@mariec260 hi marie! i have basic insurance and had to pay for most of the test I wanted and spent alot of money of my own as my doctors and gastro were not helpful at all or wanted to test the things I wanted. My wbc have been going down and ferritin going up and they said nothing although along with other abnormal markers that they dont seem to care about especially the brainfog. I recently got into Mayo and hope to find an answer as it seems its all gut related.
