‘Heme’ means blood and ‘uria’ means urine.

Hematuria is the medical term for blood in urine. If you ever notice that your urine is tea-colored, purplish, brownish, pink or red, see your doctor immediately! Unfortunately, this blood is not always visible to the naked eye and must be found through a routine urine test. When examining urine for blood, we pay close attention to the shape of the red blood cells under a microscope. This usually clues us into the cause.
