My brother is finishing up his tests...so far he's gotten alot of x-rays, CT scans, bone density (which is just another x-ray), alot blood work, a 6 minute walk where he just had to wear his O2, have someone take his pulse ox every 60 seconds and make sure that he walked over 600 ft. in that amount of time (he did 848 ft.), and a full pulmonary function test. He doesnt have to get the heart cath, or a colonoscopy beacuse he is too young (21) and has never had any problems with anything else but his lungs and pancreas. The last test he has to do is his PFT, but our doctor is waiting till he feels better to do it. He has been in the hospital now since October 4 and doenst look like he will coming home soon, sadly.
