A dengue fever test is a simple blood test that checks for the presence of the dengue virus in your blood. Doctors generally suggest the dengue NS1 test for early detection. Here is a quick guide for dengue lab tests that can help you. In most cases, a complete blood count is recommended if your doctor suspects dengue. However, it is a nonspecific test because it doesn’t help to confirm the presence of the dengue virus or detect the type of virus. For acute dengue diagnosis, clinicians should order a nucleic acid amplification test (NAAT) and an IgM antibody test or an NS1 antigen test and an IgM antibody test. If dengue is suspected, clinicians should provide appropriate management without waiting for diagnostic test results.
