Which of the following would NOT cause a falsely negative blood culture result?

Falsely negative results happen when a pathogen is present in the bloodstream but the culture fails to recover and grow it. Not incubating long enough, using the wrong culture bottle, or delays in transport can each reduce the likelihood of detecting the organism that is actually there, leading to a false negative. Failing to disinfect the collection site, on the other hand, increases skin flora contamination and tends to produce mixed growth or false positives rather than a missing pathogen. So this condition would not cause a falsely negative result.
