A member asked:

Is serum total iron a good indicator of how much iron is being absorbed by your body?

A doctor has provided 1 answer

Iron in blood: Total serum iron is a very good indicator of iron absorbed versus iron losses. Thus it reflects a balance. But there are better indicators. The best indicators are: serum iron concentration/total iron binding capacity, which is typically reported. And then this ratio is further reported as "percent iron saturation". Serum ferritin reflects long term iron stores. The % saturation should be >20
