Question
Study Questions: 1. List the blood groups that the following patients can receive if they needed a Red Cell transfusion AB 2. What antibody does a type "A" person have in their serum? 3. What antibody(s) does a group O person have in their serum? 4. In this test, why do the sample red cells require dilution prior to testing? 5. Why are antibodies to the ABO group so dangerous? 6. Why are ABO blood group antibodies considered "cross-reactive"? 7. What is meant by forward typing and reverse typing? 8. Rh (D) antibodies are formed by antigenic stimulation fromor 9. Why is an adult Rh incompatible transfusion significantly less fatal than an AB0 incompatible transfusion? 10. What can happen if we don't dilute the red blood cells for forward typing?Explanation / Answer
1 Blood groups that following patient can receive :
A- A , O blood group
B - B,O blood group
AB- A,B,AB,O blood group
O- O blood group
Ans 2 Anti B - antibody is present in the serum
Ans 3 Anti A and Anti B antibodies is present in o blood group serum.
Ans 4 Red cells require dilution to prevent blood from clumping and to detect a particular antigens and antibodies.
Ans 5 ABO blood group are so dangerous because it can cause agglutination in recipient blood and various transfusion reactions can occur result in anaemia ,RBC lysis.
Ans 6 Cross reactivity occurs when the blood group of a person antigen reacts with the different antibodies in a recipients blood thus refer ABO as a cross reactivity.
Ans 7 Forward typing - the blood serum is mixed with the anti serums .A blood is mixed with anti A- serum conating antibodies.
Reverse typing - In reverse typing the blood of two different serum are mixed with each other.
Ans 8 Rh D antibodies stimulation from red blood cells or by Rh antibodies.
Ans 9 Rh incompatibily factors are less fatal than ABO because there is no transfusion reactions are observed in Rh incompatibility .
