Why This Biomarker Matters

Elevated monocytes in pericardial fluid indicate cardiac inflammation or infection. This test helps diagnose serious heart conditions like pericarditis.

Overview

Monocytes are large white blood cells that help fight infections and clear damaged tissue. This specialized test counts monocytes in pericardial fluid (fluid around the heart). Elevated monocyte counts in pericardial fluid may indicate pericarditis (inflammation of the heart lining), infection, or autoimmune disease affecting the heart. This test helps diagnose serious cardiac conditions and inflammatory states. Results are interpreted alongside other fluid analysis tests for comprehensive cardiac assessment.
