For CD34 and CD38, AUC was moderately high in the tested model, anemic vs. non-anemic (AUC = 0.600, sensitivity 76.8%, specificity 50.0% for CD34, and AUC = 0.657, sensitivity 76.8%, specificity 57.8% for CD38), which indicates their moderate diagnostic utility in patients with anemia. This evidence concerns the gene CD38 and anemia (phenotype).
