Increased intestinal iron absorption
I think you made one slight mistake.
TIBC = total iron binding capacity. It is synonymous with "transferrin saturation". This patient has increased transferrin saturation aka increased TIBC.
The transferrin molecules are saturated -- it is incorrect to say "as transferrin saturation increases, there is less circulating carrier molecules."
It is more correct to say that the amount of free (unbound) transferrin is decreased.
