Patients with polycythemia vera may often be [[asymptomatic]]. The diagnosis is often suspected on the basis of laboratory tests. Common findings include an elevated hemoglobin level or [[hematocrit]], reflecting the increased number of red blood cells; the [[platelet count]] or [[white blood cell count]] may also be increased. Because polycythemia vera results from an essential increase in erythrocyte production, patients have a low erythropoietin (EPO) level. | Patients with polycythemia vera may often be [[asymptomatic]].

Overview
Laboratory Findings
Patients with polycythemia vera may often be asymptomatic. The diagnosis is often suspected on the basis of laboratory tests. Common findings include an elevated hemoglobin level or hematocrit, reflecting the increased number of red blood cells; the platelet count or white blood cell count may also be increased. Because polycythemia vera results from an essential increase in erythrocyte production, patients have a low erythropoietin (EPO) level.
