What is this test?
This serology test measures total antibodies. It assesses the immune response in blood rather than directly detecting the organism and does not establish a diagnosis by itself.
Why might it be ordered?
- For a clinical concern, known exposure, or a need to clarify an immune response.
- As part of a marker combination used to assess different stages or past exposure.
- For follow-up only when the clinician and method define a meaningful comparison over time.
What sample is needed?
Serology normally uses a blood specimen. Confirm the exact material and whether other markers should be measured at the same time.
How should you prepare?
Special dietary preparation is usually unnecessary. Follow laboratory instructions and report recent vaccination, treatment, and the possible exposure date.
How should you understand the result?
The result reports total antibody reactivity across the classes covered. It may not distinguish recent from past exposure and is assessed with other markers.
