<s>[INST] My platelet count has been elevated over the past year and a half, and my doctor has said it is not a significant finding and has not ordered any additional testing. I have no symptoms. When I read online, it says I may have cancer or an infection, but I don t have an infection. Is there any cause for concern? [/INST] Hello,There is a condition called essential thrombocytosis, it's due to elevation of platelet count idiopathically.If you do not have any symptoms, you should not worry about it because its main function is to clot blood fast enough while bleeding.Hope I have answered your query.
