What do negative results in a dengue test mean?

A negative result in a Dengue ELISA test indicates that no dengue antibodies or antigens were detected in the blood. This could mean that the person does not have a dengue infection or that the test was done too early, before the antibodies or antigens are detectable. It is important to consider the timing of the test and the clinical symptoms. If the test is negative but symptoms persist, repeat testing or additional diagnostic methods, such as PCR, may be recommended to confirm the absence of infection. Negative results should be interpreted with caution, especially in areas where dengue is endemic, and should not rule out other potential causes of febrile illness.
