polycythemia

Increase in the haemoglobin content of the blood, either because of a reduction in plasma volume or an increase in red cell numbers. The latter may be a result of abnormal proliferation of red cell precursors (polycythemia vera, Vaquez-Osler disease).

Polycythemia

Polycythemia (also known as polycythaemia or polyglobulia) is a disease state in which the proportion of blood volume that is occupied by red blood cells increases. Blood volume proportions can be measured as hematocrit level. It can be due to an increase in the number of red blood cells (`absolute polycythemia`) or to a decrease in the volume o.....

polycythemia

Polycythemia is an increased number of circulating RBC. Most animals with increased PCV have relative polycythemia due to hemoconcentration. Splenic contraction can increase PCV by 10 to 15%. Absolute polycythemia is an increased total hemoglobin/RBC mass with normal plasma volume. Absolute polycythemia can be a primary myeloproliferative disorder ...
