Therefore, we reapplied a “corrected Mentzer index” and included infants exhibiting “microcytic hypochromic anemia” using following cutoff indices: HGB less than 11 g/dl (normal values 11–14.1 g/dl), MCV less than 72 fl (normal values 72–84 fl), MCH less than 25 (normal values 25–29 pg), and MCHC less than 32 (32–36 g/dl). Here, CYGB is linked to anemia.
