What does a borderline result in dengue test mean?

A borderline or equivocal result in a Dengue ELISA test indicates that the antibody or antigen levels detected are not clearly positive or negative. This can happen for several reasons, including testing during the early or late stages of infection when antibody levels are low, or due to cross-reactivity with other flaviviruses. Borderline results require careful interpretation and may necessitate repeat testing or additional diagnostic methods to confirm the presence or absence of dengue infection. It is important to discuss borderline results with your healthcare provider, who can evaluate the results in the context of your symptoms, medical history, and potential exposures.
