2025年2月14日 · A high RBC count, known as erythrocytosis or polycythemia, occurs when the body produces too many red blood cells, leading to thicker blood and potential complications such as blood clots or reduced circulation.

Having a high red blood cell (RBC) count means that the number of RBCs in the bloodstream is higher than normal. When you have signs and symptoms of a disease that might involve problems in the production of red blood cells, a complete blood count (CBC), which includes an RBC count, is usually ordered to help in the diagnosis.
