Guys: White/Yellowish Cloudy Urine Problem?

You need to collect the sample in a sterile tube so rinsing it with water won't do. I advise you to go back and get another container. To obtain your cloudy urine, maybe it would be best to urinate in the morning, that's when your urine is the most concentrated. Hope this helps but you could always ring the doctor's surgery or the lab to confirm this.
