes the results as an aid to that specific diagnosis rather than as a general screening test.

Additional details
What this test looks at
The single analyte reported is the IgG antibody screen for Bartonella henselae. A detected result on that screen automatically reflexes to a titer test on the same serum sample, so the two results are reported together rather than requiring a separate order from the ordering clinician.
This test isn't part of the Celio Health store at the moment, so it can't be ordered or requested here. The test menu lists everything that can.
Laboratory results should always be interpreted by a licensed clinician who knows your health history. This page is information about a test, not medical advice.
Frequently asked questions
What does this test measure?
It measures IgG antibodies against Bartonella henselae 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 IgG antibodies are detected?
A detected result reflexes to a titer test to quantify the antibody level.
How does this test show a recent infection?
Quest describes recent infection as shown by seroconversion or a rising IgG titer when acute and convalescent samples are compared on the same assay run.
