Culture - blood
A normal value means that no microorganisms grew in the laboratory dish.
Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
A positive result usually means that you have bacteria or other microorganisms in your blood. However, contamination of the blood sample can lead to a false-positive result, which means you do not have a true infection. Your health care provider can help determine the difference.
