Hi,
I'm from the UK and my ferritin is currently 477 (blood test taken on 26/04/2010). My ferritin dropped as low as 197 but that was my fault as I didn't check my ferritin for months.
I am on combined treatment of Desferal and Deferiprone, but my treatment has been put on hold as my ferritin is too low so once it goes above 500 I am on a bit of a holiday.
I have felt both sides of the ladder, very high ferritin and very low ferritin now. In 2003 I developed iron overload in the heart and liver which caused me to go into cardiac failure. I don't know how I managed to survive it but I did and then was on the 24 hour a day desferal infusion for 5 years and only then my ferritin came down to around 1000.
My advice to you is don't let your ferritin go above 2000 if you can as the complications that come with it put a complete halt on your life and you never feel the same after.
