help with this blood bank problem.
1b. Mr. Brown has been transfused multiple times by the blood bank and he is now going to the operating room for a surgical procedure. A sample is sent to the blood bank for a type and screen and crossmatch for two units of blood. The technologist takes a look at Mr. Brown's historical data to see if he has a history of antibodies or any special instructions He does have a history of anti-Jka from 1996, however his antibody screen is now negative and has been for the past 10 years The ABO/RH results are as follows: Forward Typing Anti-B Reverse Typing Anti-A Anti-D Control A1 CellsB Cells 0 0 0 Antibody Screening results are as follows: Rh KellDuffy KiddLewis MNSs P1 Lutheran LISS R1R1 + 00 0 00 0 0 0000 R1R1 1c. what is the interpretation of his ABO/RH results? 1d. What is the interpretation of his antibody screen?Explanation / Answer
1c) The given Blood is AB+
As the Anti A sera contains antigen of B blood group which will react with Blood group A antibodies and agglutinate and similarity the anti sera B contains antigens A which will coagulate with antibodies of B blood group and here the positive reaction is shown with the A and B anti sera indicating the AB blood group while the anti D which indicates RH factor also given positive result which indicates the AB+ positive blood group
Which can be confirm with the Reverse typing test which contains the antibodies of A and B as the serum of the AB blood group lack antigens AB no agglutination reaction is seen.
1d) Antibody screening test is done to see the presence of the alleles on the same chromosome or different chromosome while both + cells in R1R1 and R2R2 indicate antigen present and 0 represent the absence of antigen and 2+ indicates medium agglutinates with clear background
