Question

Quizplus · Accepted Answer

Monitoring ⁵¹Cr labeled RBCs is the best option as it involves labeling the RBCs with a radioactive isotope and tracking their survival over time using nuclear medicine imaging techniques. This is a direct way to measure RBC survival and is considered the gold standard method. The other options, such as measuring conjugated bilirubin, urine hemoglobin, or reticulocyte count, can provide indirect information about RBC survival but are not as precise or accurate.
