Blood cultures

Why this is important:

Different types of bacteria can cause pneumonia. Your healthcare provider uses the blood culture test to determine which bacteria may have caused your pneumonia and which antibiotic should be prescribed. It is best to do the blood culture within 24 hours of arrival at the hospital and before antibiotics are started. It is also important to start antibiotics as soon as possible. Your healthcare provider also uses the blood culture to determine how to best treat you and if any precautions are necessary to prevent the spread of your illness.
