When should I get a blood culture test?
A blood culture is a test that is used to diagnose an infection. It is done by taking a sample of the patient’s blood and placing it into a culture dish containing special media (agar). The agar contains nutrients that the bacteria need to grow.
The growth of bacteria in the culture dish may take up to 3 days. This test can help confirm or rule out infection as the cause of symptoms such as:- fever, chills, and redness around an injection site.
One important reason to get a blood culture is when you have had surgery, an injury, or a procedure and you have been in contact with other people who might be infected. A blood culture may also be needed if you are taking antibiotics and your doctor wants to make sure that they are working properly.
