문제
A newborn is anemic and jaundiced. The maternal antibody screen contains anti-K, and the newborn's DAT is positive. Which finding best links the maternal antibody to the newborn's red cells?
1A negative maternal autocontrol alone
2A normal maternal platelet count
3Recovery of anti-K from an eluate prepared from the newborn's red cells✓ 정답
4An increased maternal fibrinogen
해설
Elution removes antibody bound to the newborn's red cells. Demonstrating the same specificity in the eluate as in maternal plasma supports antibody-mediated hemolytic disease.
