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 11 month old baby has been having fever for the past 15 days. Only her head feels very hot, and it occurs mainly at night. Today, we did a blood test, which shows very low hemoglobin and a blood infection. What should I do, and what treatment is needed?

I am having mild fever, throat infection with no cough, body aches, and weakness. I had erythromycin with paracetamol. My blood test report shows ESR 16 mm at 1 hour with normal up to 15, lymphocytes 4085 cu/mm with normal 1000 to 4000, and eosinophils 570 cu/mm with normal up to 500.

For the past one month, I have been feeling fatigued and experiencing a low grade fever. My recent investigations include LFT, KFT, and CBC, which showed SGPT at 57. My urine report is normal, chest Xray is normal, Mantoux test is negative, and whole abdomen ultrasound is normal. My body temperature ranges from 96F to 100.2F. I am unsure about the cause of my symptoms and would like to know the possible reason and which specialist I should consult.
