HI, thanks for using healthcare magic
There is no current medical term simon globulin
. It is possible that your father may have misinterpreted what was said.
It would be difficult to say what was the actual blood test
that was done. It may have been a decrease in hemoglobulin from 13 to 11.7.
It would be best to speak to his doctor to find out the exact test and the result.
I hope this helps
