Which of the following laboratory findings would be expected when a hemoglobinopathy causes the oxygen dissociation curve to shift to the left?

Question

Quizplus · Accepted Answer

Some amino-acid substitutions forming variant hemoglobins result in high hemoglobin affinity for oxygen and tissue hypoxia.This results in a shift to the left of the oxygen dissociation curve.Tissue hypoxia will cause the kidney to increase erythropoietin production to stimulate increased hemoglobin and red blood cell production.The increased red blood cell production coupled with the red cells already available will result in erythrocytosis.
