What is the medical term for blood in the urine?

The medical term for blood in the urine is hematuria. This condition is characterized by the presence of red blood cells in the urine, which can be visible to the naked eye or detected under a microscope. Hematuria can result from various underlying causes, such as urinary tract infections, kidney stones, or other conditions affecting the kidneys or urinary tract.

Hemolysis, on the other hand, refers to the breakdown of red blood cells, leading to the release of hemoglobin into the bloodstream, not specifically related to urine. Hemorrhage describes excessive bleeding due to blood vessel rupture, which is a broader term and does not specifically define blood in urine. Hemoglobin is the protein in red blood cells that carries oxygen; while it is related to blood, it does not denote the presence of blood in urine itself. Thus, hematuria is the most accurate term depicting blood presence in urine.
