Carol, ID Now is not a RT-PCR test but is a molecular test that is a NAAT. All Molecular tests used to identify the Covid-19 virus are NAAT tests. (Nucleic Acid Amplification Test). St Maarten EHAS seems to be using multiple forms of NAAT testing for admission to the island just as they are using multiple forms of specimen samples. Both are in direct contradiction to their published rules and allows for arbitrary interpretation of the published rules.

You are right that they can deny you entry for not following their published rules but it seems that they are liberally accepting many testing samples and testing types for people that are submitting EHAS applications.
