Aerobic blood culture is a laboratory test used to identify the presence of bacteria, fungi, or other microorganisms in a patient’s blood sample. This test is performed when a patient is suspected to have a bloodstream infection or sepsis, a severe and potentially life-threatening condition. The blood sample is incubated for several days in a special culture medium that promotes the growth of microorganisms. If bacteria or fungi are present, they will grow in the culture, and their species can be identified using various laboratory techniques. The test also determines the susceptibility of the microorganisms to different antibiotics, which is crucial for selecting the appropriate treatment. Results of this test are used by healthcare providers to diagnose and manage bloodstream infections, helping to improve patient outcomes.
