Not to that level, but the 3 day ‘sputum’ test is very common. It seems she may require a little more?
In our case, she has to do the 3 day test, just finished. Now it’s an 8 week wait. As to extra costs, my understanding is most is covered by the initial payment for the St Luke’s medical check. Again, your situation could be different.
Seems to me, best to keep St Luke’s involved in some fashion, since they are the ones you have to satisfy. The medical check cost is supposed to increase on Aug 19th or so. Of course, hotel rooms, flights, food, $$ starts to add up.
