What Is a Urine Culture and Sensitivity Test?
A Urine Culture and Sensitivity Test is a lab test that checks for bacteria in your urine. Doctors often call this a urine infection test. This test helps find out if you have a urinary tract infection (UTI). It also shows which medicine can best treat the infection. Because of this, the test is very important for proper treatment.
During the test, your urine sample is placed in a special dish. If bacteria grow, the lab checks which antibiotics can stop them. This process is called sensitivity testing. In short, the test helps doctors choose the right medicine for you.
Why Is the Test Done?
Doctors order a Urine Culture and Sensitivity Test for several reasons. For example, you may have symptoms like burning while peeing, frequent urges to urinate, or cloudy urine. Sometimes, your doctor may want to confirm a urine infection or check if treatment is working.To find out if you have a urinary tract infection (UTI)To identify the type of bacteria causing the infectionTo choose the best antibiotic for your infectionTo check if an infection has cleared after treatment
Because the test gives clear answers, it helps prevent the use of the wrong medicine.
How Is the Test Performed?
The urine infection test is simple and safe. First, you will be asked to give a urine sample. Most often, you will need to collect a “midstream” sample. This means you start urinating, then collect urine in a clean cup halfway through. This method helps avoid germs from your skin getting into the sample.Wash your hands well before starting.Clean the area around your genitals with a wipe, if provided.Begin urinating into the toilet.After a few seconds, collect urine in the cup.Finish urinating into the toilet.Close the cup tightly and give it to the nurse or lab staff.
After you give your sample, the lab will test it for bacteria. If bacteria are found, they will check which antibiotics work best. This is how urine culture works to guide treatment.
What Do the Results Mean?
Understanding urine sensitivity results can seem confusing, but your doctor will explain them. If no bacteria grow, your test is negative. This means you likely do not have a urine infection. If bacteria do grow, the test is positive. The lab will list which bacteria are present and which antibiotics can treat them.Negative result: No infection found.Positive result: Infection found; bacteria type and best antibiotics listed.
Sometimes, the test may show mixed bacteria. This can mean the sample was not clean. In that case, your doctor may ask for a repeat test. Because the results guide treatment, always follow your doctor’s advice.
