I wouldn't take a PCR test, just get the antigen test - more likely to test negative and generally cheaper.
The total number of people in the hospital with Covid island wide is 16, and the percentage testing positive hasn't hit double digits in a month or so. The case numbers and hospitalizations in Europe and the US seem to be plateauing so unless there is a drastic change in the next week, there is a strong chance that the testing requirements to enter the country may be dropped with the next update.
