Free nucleic acid countries use: first, the medical insurance fund. At present, about 8% of the cost of free nucleic acid testing in various places is the second in the medical insurance fund, which is the local finance, and the local government will take out part of the money, which is about 2% of the cost of nucleic acid. The third is the national anti-epidemic special fund, which is directly allocated by the state finance and directly allocated to the local finance for special purposes. Although it is said to be free nucleic acid, everyone should know that whether it is the central government or the local government, the "government commitment" is still the money in the pockets of the people. When the medical insurance money is spent, you will find that many medical services will be discounted, some good drugs will not be available, reimbursement will be postponed, expensive and good services will not be covered by medical insurance, and a series of negative effects will exist for a long time.
