My family member took an antigen test in the DR. Results are supposed to come back to his cell phone - is that normal? Has anyone flown to the US using proof of negative covid test in a cell phone?
Most places that do the antigen test will give you the results within a half hour, both on paper and electronically.
The PCR test can take up to 3 days unless you pay extra for results in 24 hours. Again it will be in both paper and electronic.
All the airlines accept the electronic version.
