Question

Quizplus · Accepted Answer

Monitoring 51Cr labeled RBCs is the most reliable method to measure RBC survival as it tracks the decay of the radioactive label in the RBCs over time. Conjugated bilirubin levels and urine hemoglobin can indicate hemolysis but do not give a direct measure of RBC survival. Reticulocyte count can indicate erythropoiesis but is not a direct measure of RBC survival.
