That's a good question. I think that the test kits will probably give
immediate reading for the free iron, and an indication of the total if
for a long time. Trying to measure low concentrations of something like
that will not be an easy task, particularly with simple test kit

I think what most people (including myself) do is to go for "just
detectable" iron, and not worry about the actual amount. Biological
are pretty tolerant of variations in concentrations of most elements,
one does have to be concerned about overdosing.
I hope that is of some help.
