Please confirm with your airline and destination country any requirements for pre-travel testing times. For our virtual tests, eligibility rules for advance purchase have been set based on turnaround times for shipping to and from your testing location as well as lab processing time. A minimum 7 day advance purchase is required for virtual PCR pre-travel tests. Additional details of eligibility will be provided upon entering flight details at time of booking. This ensures that you will have enough time to receive your kit, complete your virtual observation and return your sample to the lab for processing in advance of your flight. Our appointment times are set to ensure your sample is collected within 72 hours of your flight departure time.
