A registered nurse will use a plastic swab to take a sample from the throat and 1.5 to 2 cm into the nostril, which is far less invasive than the 4cm required for nasopharyngeal swabs. Results will be ready within 24 to 48 hours of testing, and can be ready on the same day with express service.

For corporate partners in Hong Kong, Evercare helps companies test their employees before they return to the office. Under this scheme, registered nurses visit the workplace to administer testing, reducing employees' travel time, and raising work productivity. As Hong Kong prepares for a "health code" and "travel bubble" it opens up travel with mainland China, Macau, and Singapore, and thus the test is suitable for all cross-border travel.
