Neisseria gonorrhoeae nucleic acid detection by probe-based assay (urine)
This test checks for the presence of gonorrhea bacteria in your urine using a molecular probe. It helps confirm if you have an infection caused by *Neisseria gonorrhoeae*, which can affect the genitals, rectum, or throat.
["A positive result means gonorrhea may be present; further testing or treatment may be needed."]

How the Test Works
The test uses a specialized probe to detect genetic material (DNA) from *Neisseria gonorrhoeae* in your urine. If bacteria are present, the probe binds to their DNA, triggering a signal that confirms infection. This method is highly sensitive and specific for gonorrhea.
What to Expect Before the Test
No special preparation is needed. You’ll provide a urine sample in a sterile container. Avoid urinating right before the test if possible, as it may dilute results. If you’re pregnant, inform your provider before testing.
What the Results Mean
A positive result indicates likely gonorrhea infection. A negative result means the test did not detect gonorrhea DNA, but other causes (like chlamydia) could still be present. Follow-up testing or treatment may be recommended.
When You Might Need This Test
Your healthcare provider may order this test if you have symptoms like unusual discharge, pain during urination, or genital sores, or if you’re at higher risk (e.g., sexually active without protection, recent sexual exposure).
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinical Significance: Gonorrhea is a sexually transmitted infection (STI) that can cause serious health issues if untreated, including pelvic inflammatory disease, infertility, or spread to the blood or joints. Early detection and treatment are crucial to prevent complications.
Short name
