Does Uristat Ultra affect the urine sample for a UTI?

Don’t know where else to ask this but the nurse just gave me a hard time for taking Uristat Ultra coming into urgent care for a UTI bcus it might not test positive .

She said I know it hurts but next time just come in with pain and all. Don’t take a single thing.

I’m confused because I always have UTI’s and have always tested positive for a UTI even while taking Uristat Ultra with super bright orange samples.

We were trying to conceive bcus my opk came out positive . Woke up with a UTI and recognized it so I came to get antibiotics before it gets worse. Am I going to have to retest while in pain ?
