High ferritin low serum iron

Hello :)

Last year I had blood taken and my ferritin was 86, at the middle of the reference range (15-150)

However my serum iron was 65, in the low part of the range (50-170)

Has anyone experienced high ferritin but low iron?

I just had more bloods done and ferritin was 129. There was no serum iron taken but I’m thinking to ask my GP to test this in case the same is the case - good ferritin but low iron.

Can’t find much info about this online.. anyone shed any light? :)

Ferritin can be raised due to inflammation so in that case you could have high ferritin and low iron. Testing the inflammation markers - typically CRP - at the same time is helpful, if CRP is high then it's likely ferritin is high due to inflammation or infection.

I am also suspicious about my relatively high ferritin. I am planning to test my transferrin saturation next time I get blood work done.

Medichecks do a home iron test which is the full iron panel - serum iron, saturation %, total iron binding capacity and ferritin. It's £39 but we have 10% discount code here:

Thanks, my CRP was <0.3, and I think this is ok? I have been inflamed in the past and I don’t feel it now
