A 70 lb. (32.2 Kilogram) child needs an autologous unit drawn.  How much anticoagulant must be removed from the bag before collection? (450 mL collection bag used)

At the end of antiglobulin phase, coombs control cells (check cells) are added to the negative tests. If agglutination occurs after the addition of check cells, this means:

If you are antigen typing the patient for the s antigen because you have identified that the patient has Anti-s, what antigen typing result are you expecting that would support your antibody identification?

Determine the blood type and patient secretor status from the following information if possible: Saliva + anti-A + a cells = agglutination Saliva + anti-B + b cells = agglutination Saliva + anti-H + o cells =agglutination

When performing an Antibody Screen or an Antibody ID Panel, during the AHG phase why are the rbcs in the tubes washed 3 times before adding AHG reagent?

The antibody that may be a weak level in the patient’s serum and give a false negative antibody screen and is a cause of delayed hemolytic transfusion reactions would most likely be:

A mother who has the blood type O and a father who has the blood type A could have children with the following genotypes: (do not include the subgroups for this question)

The antigenic determinant that both C and D have is:

A patient has the phenotype 0, DCce.  If transfused with blood from six random group O Rh positive donors, the patient could theoretically produce which of the following antibodies:

Which antibody type will readily cross the placenta?
