Dengue, a common tropical viral disease, often has complications of thrombocytopenia causing bleeding and warranting blood transfusion. This is costly in low-income settings. We conducted an observational study using a relatively new parameter called immature platelet fraction which indicates regeneration of platelets by the bone marrow. Our study on 124 dengue patients showed a strong correlation between platelet count and immature platelet fraction and we observed that 96.1% and 97.4% patients showed rise in platelet count at 24 and 48 h, respectively. In the absence of bleeding, platelet transfusion was prevented in 64% of patients with an IPF level of 10% or more.
