<s>[INST] I had a dengue patient where his platelet counts were 60, 20, 65, 15 over 4 days period. After the 4th day the test showed up trend platelet result. No blood transfusion was given. Just wondering the explanation for the platelet fluctuation for the first 4 days. Is it normal and why? [/INST] Hi, dear. I have gone through your question. I can understand your concern. Your platelet count results are somewhat problematic without any platelets' transfusion. Without any external infusion platelet count should constantly decrease then remains static and then start to rise in dengue patients.  Hera its falling and rising every day So there may be some instrumental error in platelet count report.  You should go for repeat test. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
