Carbon Health is able to meet specific guidelines and provide the necessary forms for international travel. We also guarantee test results turnaround time of 3 hours same day or by 2pm the next day. Turnaround times and types of tests available vary by location. It is up to each patient to ensure our testing results and turnaround times are valid for international travel clearance and that any paperwork is handled separately. We recommend patients inquire directly with the airline or regulatory authorities of their travel destinations 7-10 days prior to their departure date. Many countries require testing 48 to 72 hours prior to departure.
