Hi there ~
You need to consult a doctor for the elevated RBC
level, iron saturation and ferritin levels as you might have a condition separate from Gilbert syndrome
. I believe you should have elevated bilirubin
levels in Gilbert syndrome. If you have stopped using vitamin C
it is another reason you should consult your doctor who prescribed the medication in the first place. You might also need to donate blood on purpose while they run tests to find out the reason for your increased blood levels. I hope this helps.
Take care and have a lovely day!
