Yes, is okAccording to the US guidelines, "Travelers must have an original printed or electronic negative COVID-19 viral test result (NAAT: RT-PCR, RT-LAMP, TMA, NEAR, HDA, or Antigen: Rapid)". I just signed up for a CDRossi "Test rápido de antígenos", the day before my departure. It appears this test will meet the "Antigen: Rapid" requirements for flying to the US, but can anyone confirm?
