helloI 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.+12019-08-03T21:27:05Z
hpsbwz@hello Transferrin saturation and TIBC are not synonymous. Transferrin is calculated using total body iron / TIBC.
While the serum iron level continues to increase, the transferrin level decreases. Thus, the amount of transferrin available to bind iron (TIBC) decreases and the amount of transferrin saturated with iron (i.e., percent transferrin saturation) increases.+2019-08-26T18:37:07Z
