What does a blood clot in urine look like?
The presence of blood within your urine can be concerning. While the reason is often innocuous, blood in the urine (hematuria) can signify a dangerous condition.
Gross hematuria refers to visible blood. Whenever your doctor checks your urine, he or she will find microscopic hematuria (urine blood visible only under a microscope). In any case, the cause of the bleeding must be determined.
