Pericardial Fluid (Pericardium) Content: Total Protein by Bromocresol Green Method

Why This Test Is Done

Your doctor may order this test if you have symptoms like chest pain, shortness of breath, or signs of fluid buildup around the heart. It helps diagnose conditions such as pericarditis, cardiac tamponade, or other pericardial diseases.

What to Expect Before the Test

No special preparation is needed. The fluid is typically collected through a procedure called pericardiocentesis, where a needle is inserted into the pericardial sac under guidance from imaging (like an ultrasound). You may feel discomfort but should not experience significant pain.

What the Results Mean

Protein levels in pericardial fluid can vary widely depending on the cause. Elevated levels often suggest inflammation, infection, or bleeding into the pericardium. Lower levels may be normal or could indicate other conditions like constrictive pericarditis.

Common Conditions Linked to Abnormal Results

High protein levels may be linked to conditions such as pericarditis (inflammation of the pericardium), cardiac trauma, or malignancies that spread to the pericardium. Low or normal levels may be seen in conditions like constrictive pericarditis or benign pericardial effusion.
