In healthy men and women, urine does not contain any blood that can be seen with the eye, called "gross blood," nor does it contain red blood cells that can be discovered with the aid of a microscope. The discovery of either gross or microscopic blood in urine is a sure indication of the need to examine and evaluate the patient to discover the cause of this abnormality. The conditions that can lead to either gross or microscopic blood in the urine are many and varied.
