Under Celebrity FAQ, the following definition of Self Testing is given:
Accepted Types of Tests and Results
There are two common types of diagnostic COVID-19 tests and we accept either one:
A molecular test, also called a PCR test or NAAT test
An antigen test, also called a rapid antigen test (RAT)
For sailings from a U.S. port that visit Canada or Bermuda; from Iceland and from the Galapagos, the test must be supervised by a health professional, such as a doctor, pharmacy technician, public health worker, or telehealth representative.
You must receive a valid results document from your test provider that includes provider name, your name, the date the test was taken, type of test, and your negative result. This can be a printed document, email, or telehealth app notification. Handwritten doctor’s notes will not be accepted.
For sailings from U.S. Ports that do NOT visit Canada or Bermuda and for some Europe sailings, any commercially available test, including self-tests, are accepted. In Europe, the exception to this is any sailing visiting Greece, which requires a supervised antigen test.
For sailings in Australia/New Zealand, PCR tests must be taken in a laboratory; Antigen/RAT tests may be self-tests and do not have to be monitored.
So, if I'm understanding above, a Caribbean cruise departing from Florida requires only that I complete a self administered test? How do I show results? Do I keep the display stick result to show them? (That seems a little nuts!)
