bdeeley,

The difference between a BianaxNOW done at an official test site and one done at home is at the test site, someone trained to perform the nasal swab takes the sample and performs the test process. At home, the person
testing themselves takes the nasal swab.

I agree that it is a very small difference, but evidently enough difference that it will not be accepted by SXM's EHAS review. The application will be denied.

On the official EHAS link it clearly states:
"Results from home covid-19 collection test kits will also not be accepted."

I don't like it any more than you.... but currently the BianaxNow Home test will not meet the requirements.
