I’m kinda excited... My Dr approved me for a Protine/INR Machine! I test once a week. This is what I feel good about. But..... does anyone have any pointers? I have read in a Medical Guide That APS Patients should NOT use an at home Machine, it really didn’t say why? I plan on going to my Dr EVERY Month to be tested there but this is going to be a Heaven sent devise for me to be able to test weekly as well. My Dr Office is pretty far from my home, so this will help to make that decision whether I need to go in for a visit. Plus I will be in sync with my Drs on my weekly results as well. I’m very responsible & take my Illness very very serious!!! What are the pros & Cons of doing at home weekly testing???
