Additional Dosage Information Your dosage will be based on your medical condition, age, and other factors. The usual dose for adults is milligrams mg to mg, three times a day. This is not recommended because traces of menses can produce a false positive WBC Leukocyte result.
Your healthcare professional may recommend that you test your urine again after completing the antibiotic treatment.
If the AZO Test Strips is positive, contact your healthcare professional and always follow instructions for taking an antibiotic even if the strip result is negative. Bacteria require time to convert nitrates to nitrites. Testing in the morning, assuming you have slept for at least four hours without urinating, allows the bacteria sufficient time to complete the conversion and provide a rich sample for testing. Do not refrigerate and do not store in the bathroom. Most likely the urine sample test was contaminated.
We recommend testing again, making sure the sample is clean and free of soap, vaginal discharge, menses or some other contaminant.
Use the following table to determine what your test results mean. Remember, they are only one piece of information your doctor needs in order to treat you. When trace LEU occurs or if you have symptoms, test again the following day with your first morning urine using a new test strip.
If you get another trace LEU or if you still have symptoms, consult your physician. Consult your physician immediately. Repeat the test next time you urinate using a new test strip. Make sure to wash the genital area first. If LEU is still positive, consult your physician. AZO Test Strips have the same test pads as the tests used by most doctors. Each person's body chemistry is unique and will create a different shade of color on the test pads. Under certain conditions, you may get a negative result even though you have a UTI.
If your infection is caused by bacteria that does not change nitrate to nitrite, if your diet does not include nitrates, or if the urine has not been held in the bladder long enough at least 4 hours , you will get a negative nitrite result. Always contact your healthcare professional when UTI symptoms persist.
Most substances will not interfere with the test. However, some medications can affect the color of your urine, making it difficult to properly match the colors. For example, if you take more than mg of Vitamin C in 24 hours, you may obtain a false negative nitrite result. The drug tetracycline may also cause a false negative WBC result.
