Microscopic means that something is so tiny that it cannot be seen with a naked eye. You can see it only with a microscope. If you have microscopic hematuria, it means that you have red blood cells in your urine, but you can’t see the blood when you urinate with your eyes.
Hematuria is a condition of red blood cells in the urine. This causes a change in the color of the urine to red, pink or cola. But, sometimes the color of urine remains same. Red blood cells in the urine can come from a variety of reasons indicative of different diseases.
