Hello @yakutatcharters, Welcome to Connect. I know it has to be difficult trying to get help for your brother when living in a remote part of the country. I was not familiar with molecular testing but I did find a lab that may be close enough to help with testing for you or possibly provide a contact for you to get the needed tests.
