What is it?

Hematuria is the presence of red blood cells (RBCs) in urine. It can appear as visible blood (gross hematuria) or be detected only under a microscope (microscopic hematuria). The amount and persistence of blood in the urine help determine whether it originates from the kidneys, bladder, or urinary tract.

Why does it matter?

While minor and temporary hematuria can result from exercise or minor irritation, persistent red blood cells in urine can signal infection, kidney stones, trauma, or structural abnormalities. It can also be an early warning sign of more serious issues like bladder, kidney, or prostate cancer.


Detecting hematuria early prompts further testing such as imaging, urine microscopy, or cystoscopy to identify and treat the underlying cause before complications develop.
