I went for my nuclear tagged red blood cell test yesterday. The test was to take only about an hour and took nearly six, laying flat on my back in one position. They found more kidney damage from diabetes, but didn't find the source of the blood loss. My hemoglobin has gone back down from a little over 12 to 11, so I'm not gaining any ground yet. They have put a type of leukemia up again as a possibility, though I don't believe it's that. They will give me the full results of the scan back on Tuesday. They took over 425,000 pictures, and then had to take another 4,000 right before I left. They still haven't ruled out several other possibilities like the ulcer in the colon or crohn's disease, I believe they said. If my counts go down to 9, they will re-admit me to the hospital.
