Normal Iron Ferritin Counts Blood Tests, What Does Low % Iron Saturation Indicate?

Blood tests, what does low % iron saturation indicate? - normal iron ferritin counts

Hello to all.

I received the results of my blood tests some time ago. The iron profile shows the following:

Iron Total: NORMAL
UIBC: NORMAL
TIBC: NORMAL
Ferritin: NORMAL
% Saturation: low (15%, in which the range should be between 20 and 50%)

The doctor prescribed me Palafico for a few months.
I know I am low in iron, my question is, as the title suggests, what is the% saturation is low for me, for example, it fell to 5%? What happened? How is it different from other values. I looked on Wikipedia and it is not clear to explain to others, but not this particular value.

Thanks for the help.
