Hemolysis is the bursting and destruction of red blood cells(erythrocytes) which causes the hemoglobin inside the cells to be liberated into the surrounding tissues. The blood cells may become hemolyzed by several different ways. If you had a sample of blood in a blood tube and shook it vigorously this would cause the cells to burst thereby ruining the blood specimen.
Other reasons the erythrocytes may become hemolysized include snake venoms, immune bodies, bacterial toxins, and hypotonic saline solutions.
Hemoglobin lost by hemolysis will turn the urine red, this is called hemoglobinuria. Hemolysis can also be visualised under the microscope.
