More about CFT

No:1. The terminal components of the complement damage the cell membranes in the presence of a specific antibody, which fixes complement to the cell surface.
No:2. In the CFT, Reb Blood Cells ( erythrocytes) are used as the target cell, as complement induced damage of the cell membrane can be measured as an increase in free hemoglobin.
No:3. When specific antibodies in response to an infectious agent are present in the blood serum, a complement in the system is bound to the Ag-Ab complex, leaving no residual complement to react with antibodies that belong to the erythrocytes, so hemolysis will not occur.
No:4. So, the absence of hemolysis confirms the presence of specific antibodies in the blood serum.
No:5. If hemolysis occurs, it means, the specific antibody is not present in the blood serum.
