At what point is the fish test done? Newly diagnosed watch and wait and oncologist has not done one. Do other numbers determine when this test is done? Had my first follow up appointment this week. Numbers only slightly worse than two months ago. Cannot break the cycle of upper respiratory infections so he is working to try and get insurance to approve immunoglobulin therapy. He said my antibodies are low enough that hopefully they will approve. Says it is easier to get private insurance to approve than Medicare (US). Would be grateful for any insights. This group has been invaluable for to me in my short journey. I thank you all!!!
