Hello doctor,

My Hb is 15.8 but HCT is 49.2 and total RBC count is 5.63. What is the reason? I fear about polycythemia. Is it possible to reduce HCT?



Welcome to

If you are a smoker, then stop smoking.

At this stage, secondary polycythemia is more common than primary and smoking is the most common reason for secondary.

Thank you doctor,

I am not having the habit of smoking or alcohol. I am studying final year MBBS. If HCT touches 49.2, is this polycythemia?



Welcome to

Do not worry, repeat your CBC after four to six weeks time and upload the report.

With hemoglobin at 15.8, hematocrit should not be 49. Even if it is true, it is the upper limit of the normal range.

I suggest you repeat the test. If it is persistently high, you can do JAk 2 mutation and erythropoietin levels to rule out primary PV.
