I am trying to understand the logic behind iron blood tests. And need some help.
My results are:
Serum iron level: 16 ( 9 - 30 umol/L)
Serum transferrin: 28 ( 25 - 45 umol/L)
Transferrin saturation index: 0.29 (0.0 - 0.45)
Ferritine: 63 (15 - 150 ug/L)
I've read multiple times that to find out Transferrin saturation I need to divide iron by transferrin. If I do it I get following:
That looks like my transferrin saturation is higher than the upper range. Why the lab gives a different number then? And how to interpret it with the rest of the tests?
I would say :
Iron is only 33% along the range instead of 55 to 70%, this is low.
Serum transferrin is 15% of the way through the range, which is probably also low.
Ferritin has room to get higher.
And Transferrin saturation is a riddle for now.
My naturopath does not seem to see any problem in this picture. Would it be necessary to address low iron by supplementing, or something in this test is not correct?
