Yeah, you can use the Bibax test but it HAS to be proctored (so you do a video chat with them and they verify the test). The airline will need to see the test result, provider name, etc, so a regular at home test isn't good enough. In reality it is the exact same test. For travel though you need the proctoring. Do a Google search for rapid home test for travel. They are 69.99 for 2 and qualify for return to the US.
