 A lot of times having that baseline done is really good to do as well because then you know where you're at early before anything happens and then if something does happen, your doctor can compare those exams and go back and look and say, hey, well, when we did this two years ago, here's what your numbers were and now your numbers are here. I have a concern over this. And so there's a baseline for that doctor to be able to look at and see if there's something that they need to do differently or more testing that needs to be done.
