Which of the following genes on chromosome 1 encodes for the 4 common antigen combinations ce, cE, Ce and CE. {Ans: RHCE}A 40 year old man with autoimmune hemolytic anemia due to anti-E has a hemoglobin level of 10.8 g/dL (108 g/L). This patient will most likely be treated with: {Ans: no transfusion -Transfusion should generally be avoided except in cases of life-threatening anemia. Hemoglobin trigger values are usually <7g/dL for most patients. For some patients with certain cardiac conditions, they are higher (less than or equal to 8 g/dL) A hemoglobin of 10.8 g.dL (108 g/L) is not life threatening, especially if the patient is not actively bleeding.}A family has been typed for HLA because 1 of the children needs a stem call donor. Typing results are listed below: father: A1,3B8,35 mother: A2,23;B12,18 child#1: A1,2;B8,12 child#2: A1,23;B8,18 child#3: A3,23;B18,? What is the expected B antigen in child #3? {Ans: B35 -From the first 2 children it can be determined the mom has the haplotypes A2B12 and A23F18. The dad has the haplotypes A1B8 and A3B35. The expected B antigen in child #3 is B35.}An acceptable storage temperature for Red Blood Cells, Frozen is: {Ans: -80
