Why This Test Is Done

Your healthcare provider may recommend this test if you have symptoms like frequent urination, pain or burning during urination, fever, or signs of a urinary tract infection (UTI). It helps determine if the infection is caused by *Staphylococcus aureus*, which can guide treatment choices.

How the Test Works

This test is qualitative, meaning it only tells you whether the bacteria’s genetic material is present or not, rather than measuring its exact amount.

What to Expect Before the Test

No special preparation is needed. You may urinate normally before the test, but avoid using urinary antiseptics or certain medications that could interfere with results for 24 hours before testing.

What to Expect During the Test

The test involves a brief procedure where a sterile probe is inserted into your bladder to collect a urine sample. You may feel mild pressure or discomfort, but it usually takes only a few minutes. The probe is then removed, and the sample is analyzed immediately.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical Significance

Short name

Can I take antibiotics before this test?
No, it’s important to avoid antibiotics for at least 24 hours before this test to ensure accurate results. If you’ve already started antibiotics, let your provider know, as they may need to adjust testing or interpretation.
