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

In brief: 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".
