I have been experiencing fever that comes and goes with chills. After taking paracetamol and antibiotics, the fever subsides. My blood test shows platelets at 1.6 lakh/cmm. Could you please advise if this could be dengue, or what might be causing these symptoms?

Answered by Apollo Doctors

My lab report shows that on the first day, my platelet count was 1,48,000, and on the next day, it dropped to 1,22,000. I am concerned about what this decrease means?

Answered by Apollo Doctors

Sir/Madam, According to my latest blood test, Dengue NS1 is positive, and my platelet count is 60,000. Please advise how serious this is and what steps I should take.
