: Staphylococcus species culture

: What This Test Measures

: The test looks for Staphylococcus bacteria in a sample such as a wound swab, pus, blood, urine, or another body fluid or tissue. If Staph grows, the laboratory identifies the species, which can help distinguish common types such as Staphylococcus aureus from other Staphylococcus species.

: Why It May Be Ordered

: A healthcare provider may order this test when there are signs of a bacterial infection, such as redness, swelling, pus, fever, or an infected wound. It can also be used when a staph infection is suspected in the blood, urinary tract, or other body sites.

: How the Sample Is Collected

: The sample depends on where the infection is suspected. Common specimens include a swab from a wound or skin area, a sample of pus or fluid, blood, or urine. Collection is usually quick and may cause mild discomfort, depending on the site.

: How Results Are Interpreted

: A positive result means Staphylococcus bacteria grew from the sample and were identified. A negative result means no Staphylococcus was detected under the testing conditions. Results must be considered together with symptoms, the collection site, and other laboratory findings; a culture alone does not always prove infection versus normal skin bacteria.
