I recently had some tests done. My main symptoms are feeling feverish (slightly warm body), weakness/loss of energy, and slight giddiness. My reports show: ESR is 27 (normal 0 to 19), increased RBC (erythrocytosis), increased platelets (thrombocytosis), and very low Vitamin D3 (7.54). What could be the cause of increased RBC, platelets, and ESR? Does this indicate an active infection in the body?

Feeling feverish, weak, and giddy along with raised ESR, RBC, and platelets may suggest inflammation, dehydration, or a possible low grade infection. Low Vitamin D3 can also cause fatigue and body discomfort. These results do not point to anything serious on their own but should be evaluated with symptoms. It is best to repeat CBC, CRP, and Vitamin D Test to track trends.

My wife had dengue fever last week and was hospitalized. She was discharged 3 days ago, but this morning she developed a fever again. We gave her Dolo 650 as per the doctor suggestion, which reduced the fever, but it returns whenever she sleeps and wakes up. We did a CBC test today: Hemoglobin 10.4, RBC normal, Platelets 295, WBC 14.5. I am concerned, does she need to be hospitalized again? Please advise

I was having low grade fever and body ache. The doctor advised me to get a dengue test. My report shows IgM and IgG non reactive, but NS1 is reactive. What does this mean?
