As I said before, there is a likelihood that some sort of testing might be required before you travel and there’s a lot of talks between the governments, at the moment, before they allow international travel, so that would be either PCR antibody testing. Once someone has landed and they are attending for treatment, ideally I would want you to do PCR before you start treatment and one before the egg collection or the embryo transfer. Because of the cost implications, we are now in discussions with our scientific authorities, and with the scientific board of our hospitals, in order to identify which is the best time to do it. I think, at the moment it seems that the best time to do the PCR testing, is just before the egg collection, results come out in about 12 to 24 hours. Maybe, the day of the trigger might be the ideal time. PCR testing is maybe valuable for asymptomatic patients. If somebody has symptoms, they would definitely have the full check, the antibody screening and the PCR testing, and if there is any suspicion, the treatment will not go ahead.
