i have a lot of ferritin and Hct levels on file. personally i have never bothered with Hct as an indicator.
however, in review, my doc has always ordered it when she orders a ferritin test, and sometimes on its own.
anyway, i clicked through onto that link and please, rest assured i am NOWHERE near iron overload levels, not even remotely close.
i have an acquaintance in the same building as me who has hemochromatosis and needs regular phlebotomies or his ferritin levels get up over 400.
my lab's guide to ferritin levels (in ug/L)
<18 probably iron deficient
18-40 possibly deficient
41-100 probably not deficient
101-300 not iron deficient
>300 possible iron overload
jimmyleg's iron timeline:
starting point, 2001. jimmylegs knows nothing about anything at this point in her life, and only has even this basic data because she told her doc she was vegan.
jan 2001
ferritin - 27 ug/L - possibly deficient
Hct - .41 (range 0.33 - 0.450)
may 2002
hct - .38
dec 2005
ferritin - 36 ug/L - possibly deficient
Hct - .40
jan 2006
Hct - .398
jan 2006
DX: MS. jimmylegs starts reading like crazy, starts eating animal products again, and accepts that she had better start taking supplements to correct 15 years nutrient drain via masked starvation
nov 2007
ferritin - 82 ug/L - probably not deficient
Hct - .394
apr 2009
ferritin - 90 ug/L - probably not deficient
Hct - .42
i have done other tests of other types more recently but i don't have the copies in my file yet. i have still never cracked 100 ug/L for ferritin, to be categorized as 'not deficient'.
i would say even with supplements i'm still on the low end of the ref range, for certain.
from your link (my emphasis added):
Quote:
The safe level of stored iron, called ferritin, was previously 500; after Sullivan's 1992 study, most people accept 120 as normal and 200 as being significantly toxic.
