Last September when I came back from France, I took an antigen test at a pharmacy, I paid 25 euros, the price is fixed in labs and pharmacies, and my Us insurance reimbursed me after seeing the paperwork. The cost did not change, everything related to health is very regulated specially the cost either for citizens or foreigners who do not have the health coverage. To give you an idea, once, I had a bicycle accident, damaged my hand, stayed in a hospital 24h in a single room, had an hour and 30mm surgery the bill that I had to pay out of pocket was around $2000. Living in the Us I am not eligible for the French coverage, if it god forbids, had happened to you you would have had to pay the same.
