We did not have antibody tests but the USVI portal was pretty straight forward and worked well for us. We got our acceptance email about 12 hours after we sent it within the 5 days.

Make sure you send a clear picture or jpeg of your info with clearly legible name and test result and time. We had someone turned down due to illegibility of their result. Hoping they don’t shut things down in the USVI again with some recent spikes I have heard.
