Yu Changhai, chairman of the Hong Kong Testing and Certification Bureau and chairman of the Hong Kong Biotechnology Association, stated in the "Hong Kong Family Letter" that national testing can find invisible patients and interrupt the chain of virus transmission. He pointed out that as early as this year, a "mixed sample" method was proposed for testing to save the cost and time required for testing. The tester’s sample is divided into multiple groups, and the samples of each group will be mixed and tested at once. If a positive case is found, samples from the group can be taken out for review one by one.
If a group of ten people, the number of tests in Hong Kong can be reduced to 800,000 times
He gave an example. If ten people were formed into a team for testing, the number of tests for 8 million people in Hong Kong could be reduced to about 800,000 tests. He pointed out that the United States, Germany, and Mainland China have all adopted mixed sample testing, which is considered to be a feasible and effective method. If local public and private organizations can adopt the "mixed sample" method on a large scale, the "national testing" can be successful. .

He pointed out that the government has strictly regulated the procedures for laboratory operations, and the virus has been alive during testing.
He pointed out that earlier industry conferences were organized to discuss national testing, involving biotechnology, testing, academia and other sectors. They believed that "national testing" was more difficult to implement, including quality control, logistics distribution, and assurance. Information confidentiality, etc. But he pointed out that there is now a set of solutions to the problem, and the scientific and technical problems have also been solved. He hopes to identify most of the invisible patients, isolate them and treat them as soon as possible, so that the government can concentrate on protecting the people's livelihood in the future.
