Overview
Laboratory findings associated with the diagnosis of polycythemia vera include erythrocytosis, leukocytosis, and thrombocytosis. The most sensitive test for polycythemia vera is JAK2 V617F mutation testing in the peripheral blood. A specific finding in patients with polycythemia vera is low erythropoietin level.
Laboratory Findings
Laboratory findings associated with polycythemia vera include:[1][2][3][4][5][6]
- Erythrocytosis
- Increased hemoglobin
- Thrombocytosis
- Leukocytosis
- Increased basophils and eosinophils
- The following blood levels may be elevated in blood chemistry (non specific):
- Blood urea nitrogen (BUN)
- Creatinine
- Phosphate
- Lactate dehydrogenase (LDH)
- Alanine aminotransferase (ALT)
- Aspartate transaminase (AST)
- Uric acid
- Peripheral blood mutational testing
- Bleeding and clotting factor
- Erythropoietin (EPO)
- It is usually low in polycythemia vera but can be normal in about 20% of patients.
- It is usually high in secondary polycythemia vera.
- Elevation of white blood cells, red blood cells, and platelets
