However microorganisms are present on the skin surface. • A blood culture test is performed to see if you have an infection in your blood (septicemia). • At least two blood samples from two different veins are required for this test. This gives a better chance of finding an infection and ruling out a false-positive result. • The normal result for this test is a negative blood culture After inoculating the culture vials, they are sent to the clinical pathology microbiology department. Here the bottles are entered into a blood culture machine, which incubate the specimens at body temperature. The blood culture instrument reports positive blood cultures (cultures with bacteria present, thus indicating the patient is bacteremia)
