Kathy the hemoglobin being at 11 is why you are so tired, was it low anytime In the past (before the IVIG) ? You effectively are running around with 40% less blood (it should be about 15 to 16), that will exhaust anyone, when I was at 11 2 weeks ago I felt like I was made out of mud...

The IVIG antibodies stay in your system about 35 days. In my case it took 30 days for the hemoglobin to start returning to normal. Kathie I would see if you can talk to a hematologist. Hemolysis is so rare few doctors besides a hematologist know what to look for. Why do they suspect a GI bleed? Are there signs or symptoms of that?
