I'm a 31 year old male and although I don't think I've ever clearly seen blood in my urine, I'm still worried. I sometimes provoke thoughts saying I have (I have OCD). I provided a urine sample in January and it was fine. I've provided another urine sample and am waiting for the results. By urine sample I mean I urinated into a bottle and gave it to reception at my GP practice. My urine was orange once or twice, but it went away. I was just hoping for some reassurance. I was wondering whether urine cultures are reliable and am I ok even if there is no infection?
