The nucleic acid test ct value is the NeoCrown test cycle count threshold that can be used to determine if a person is infected with NeoCrown virus. The higher the nucleic acid test ct value, the lower the level of Neo-Crown virus in the sample. Typically, the amount of virus within the test sample is low, and direct testing of the sample often fails to detect the virus. Therefore, the low concentration of virus contained in the sample can be amplified exponentially to achieve a higher concentration, thus facilitating virus detection. The ct value of the nucleic acid test refers to the number of exponential amplifications required to accurately detect the new coronavirus. the higher the ct value, the fewer the number of exponential amplifications required to detect the new coronavirus, which further indicates that the new coronavirus content in the sample is less. The current international standard for ct values for nucleic acid testing is greater than or equal to 35, and if the patient’s nucleic acid sample meets this standard, then the patient is not infected with Neocollins.
