Overview
Laboratory findings associated with the diagnosis of polycythemia vera include erythrocytosis, leukocytosis, and thrombocytosis.[1]
Laboratory Findings
Laboratory findings associated with polycythemia vera include:[1][2][3][4][5][6][7]
- Erythrocytosis: This is a hallmark laboratory finding in polycythemia vera.
- Increased hemoglobin: Hemoglobin is usually more than 16.5 g/dl. Elevated hemoglobin corresponds with elevated red blood cell mass.
- Increased granulocytes of all types: Polycythemia vera is characterized by panmyelosis (elevation of cell counts of all 3 cell lines).
- Increased basophils and eosinophils
- Thrombocytosis
- Leukocytosis
- Blood chemistry
- The following blood levels may be elevated (but these are non-specific):
- Blood urea nitrogen (BUN)
- Creatinine
- Phosphate
- Lactate dehydrogenase (LDH)
- Alanine aminotransferase (ALT)
- Aspartate transaminase (AST)
- Uric acid
- Bleeding and clotting factor
- The following blood levels may be elevated:
- Prothrombin time (PT) or international normalized ratio (INR)
- Partial thromboplastin time (PTT)
- Cytochemistry
- Flow cytometry
- Cytogenetics
- Fluorescent in situ hybridization (FISH)
- Polymerase chain reaction
- Vitamin B12
- Erythropoietin (EPO)
- Low in polycythemia vera
- High in secondary polycythemia
- High in relative polycythemia
