My brother in law 51y and generally very healthy has just had his blood work done. His ferritin level is 456 while the upper limit of the norm for men is 400. He wasn't vaccinted himself but has spent quite some time with recently vaccinated colleagues and family members. I think it was Nemo raising awareness of the increased ferritin level as a marker of vascular inflamation. Now we see it also in unvaccinated people (although to be 100% clear I don't know what his previous values were). The question is: will it go down by itself after a while or should he do somethig about it?
