Racing Point say they cannot do any more to protect against coronavirus, despite driver Lance Stroll testing positive after the last Grand Prix.
Stroll was confirmed to have coronavirus after the Eifel GP, where he did not race because he was unwell, but he was not tested at the event.
Team principal Otmar Szafnauer said: "If I thought our process was wrong, I would change it.
"I'm not going to do anything else. There is nothing else to do."
