Dad had all the tests today and they didn't find anything wrong. Not the heart and no blood clot. They did find that he was anemic again and are giving him 2 units of blood tonight. The kidney doctor said he had dropped in kidney function from 28% that he had been holding to 20% now. If they insert the dye to check the heart, veins and valves- it will destroy the remaining kidney function and he would have to do dialysis the rest of his life.
They are going to do a sleep apnea study.
Thanks for your prayers.
