I am assuming you are asking about a test in order to re-enter the USVI . . . ??

The clinics on JVD and VG will do PCR Testing (they will take the sample). The hospital in Road Town does PCR sampling and they house the lab that processes all(? I think) the PCR tests in the BVI. Several other clinics on Tortola will take samples for PCR testing (B&F, Eureka, MD Link, Penn, PicSmith). The only one that I personally know of that is doing rapid tests is The Wellness Center at Pier Park in Road Town. There are some concierge services but I am not aware of the details of those.
