The Blood Culture (Aerobic) test is used to detect the presence of bacteria or fungi in the blood, indicating an infection known as bacteremia or fungemia . This test involves taking a blood sample and incubating it in an aerobic environment (with oxygen) to allow any present microorganisms to grow. If bacteria or fungi are present, they will multiply and can be identified through further testing.

The test helps diagnose serious infections such as sepsis, endocarditis, or infections originating from other parts of the body, like the lungs or urinary tract, that have spread into the bloodstream. Identifying the specific microorganism responsible allows for targeted antibiotic or antifungal treatment.
