Abstract: Disclosed is a nucleic acid test kit, comprising a Cpf1 test system, said Cpf1 test system comprising: a guide RNA, a Cpf1 protein, a nucleic acid probe, and a manganese ion-containing solution. Also provided is a mutated Cpf1 protein and a nucleic acid test kit containing the mutated Cpf1 protein. Also provided is a crRNA for testing coronavirus nucleic acid, and a nucleic acid test kit containing said crRNA. Further provided is a use of the nucleic acid test kit, and a test method for the nucleic acid. When the nucleic acid test kit, mutated Cpf1 protein, or crRNA of the present invention are used for nucleic acid testing (for example, testing the nucleic acid of a SARS-related coronavirus or MERS coronavirus), the signal strength during the test is substantially enhanced, and the test time is thus reduced and the test efficiency improved. In addition, the sensitivity, specificity, and accuracy are high, the test is visual, the cost is low, the operation is simple and convenient, and no large-scale complex t equipment is required.
