Will common foods, alcohol, or medications affect my test results?

Zoe Updated by Zoe

Most substances will not interfere with the test. However, some medications, like Soothe, can affect the color of your urine, making it difficult to properly match the colors. For example, if you take more than 500 mg of Vitamin C in 24 hours, you may obtain a false negative nitrite result. The drug tetracycline may also cause a false negative leukocyte result. If you are having difficulty reading the test strip or getting a negative result while experiencing UTI symptoms, contact your healthcare professional immediately. 

We do not recommend using Clarify while taking Soothe or Uqora Target. Soothe contains phenazopyridine hydrochloride, an orange organic dye. This dye enters the urine to take effect and relieve UTI pain. However, it also turns the urine bright orange! Since Clarify’s test strips use color to indicate if you might have a UTI, the orange urine will make them more difficult to interpret. If you’ve purchased both together, we suggest using Clarify before taking Soothe. 

Uqora Target contains Vitamin C. High intake of Vitamin C may impact the results of Clarify’s UTI test strips by impacting the perceived color. This could lead to a false negative nitrite result. For these reasons, while safe, we do not recommend taking Soothe or Uqora Target before using Clarify.

How does the nitrite test relate to a UTI?

Why is there more than one possible color for a positive UTI test result? Does a darker colored test result mean I have a more severe UTI?
