Tomorrow we head to Chicago (again) for more testing and to meet up with a new doctor. Shelby will have PFT's (pulmonary function testing) and see a Pulmonologist. This was all planned before the HPS was discovered, but an exercise 02 saturation test will now be done because of the new diagnosis. I will update more after her appointment. Please pray that nothing "new" is discovered and that her oxygen saturation level is GREAT. Thanks!
