Laboratory Findings
- Cutaneous anergy is common in AIDS due to immunosuppression. Therefore a negative skin test for tuberculosis does not exclude the diagnosis of tuberculous pericarditis. Hence, pericardial biopsy is a more sensitive and preferred diagnostic test over smears and cultures.
- Other infections that cause pericarditis and myocarditis can be diagnosed by staining, culture and smears.
- Brain natriuretic peptide (BNP) may be elevated in presence of congestive cardiac failure.
