Can different Costco locations pull up audiogram

I know Florida Costco can pull up my prescription for hearing aids I purchased in Michigan. I don’t know if they store your audiogram if you didn’t purchase aids but just had the hearing test

It appears that all hearing aid information including audiograms, purchases, returns etc are on a national database.

Yes this is correct. They pulled up my audiogram from 12 years before when I did not purchase hearing aids at that time.
