May 8, 2023 · Polycythemia, derived from poly (many) and cythemia (cells in the blood), is a condition defined as an abnormal increase in the red blood cell (RBC) mass. For a normal healthy adult, the RBC mass is 23 to 29 mL/kg in females and 26 to 32 mL/kg in males.[1][2] Patients with hematocrit values greater than 51% and 48% and hemoglobin values greater than 185g/L and 165 g/L in males and females ...

Jun 2, 2022 · Polycythemia is a blood disease characterized by overproduction of red blood cells. There are two types, primary and secondary. Primary polycythemia, or polycythemia vera, is typically caused by an acquired JAK2 mutation. Secondary polycythemia is polycythemia developing secondarily to another condition that causes increased erythropoietin ...

Males with Hct greater than 0.52, and females with Hct greater than 0.48, with risk factors for apparent erythrocytosis or signs and symptoms suggestive of secondary erythrocytosis, and without signs or symptoms suggestive of polycythaemia vera, should be retested in two months following attempts to address apparent/secondary erythrocytosis.

May 10, 2024 · Polycythemia vera is a rare blood cancer caused by a genetic mutation in the bone marrow, while secondary polycythemia is a reactive response to an underlying condition or external factors. Understanding the differences between these conditions is crucial for accurate diagnosis and appropriate management.
May 20, 2023 · Polycythemia, also called erythrocytosis, refers to increased red blood cell mass, noted on laboratory evaluation as increased hemoglobin and hematocrit levels. Polycythemia vera is a subtype of polycythemia and can be associated with the overproduction of more than just the erythrocytic lineage. The clinical significance of erythrocytosis, due ...

JPPolycythemia is a general term for the presence of too many blood cells. Erythrocytes are far more numerous than leukocytes and platelets, so the term is actually synonymous with erythrocytosis. No consensus regarding usage has ever been reached, and in each instance, the term erythrocytosis or polycythemia is used as originally described ...
