As I stated, the nurse did not offer the saline chaser, but I was so anxious to get that pipe needle out of my arm, I don't think I would have sat still for the chaser. Also, although the goal was to get 450 in blood, she barely was able to get 400 before I called uncle! And it took forever to get to that point. I can remember when I donated regularly that the bag would fill quicker than the phlebotomist could turn around. So it would appear that things are progressing. Hoping to hear from Mayo Clinic soon.
