Have you discussed this [low RBC and low copper] with your doctor. I've not heard anything here about low copper, but that doesn't mean it wasn't discussed as I may have missed it.
I think it would be wise to make sure your copper is low before worrying about it.

I've never been tested for copper levels. It's an unusual blood test to order. The doctor must have had an idea that low copper was involved in order to think to order the test. That's why I say he must be a good doctor.
I was reading a bit about copper and zinc. Mainly because zinc is supposed to help control the various Herpes viruses. So, apparently there is an absorption trade off between the two. That is, if one over consumes zinc supplements then a low copper can result. And vice versa. Over consuming copper can result in low zinc.
Meredith, have you asked? Does your doctor test all ITP patients for copper, or ?
