What Affects the Test

There may be reasons you are not able to have this test or reasons why the results may not be helpful. One of the main reasons results may not be helpful is that the urine tested was not in your bladder for at least 4 hours before collecting the test sample.

What To Think About

  • A home test for a urinary tract infection (UTI) should be done under the direction of your doctor, so that abnormal test results caused by a problem other than a UTI will not be missed. Although a home test kit may detect the presence of a UTI, it can't provide information about the location of the infection. The infection may be in the kidneys, ureters, bladder, or urethra, or, in men, in the prostate gland camera.gif. More tests may be needed to determine the location and cause.
  • Positive test results do not always mean that you have an infection. If you have a positive test result, be sure to talk to your doctor. If you have symptoms of a urinary tract infection but your self-test is negative, contact your doctor for an evaluation.
  • Home test kits are not 100% accurate. If you continue to have symptoms of a urinary tract infection even though the test results show you do not have an infection (negative result), tell your doctor. Painful urination can be caused by other problems, such as a vaginal yeast infection or sexually transmitted infection. Frequent urinary tract infections can be a symptom of a serious problem, such as kidney stones, a tumor, or infection of the prostate gland. Do not use a home test as a substitute for regular medical checkups.
  • Some doctors may order another UTI test through a laboratory before prescribing antibiotics to treat an infection found using a home test kit.
  • Do not use medicine left over from treating another infection to treat a new UTI. Also, if your doctor has given you antibiotics for a UTI, be sure to take all of the antibiotics in your prescription, even if your symptoms go away before the prescription is gone. A UTI can return or get worse if you do not take the full course of antibiotics.
  • Many types of home test kits can be ordered over the Internet. If you have access to the Internet, you can find this information by searching for the type of test or the name of the manufacturer.
  • Some home test kits may come with cranberry or blueberry capsules or other medicine for use after the test. Any medicines that are included in your kit are not a substitute for follow-up with your doctor.
