Hemolysis (or haemolysis in British English) is the breakdown of red blood cells. The ability of bacterial colonies to induce hemolysis when grown on blood agar is used to classify certain microorganisms. This is particularly useful in classifying streptococcal species.
Haemolysis (British spelling) is the breakdown of red blood cells. The concentration of many substances is different inside and outside red cells. This answer is only about haemolysis in blood samples. Most biochemical tests on blood use serum, the liquid remaining after blood has clotted or plasma, the liquid in a sample to which anticoagulant had been added. To obtain serum or plasma a blood sample is centrifuged to separate out the cells or clot.
