Glad to be able to help. This is a problem I see alot. Most frequently in my own household. You can re-check the urine at any time. However to make sure it has really cleared you need to wait 12-14 days after the last treatment. That is because prior to this there can still be enough medicine in your system to cause a false negative. However if you test sooner ( as in as soon as the 10 days of drugs have past) and get a positive then you know you still have an infection.
The final answer being, if you think you still have a UTI then recheck after the meds. If it comes back positive then you are right. If you just want to check to make sure it is gone you need to wait 12 days to make sure you are getting accurate results.
