On another forum, I saw postings from individuals taking HU for ET, who have seen high RDW values in their blood work.

When they asked their doctors about it, they were told it that may be a side effect of HU, and not a cause for concern -- but maybe an indication that taking a multivitamin could be helpful.

Of course, only your own doctor can evaluate what the higher RDW count may mean for you.

I hope you won't have to wait a couple more months before having your question answered. It's impossible not to worry when we get "off" numbers.

You've been through a lot! To better days ahead.
