==Overview==
[[Polycythemia]] is defined as increasing the [[hemoglobin]] (>16.5 g/dl in men or >16 g/dl in women) or [[hematocrit]] level (>49%in men or >48% in women). This elevated level might be due to declining the plasma volume (relative or spurious [[polycythemia]]) or rising the number of [[red blood cell]]s (true [[polycythemia]]).

Synonyms and keywords: Approach to polycythemia, Approach to high hemoglobin level, Approach to high red blood cell count

Overview

Polycythemia is defined as high hemoglobin (>16.5 g/dl in men and >16 g/dl in women) or hematocrit level (>49%in men and >48% in women). This elevated level might be due to declining the plasma volume (relative or spurious polycythemia) or rising the number of red blood cells (true polycythemia).

Causes

Life Threatening Causes

Common Causes

Primary polycythemia [2]
Secondary polycythemia

Diagnosis
