Kim has trouble with the hematocrit test, too. One thing she learned is that spinach, reputed to be high in iron, suffers from having high oxalates, which interfere with iron absorption.
Also, you should drink some water to keep the blood flowing, but too much will also lower the hematocrit.
My last time at the Red Cross was tough because my blood flowed at a glacial pace. The nurse kept fiddling with the needle and ended up jabbing the inside of my arm rather badly at some point. We managed to finish eventually, but my arm was sore for weeks.
