What should a good ferratin level be new blood results ?

hi could someone please tell me what a good ferratin level should be? iv just had my blood tests back endo iv been on levo for 3 months now which and my free t4 has dropped to 9.5 again from 11.3 its like banging your head against a wall at the moment i decreased my dose from 100mg of levothyroxint to 75mg the past month and think this could be why levels are down so gone back upto 100mg so i think im sorted with that but the ferratin is 28 ug/L range 11-200 i think this looks low? but here i am again as there in range i know im going to struggle with the nhs doctors can anybody give me some good advice and understanding of these ferratin levels any help really would be fantastic with my battle of getting well again

Hi Sara

Looks low to me! Why bother having ranges if they are going to be ignored...!? *sigh*

Why did you reduce your levo? Have you got the ranges for the tests?

When did you take your levo before the tests and what time of day were they?

Do you take your levo with water only, at least an hour before food and with a 4 hour gap between iron and/or calcium supplements?

This information will help people to better offer informed support.




this may help

level should be 70-90
