As restrictions on international travel are gradually being lifted, many destination countries require a medical certificate showing proof of a negative test result for Covid-19, either to gain entry or to avoid the need to quarantine. Even in cases where the destination country does not require proof of a negative result, knowing you are coronavirus free before travelling to a foreign country can give you extra peace of mind. Please check with your airline or destination country to determine how soon before departure the test has to be taken and processed by the lab.
