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.
