I'm thinking of ordering this test so I don't have to schlep off to town to have the blood taken. Will the ferritin result tell me if I need iron supplements? (Tbh it's something I've never understood, why you need a test for iron and ferritin.)
Yes, the ferritin test shows stored iron and is a good indicator of whether u need supps, though it may be raised if you have current inflammation. Go for it.
