Common questions
When is the best time to take this test?
It can be done at any point during a fever, since the combined markers cover both early and later phases of illness.
What does a non-reactive result mean?
It makes dengue less likely, but if symptoms continue, repeat testing may be advised because antibodies can take time to appear.
