Answer 4 Effusion due to CHF. Most pleural effusions have a pleural fluid glucose concentration similar to that of blood glucose, including effusions due to CHF and nearly all transudates. The following exudates may have a low (< 60 mg/dL) pleural fluid glucose concentration: rheumatoid pleurisy, parapneumonic effusion or empyema, malignant effusion, tuberculous pleurisy, lupus pleuritis, and esophageal rupture.3 REFERENCES 3. Sahn SA.
