What is this test?

This test measures antibodies your immune system has produced in response to Ebola virus. A titer is a laboratory measurement used to estimate the amount of these antibodies.

Why might I need this test?

It may be used in selected situations to help document a previous Ebola infection or immune response, particularly when there is relevant travel, exposure, or occupational history. It may also be used as part of an evaluation ordered by public-health or infectious-disease specialists.

How is the test performed?

A blood sample is collected, and the liquid portion, or serum, is separated. A laboratory method then detects and estimates the level of Ebola virus antibodies.

How do I prepare for the test?

No special preparation is usually required. Tell your clinician about any possible Ebola exposure, recent travel to an affected area, prior Ebola infection, or relevant vaccination history because these details can affect interpretation.

Clinical interpretation

Frequently asked questions

Does a positive antibody test mean I currently have Ebola?
Not necessarily. A positive result indicates that Ebola virus antibodies are detectable, which may reflect previous infection or vaccination. Other testing may be needed to evaluate an active infection.
Can this test rule out an Ebola infection?
No. Antibodies may not be present early in an infection, so a negative antibody result does not completely exclude Ebola. Your clinician will consider symptoms, exposure history, and the timing of testing.
Why was an Ebola virus antibody titer ordered?
It is usually ordered for a specific exposure history, prior infection assessment, immune-response documentation, or public-health evaluation. Its usefulness depends on your circumstances, so discuss the reason for testing with your clinician.
