Frequently asked questions
Transferrin saturation: What does this calculator compute?
Calculates transferrin saturation from serum iron and total iron-binding capacity or transferrin (TIBC = transferrin × 1.41 or × 25.1 in SI) and compares it with the pediatric CALIPER reference intervals; in children, < 16 % suggests iron deficiency only together with anemia and low MCV.
