When to see a doctorBy Mayo Clinic staff
A high red blood cell count is rarely an unexpected finding or simply discovered by chance. It's usually found when your doctor has ordered tests to help diagnose a condition you have. Talk to your doctor about what these results mean. A high red blood cell count and results from other tests may indicate the cause of your illness, or your doctor may suggest additional tests to monitor your condition.
