Bacterial Endocarditis
Diagnosis

A blood test is the primary test for bacterial endocarditis. Three to five blood samples may be taken in a 24-hour period to determine the presence of the bacteria.

A urine sample also may indicate the presence of infection but is not adequate by itself for the diagnosis.

An echocardiogram may detect an abnormality, such as a mass on a heart valve or on the heart wall surface, called a vegetation.
