: Dengue hemorrhagic fever (DHF) is an acute fever disease with high mortality and morbidity in many regions of the world. Leucopenia and thrombocytopenia are two of several laboratory findings that could be found in the course of DHF. This was an analytical retrospective study with a cross sectional design. Samples were patients diagnosed with DHF in Prof. Dr. R.D Kandou General Hospital Manado during the period of 2012. The inclusion criteria were patients <15 years, were diagnosed as DHF according to WHO 1997 criteria, and were examined for platelet and white blood cell count. This study used the medical record data which were analyzed statistically by using the Pearson's correlation test. There were 137 children with DHF during the period of 2012. Samples were 56 children that fulfiled the inclusion criteria. The Pearson correlation test showed a P value 0.801 and correlation coefficient r = -0.034 that indicated that there was a negative correlation which was not significant. Conclusion: There was no significant correlation between the number of thrombocytes and leukocytes in children with dengue hemorrhagic fever
