Of 52 patients with dengue virus infection diagnosed using a standard hemagglutination inhibition test, 41 patients demonstrated dengue virus infection using the IC test. Half of the serum samples collected on day 3 after the onset of fever were positive for dengue antibodies, and all were positive on day 6 after symptom onset. In comparison with the hemagglutination inhibition test, the rapid IC test showed 79% sensitivity and 95% specificity. The efficiency of the test was 86%. The IC test showed good agreement with the hemagglutination inhibition test (k=0.72). The IC test is quick to perform and provides early diagnosis of dengue virus infection.Mahidol UniversityImmunology and MicrobiologyMedicineArticleSCOPUS10.1007/s10096-001-0691-z
