However, most patients with multifactorial anemia after one week were normocytic and normochromic (83.9%) with elevated median ferritin levels of 795 μg/L (440–1419 μg/L), CRP levels of 4.05 mg/dL (1.36–8.02 mg/dL) and IL-6 levels of 19.4 ng/L (7.5–60.6 ng/L), as well as decreased transferrin levels of 131 mg/dL (103–162 mg/dL), again, all hallmarks of AI. This evidence concerns the gene IL6 and anemia.
