Overview
Laboratory findings consistent with cardiac myxoma include anemia, leukocytosis and elevated erythrocyte sedimentation rate. However, these results are generally non-diagnostic.
Laboratory Findings
The clinical utility of laboratory tests in the diagnosis of cardiac myxoma is low.[1]
Blood tests
There is no specific blood test for the diagnosis of cardiac myxoma. However, constitutional symptoms are associated with the following blood count (CBC) findings:[2]
- Anemia - Normochromic or hypochromic.
- Leukocytosis
- Elevated erythrocyte sedimentation rate(ESR)
- C-reactive protein
- Serum globulin level - Hypergammaglobulinemia
- IL-6 - Atrial myxoma cells are capable of producing IL-6. Therefore, IL-6 is commonly used as a marker of recurrence in cardiac myxomas.[3]
