: Mycoplasma Culture, Exudate, Qualitative

: What This Test Looks For

: The test looks for Mycoplasma bacteria in a sample of exudate, which is fluid or discharge collected from an affected area such as the eye, ear, throat, or a wound. Mycoplasma are very small bacteria that can cause infections of the respiratory tract, eyes, and other sites. Culture attempts to grow the organism so it can be identified.

: How the Sample Is Collected

: A healthcare provider collects the exudate using a swab or similar collection device from the affected area. The sample is then sent to a laboratory, where it is placed in special culture media designed to support the growth of Mycoplasma. Because these organisms can be slow-growing and fastidious, results may take longer than for many routine bacterial cultures.

: What a Positive Result Means

: A positive (qualitative) culture means Mycoplasma organisms grew from the sample, which supports the presence of a Mycoplasma infection at the collection site. Your provider will interpret this together with your symptoms, examination findings, and other test results to decide on appropriate treatment.

: What a Negative Result Means

: A negative culture means Mycoplasma did not grow from the sample under the test conditions. This can suggest the organism is not present, but it does not entirely rule out infection, because Mycoplasma can be difficult to grow and sampling or handling can affect results. Your provider will consider whether repeat or alternative testing is needed.
