Harpoon makes a point. You did mention some nausea. It would likely be just an outpatient blood test. Most of us totally understand how you have come to dislike hospitals so intensely.
We're all greatly concerned for you, Ross. In some way, however this goes, we will all be along with you. I can't talk about stubborn, because I'm the same way, but just be sure you're tempering it with your own good judgement, and not just your completely understandable resentment of the situation.
Very best wishes,
