Note the "consider rare HFE mutations". I'm not HFE C282Y homozygous, nor are you. My docs decided against the liver biopsy and have been running the full iron panel with the tests you mentioned to monitor me. The ferritin hasn't always been in line with the rest of the iron panel... something to do with a lag in how the iron is being shuffled around.
Also, have you been tested for chlamydia pneumoniae? It feeds on iron, and is another reason to lower your iron.
I wondered that as well, why the ferritin level is not in line with the rest.
Never been tested for chlamydia, I do not really match the symptoms.
