In general, a ct value of less than 37 for the new coronavirus can be initially diagnosed as positive, rather than greater than a certain value being positive, and further refinement of the new coronavirus nucleic acid test is required for an initial positive diagnosis. The new coronavirus ct value generally refers to the circulating threshold of the new coronavirus, which can be used to determine the concentration of nucleic acid content in the test sample. Typically, the lower the ct value, the higher the amount of Neocollins in a person’s body. A ct value of 37 or less is initially considered positive, 37 to 40 requires repeat testing for accurate results, and a value greater than 40 generally means the patient is negative. A ct value of less than 37 does not necessarily mean that the patient has been diagnosed with the new coronavirus, but is only a preliminary diagnosis that needs to be followed up with clinical observation and nucleic acid testing to confirm the diagnosis. After the detection of ct value, should be timely to the hospital consultation, the results of the positive with the follow-up examination, to avoid delays in the diagnosis of infected people and isolation, resulting in the spread of the virus, infected people aggravate the condition.
