Reference Range
Glucose Pericardial Fluid: Biochemical analysis of pericardial fluid (pH, total protein, glucose, LD) is of limited clinical value in most cases. Light's criteria, originally established for pleural effusions, have been shown to classify nearly all pericardial fluids as exudates regardless of etiology. (Am J Cardiol. 2007;99(9):1294; Heart. 2020;106(7):541.)
Glucose Pleural Fluid: Pleural fluid glucose of less than 60 mg/dL or pleural fluid glucose/serum glucose ratio of less than 0.5 is abnormal. Abnormal pleural fluid glucose is seen in rheumatoid pleuritis and parapneumonic exudates. It can also be seen in malignancy, tuberculosis, SLE and esophageal rupture.
