In regards to last question I had in regards to small blood in urine I did have a urinary tract infection which was fixed. So could it be serious?

Blood in urine. If you have blood in your urine with no bacterial infection, a cause needs to be found. You could be bleeding from your kidneys, ureters, bladder or urethra. Blood in the urine is abnormal and the cause of it needs to be found. See a urologist for a complete work up for it. Good luck.
