: Microorganism Preliminary Identification and Quantitation by Aerobic Culture, Neutrophil Assessment

: What This Test Measures

: The test combines two kinds of information. First, it grows microorganisms under aerobic conditions, meaning in the presence of oxygen, to see whether bacteria or other organisms are present and to give a preliminary identification of what they are. Second, it reports on neutrophils, a type of white blood cell often seen when the body is fighting an infection or dealing with inflammation.

: Why Your Clinician May Order It

: Your clinician may order this test when an infection is suspected, when a wound or body fluid needs evaluation, or when earlier results suggest inflammation. The combination of organism detection and neutrophil findings can help distinguish infection from other causes of inflammation and guide decisions about further testing or treatment.

: How the Sample Is Collected

: The specimen depends on your situation and may be a swab, fluid, tissue, or another sample your clinician selects. The sample is sent to the laboratory, where it is cultured under aerobic conditions and examined microscopically for neutrophils and microorganisms. Collection is typically quick, though some sites may cause brief discomfort.

: What the Results Mean

: Results describe whether microorganisms were seen or grown, what they preliminarily appear to be, and whether neutrophils are present. A positive culture with neutrophils can support an infection, while the absence of growth or neutrophils may point away from certain infections. Your clinician interprets these findings together with your symptoms, exam, and other tests; results alone do not diagnose a condition.
