Hemolysis ?'s: Blood cells ( "red cells") contain hemoglobin and register as "positive" in urinalysis specimens (under the microscope). Hemolysis is the rupture of the cells , which releases the hemoglobin within, and is detected as "blood in the urine", which is not a normal finding, and suggests the need to find the source of the bleeding.
