BLOOD IN URINE (HEMATURIA)
Hematuria is the clinical name for having blood in your urine. Seeing blood in your urine can be alarming. While in many instances the cause is harmless, blood in urine (hematuria) can indicate a serious disorder.
Hematuria can be either gross (visible) or microscopic (blood cells only visible through a microscope). Gross hematuria can vary widely in appearance, from light pink to deep red with clots. Although the amount of blood in the urine may be different, the types of conditions that can cause the problem are the same, and require the same kind of workup or evaluation.
People with gross hematuria will visit their doctor with this as a primary complaint. People who have microscopic hematuria, on the other hand, will be unaware of a problem and their condition will most commonly be detected as part of a periodic checkup by a primary-care physician.
