Fluid Analysis – part 7 – Pericardial fluid Analysis
- Pericardial fluid is aspirated and is tested.
- Normally there is 10 to 50 mL pericardial fluid between the pericardial serous membrane.
- This pericardial fluid formation is due to change in the permeability of the membrane which may be because of infection (pericarditis), malignancy, injury, and metabolic disorders like uremia.
|The pericardial fluid||Clinical significance|
|Clear and pale||Normal|
|Grossly bloody||Cardiac puncture, and anticoagulant medications|
|Blood tinged||Infection and malignancy|
|Milky||Chylous and pseudonymous|
|Neutrophils||Increased in bacterial infection (>1000/cmm)|
|Gram stain||Bacterial endocarditis|
|AFB stain||Tuberculous infection|
|Malignant cells||Metastatic carcinoma (lung, breast)|
|Adenosine deaminase||Tuberculous infection|
