What does polycythemia (JAK 2 negative) mean?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I am diagnosed with polycythemia (JAK 2 negative). I need more knowledge; my BM and JAK2 studies are within normal limits.

Kindly help.

Thank you.

Hello,

Welcome to icliniq.com.

Your present CBC report is not suggestive of polycythemia, especially polycythemia vera, which is a blood cancer condition (attachment removed to protect patient identity). Your JAK 2, EXON 12 study and bone marrow report are normal as per history. So, polycythemia vera is much less likely. Your high hemoglobin could be due to a secondary polycythemia cause. Secondary polycythemia is a purely benign condition. The causes for that include respiratory problems, cardiac problems, smoking, severe dehydration, etc.

I suggest you drink lots of water, especially three liters per day. Avoid smoking if you have a habit. It is advisable to repeat the CBC after a few days.

I hope this helps.

Thank you.
