Being a father of a 1 and a half year old boy, I can't even image the pain and sufferings you are going through. And, I can't image me either in your shoe. May Gold show his mercy on Ray and on your family.
However, it seems a little error in your posts.
his red blood count was 7.0. So we rushed to the hospital in town. The RBC dropped to 6.8.
I think those were hemoglobin (Hb), not RBC. Both are not same.
What I know is that AA is diagnosed by doing a Bone marrow study, not CSF study. Was that a CSF collection procedure or bone marrow collection procedure?
