For patients with suspected bacterial endocarditis, 2 to 3 sets taken at different times should be sufficient to establish a diagnosis.
Collect blood cultures 20 minutes apart. If patient is too ill to wait 20 minutes, prior to administering antibiotics, collect the first set from one site and the second from a different site.
Please provide clinical details. Extended incubation is required for query endocarditis, brucellosis or fungal infection.
Transport bottles at room temperature.
