The hemolysis test is important in the blood bank when blood group “O” contains anti-A and anti-B antibodies which may be Hemolysin. Therefore hemolysis test procedure is the key test for hemolysis identification.
Â
When such blood group has a high titer of such antibodies are transfused in a person having blood group A, or blood group B or blood group AB. It will cause hemolysis of receiver blood RBC.
Such an “O-positive” group is known as UNIVERSAL DANGEROUS DONOR. This blood must be used only for O-group.
Following steps performed during hemolysis test procedure.
If there is hemolysis in test tube A or B. It means blood is not safe for transfusion. It can ONLY donate to the O-group recipient.Â
When there is a Positive hemolysis test result, it means, blood is not safe for that receiver. It will cause hemolysis of receiver RBC.Â
Note: This O-group can be transfused in O-blood group members only.
It is an important test for the early identification of UNIVERSAL DANGEROUS DONORÂ which causes hemolysis of receiver red blood cells.
O-blood group is known as UNIVERSAL DANGEROUS DONOR because sometimes it has LYSINE antibody which causes lysis of receiver red blood cells.Â
