My son's father's adoption records are sealed and he is no loner in the picture. I can't get his adoption records opened myself. Is there any way to get my son's blood tested in order to prove native american ancestry?

Do you know which tribe or region you believe the Indian Nation to be from. Each tribe has it's own registration rules so I would start with the BIA or ask the registration dept of the tribe you are inquiring about his heritage if they know of DNA testing. I know that it isn't acceptable in many tribes, however, I'm not an expert either. Just from experience our roll#'s were dependent on if one of our ancestors had a DAWES ROLL number, if they were full blooded and weren't on the DAWES ROLL, one couldn't be a member of that federally recognized tribe. Our Grandmother had a roll number, so I was fortunate, many are not.

All I know is that he was born in Texas, near Arizona somewhere in the northeast region in 1979. His adoptive parents tried to get the mom to give info on herself and the father but she refused. Do you know what tribe resides there?

Huh, I need to look on my son's birth certificate. I obviously am not remembering this right.

Yes, the Human Genome Project has collected sample alleles from all races. A DNA profile for racial origins can therefor4e certainly show one's ancestry. I would suggest that you contact the Project for details of studies in your area.
