The Government today announced that the self-paid serology antibody testing service for eligible arrivals will be rolled out at the Hong Kong International Airport from August 18.

The antibody testing service is provided by private testing institutions.

The test result will be available in about two days, if it is positive, the Department of Health will contact the relevant persons through their designated quarantine hotels to shorten their compulsory quarantine period to seven days.

The cost of the remaining seven nights of room reservation can be refunded.

For people who have stayed in medium-risk groups of places on the day of arrival at Hong Kong or during the 14 days before that day, if they are fully vaccinated, have obtained a negative nucleic acid test result upon arrival at Hong Kong and possess a positive result proof of a recognised serology antibody test, their compulsory quarantine period in designated quarantine hotels can be adjusted to seven days, followed by a seven-day self-monitoring period.

They have to undergo two nucleic acid tests during the seven-day compulsory quarantine period, and undergo compulsory testing on the ninth, 12th, 16th and 19th days of arrival at Hong Kong.

The Government reminded people who choose to undergo self-paid serology antibody testing at the airport they will still be required to present at boarding the confirmation of a room reservation of no less than 14 nights in a designated quarantine hotel in Hong Kong, or they will not be allowed to board flights for Hong Kong.

The Government announced earlier it will re-categorise overseas places into high-risk, medium-risk and low-risk groups, and implement boarding, quarantine and testing requirements based on the risk levels under the vaccine bubble concept and risk-based principle from August 9.
