A member asked:

Urinated about 30 minutes before taking an aptima combo2 urine test for stds, also urinated into the cup midstream. could that change the results?

A doctor has provided 1 answer

First morning urine : It is most accurate to get the first urine of the morning for the most accurate results. This could possibly change results otherwise if urine is dilute/"watered down".

I have off and on burning sensation a few seconds at the end and a few seconds after urinating. It is not all the time. Urine test result to check for UTI is negative and I have almost no risk of STD. What else could be causing it?
