Hi @info101, welcome to Mayo Clinic Connect. I'd like to bring a few members in like @firstlady, @gaybinator, @vette241,@charmone, @nadia83 and @laylaa who have shared similar experiences. The members of Connect are not medical experts, but can share insight and suggestions from what they did.

I think it is very important to ask these critical questions to you treating physician or their healthcare team. My uncle suffered from cirrohosis of the liver and kidney failure and had ascites of the abdomen. He did have a paracentesis done at home, however, he was on palliative home healthcare. You would need to speak with your physician and insurance to determine if that is something they could provide for you.

It looks as though you have done a lot of research, it is always good to be in the know when it comes to your health. I think to rule out Diffuse Large B Cell Lymphoma (DLBCL) they should have used fluorodeoxyglucose with the PET scan. Did asked your physician why they chose to do it without?
Have you been diagnosed with cirrhosis or kidney disease?
