If red blood cells in urine sample are higher then normal [68.20 ] ; remaining urine test was normal; does this mean I had UTI or some thing eles?

Maybe not UTI. red cells in the urine , can be from trauma, kidney disease or disease of the urinary tract. They do not often appear in UTIs without White blood cells. I suggest that you have the test repeated and discuss the results with your physician. The most common cause is contamination of the urine with menstrual blood.
