What is the most effective method for etiological diagnosis of infective endocarditis?
The most effective method for etiological diagnosis of infective endocarditis is the broad-range polymerase chain reaction (PCR) method. This method has been used for over three years and has been found to be very effective in identifying the cause of endocarditis. Other methods such as the LightCycler SeptiFast test, blood culture, and culture-based methods are also used to diagnose the cause of endocarditis, but the PCR method is the most accurate and reliable.
