Patient's Query

Hello doctor,

I had a blood test today and the results show hemoglobin is 18.05 and the RBC is 5.8 and hematocrit is 42 %. Should I be worried?

Hi,

Welcome to icliniq.com.

Your hemoglobin and RBC are certainly high. So your diagnosis can be polycythemia. It can be secondary erythrocytosis for which you can investigate with EKG and chest X-ray to rule out the cardiac or respiratory cause. If you have any dehydration or prolonged fasting history, then provide history regarding that. Kindly provide your full CBC report and any clinical history if present to guide you further. After your reports and total WBC count review, I can guide you further.

Same symptoms don't mean you have the same problem. Consult a doctor now!
