Question

Quizplus · Accepted Answer

The most appropriate test for confirming pernicious anemia is a reticulocyte count, which measures the number of immature red blood cells in the bloodstream. In pernicious anemia, the bone marrow fails to produce enough mature red blood cells due to a deficiency in vitamin B12, which is necessary for red blood cell production. This leads to an increase in the number of immature red blood cells. Renin, RBC cholinesterase, and rheumatoid factor are not relevant tests for diagnosing pernicious anemia.
