i know this question has been answered, but i am just about ready to make appointemts and want to be 100% certain i got it right...guess i have a touch of OCD.
If your question is whether it is acceptable for entry into SXM, the answer is yes, if done at Walgreens. Around here, that test isn't available anywhere, but I guess it is available where you are. The time period on it is 48 hours.
We used ID NOW from Walgreens--it is considered a PCR test so can be done 72 hrs. prior to departure, unless anything has changed. We were not charged and got the results back within 2-3 hours. Don't have any info on binax NOW as we didn't use it.
