Summary of Plasma and Eluate Panels

Probable antibody: anti-Jka

Antibodies not ruled out: anti-E and anti-K

Self Test

  1. In the exclusion cell panel above, a cell positive for Jka antigens has been set up. What is the rationale for setting up positive controls in selected cell panels?

    Answer

     

  2. Two cells have been tested to exclude the "not ruled out" antibodies. Decide which antibody each cell is meant to exclude and then click on the question mark (?) button to test your choice.

    Answers are displayed by clicking on the ? marks.
