Dengue is a common tropical mosquito-borne infection with a very high endemicity in Southeast Asia. The diagnosis of the disease is widely done by clinical observation of acute febrile illness accompanied with dengue triads from complete blood count (hemoconcentration, atypical lymphocytosis, and thrombocytopenia). For definitive diagnosis, either immunological test or polymerase chain reaction (PCR) test is required., In practice, the immunological test is cheaper and more widely used. Here, the authors tried to retrospectively analyze on the dengue immunoglobulin (Ig) test result among 115 patients with clinical diagnosis of dengue. Based on the analysis, the result is shown in [Table 1]. Based on this information, it can be seen that there are various patterns of Ig result among the cases with the clinical diagnosis of dengue. However, the acute illness (dengue IgM positive) can be completely confirmed in almost all cases. For the other cases with dengue IgM negative and dengue IgG positive (1.8%) indicated previous infection whereas the case with both dengue IgM and IgG negative might be on a window period. Based on the finding, it might seem that dengue diagnosis by clinical method is still applicable and can save the cost of immunological tests.
