What factors can affect the accuracy of the dengue test?

Several factors can affect the accuracy of the Dengue ELISA test. The timing of the test is critical; testing too early in the infection may result in false-negative results as antibodies may not be detectable yet. Cross-reactivity with other flaviviruses, such as Zika, West Nile, and yellow fever, can lead to false-positive results. The patient's immune response can also impact the test accuracy, with some individuals producing antibodies later or at lower levels. Additionally, the quality of the laboratory performing the test, including the reagents used, equipment calibration, and technician expertise, can influence the test's reliability. It is important to consider these factors and, if necessary, use additional diagnostic methods to confirm the results.
