I am a 33 year old science graduate. I know that fever and high WBC count are defense mechanisms of our body to protect from infection. But my CBC blood report showed a low WBC count, and I have had fever for 5 days. How are low WBC count and fever related to each other?

You are correct that high WBC typically fights infection. Sometimes, viral infections can cause fever with low WBC counts by suppressing bone marrow temporarily. Dengue, viral fevers, and some bacterial infections can show this pattern. Continue hydration, rest, and monitor for any bleeding, rash, or worsening weakness. You can book a Repeat CBC and Dengue NS1/IgM test to monitor counts and rule out dengue if fever persists.

Sir, a 25 year old man is suffering from an acute attack of high fever with headache for the last 10 days. His blood test report is attached. My question is, is he suffering from dengue?

Answered by Apollo Doctors

I recently did an NS1 dengue test, which came out negative. Unsatisfied with the result, I repeated the test at a different clinic, and it showed a Dengue NS1 Antigen ratio of 3.5. All other parameters, such as platelet count and blood pressure, are normal. Can someone explain what this result means in detail, and what steps I should take next?

Answered by Apollo Doctors

I have had a fever since last Sunday. Blood tests showed: Dengue NS1 Antigen is Positive, IgM Antibodies is Negative, IgG Antibodies is Positive. I would like to know: Under what conditions or severity of dengue should a patient be hospitalized? Is there any specific medicine available in India for treating dengue?
