what is it called when there is a presence of erythrocytes in the urine?
Red blood cells (RBCs) can be present in your urine, whether you see pink in the toilet bowl or not. Having RBCs in your urine is called hematuria. There are two types of hematuria: Gross hematuria means blood is visible in your urine. Microscopic hematuria involves RBCs that can only be seen under a microscope.
