Patient RBCs tested with commercially prepared Patient plasma tested with commercially prepared Anti-A Anti-B A1 cells B cells 4+ 0 1+ 4+   Analyze and interpret the blood group typing results above for a 36-yr. old male patient. The test has been repeated tat the same results were obtained.  Identify this as a forward or reverse type discrepancy.  Next, indicate the most probable cause for the discrepancy, assuming there are not any technical or clerical errors, and the patient has not been recently transfused.  How would you attempt to resolve this discrepancy to confirm an ABO blood group type? Be specific in you answer.  Provide all test that would be performed as well as the expected results if your initial theory was correct.
