This is what I got from the InspireDiagnostics.com:
The earliest you can order is 15 days prior to your cruise date. The system will not allow you to place an order until your vaccination cards are uploaded and approved. If you decide to have the test sent to your hotel, please check with your hotel first for their policy on accepting packages for guests.
Tests accepted for the Pre-Cruise testing are PCR, NAAT, and Antigen. An at-home antigen, PCR, or NAAT is only permitted for pre-arrival embarkation testing if it is observed by a medical professional (telehealth) and the guest can produce an official lab report.
Your options for Pre-Cruise testing are:
• Schedule an Inspire onsite appointment at a location near the port. This can be done through your Safe Passage account. Cost for this is: US locations - Antigen-$46.58(USD) and PCR-$98.33 (USD) Canada locations – Antigen - $78.25(USD) and PCR $139.10(USD)
• Order the Inspire home At-Home Antigen test kit. Once ordered, an email will be sent with a link to schedule your telehealth appointment 1-2 days prior to your cruise. This test can be done from any location with a laptop, computer, or smartphone that has a camera. You can order this in Safe Passage within 15 days before your cruise. The cost is $46.58. (USD) This is shipped via UPS.
The coordination times (15-days before the cruise to order -plus shipping time???) are too tight for us. I'm going with eMed.
