On December 3, 2021, the US government announced that arriving air travellers must produce the results of a negative COVID-19 test taken no more than 24 hours before their departure. As of Monday, December 6, Avalon’s clients will be able to book appointments for rapid antigen testing 7 days a week HERE. Because of the high number of telephone calls, clients who need to rebook their rapid antigen tests should email firstname.lastname@example.org. Emails will be answered between 8:30 am and 5 pm, Monday through Friday. Avalon Laboratories continues to offer RT-PCR testing for COVID-19 Monday through Friday.
