I’m sure the RT-Lamp would be acceptable for arrival back into BVI - it is considered a superior test to a rapid antigen which they do accept. If in doubt, it might be worth your while to get some more rapid antigen in case.

I’ve just completed my first set of tests (Swift Rapid Antigen) for travel tomorrow from YYC-IAH-SJU and onward to Tortola on Saturday…will post if I have any issues.
