A blood culture test is performed to see if you have an infection in your blood (septicemia). This test may be ordered if you have fever, chills, nausea, or fatigue, and your health care provider suspects septicemia.
Your sample will be tested for the presence of bacteria or fungi that can cause septicemia.
Tell your health care provider if you are taking antibiotic medicine. It is recommended that blood samples be collected before starting this medicine. If blood cultures are performed while you are on an antibiotic, the blood samples should be collected shortly before you take a dose of the medicine.
Your test results will be reported as either positive or negative. For this test, a normal finding is a negative blood culture.
A positive blood culture test may mean that you have septicemia or blood poisoning caused by bacteria or fungi. Septicemia can indicate a serious infection.
Talk with your health care provider about what your results mean.
