Ref:
Erythrocytosis is defined as an increase in red blood cell (RBC) mass, usually absolute , and is also associated with an increased hematocrit (HCT) and hemoglobin concentration. Although some use the term polycythemia interchangeably with erythrocytosis, the two are not synonymous. Polycythemia in precise terms refers to an increased number of any hematopoietic cell in blood, be it RBCs, platelets or leukocytes. An increase in RBC number (whether relative to changes in body water or an absolute increase in RBC mass) is more precisely called erythrocythemia, but this term is not in general use and we are currently using the term erythrocytosis instead of polycythemia for an increase in RBCs (relative or absolute). Complicating matters is the term polycythemia vera, which specifically refers to a type of chronic myeloid leukemia that only affects the erythroid lineage or, in other words, a chronic erythroid leukemia.
