I thought you were hoping having a good ale or beer might fix the ferritin issue...worth a try maybe? ;-)
I have a mild ferritin deficiency and I take ferrograd c as recommended by my doc. I can't comment on the numbers as I'm sure different labs use different scales...is there any guidance info next to it? Mine usually appears for example as blah blah level is 26 then recommended level is in brackets like (>30) That should help. Any issues discuss with your doc.
There was also discussion on here recently about what to let your Rheumy know....well.....EVERYTHING is the answer! You can also ask your doc to send results through to your Rheumy and vice versa....even if its something they don't necessarily need to know what's the worst that can happen, they'll look at it and file it away....but at least it's there on file.
Good idea with the binder, I know I should be more organised like that!
