Which is the most appropriate reflex test?

Quizplus · Accepted Answer

The patient's results indicate a severe microcytic, hypochromic anemia, which is likely due to a decreased production of red blood cells. To confirm this, a reticulocyte count would be the most appropriate reflex test, as it measures the percentage of reticulocytes (immature red blood cells) in the blood, which reflects the bone marrow's ability to produce new red blood cells. Hemoglobin electrophoresis, osmotic fragility test, and erythropoietin assay are not indicated based on the patient's results.
