Amykt, thanks for all your answers. I have been trying to get my blood tested for a while now, but because I am on oxygen 24hrs a day, it's hard for me to wait in line for a long time. Tried on line, not tech savvy, but gave me one time to go, & when I went was given a different time. I will keep trying to get it tested. Thanks again for all your help. From buddy Foxy.
