BioVision’s TIBC and Serum Iron Assay Kit measures both Total iron-binding capacity (TIBC) and Serum iron. Those values indicate the requisite iron for transferrin saturation and Serum Iron respectively. In humans, Transferrin is a blood protein that binds and transports iron throughout the body. Iron bound to transferrin and not bound are reflected in the following: 1) Total Iron Binding Capacity, 2) Unbound Iron, 3) Transferrin Saturation Bound Iron, and 4) Free Iron. Those measurements can be used for to detect and monito transferrin saturation and also iron-deficiency anemia and chronic inflammatory diseases.

My % transferrin saturation values are exceeding 100%. Do you know why this could be happening?
Theoretically % transferrin saturation cannot exceed 100%. One possibility could be that the pH of the TIBC developer included in the kit may have changed over time or pipetting volumes of the TIBC developer was not right. Please check the pH of the developer and it should be less than 3.
