1068 is it true that you sent a text message at the beginning saying that the nucleic acid mixed tube was positive?

Yes, it is true that the nucleic acid mixing tube is positive. The following is a detailed explanation:

1. Positive mixed-tube nucleic acid means that the negative and positive results of nucleic acid detection are inconsistent, that is, sometimes false negative or false positive results appear.

2. False negative means that the infected person does carry the virus, but the test results are negative. This may be caused by improper sample collection, low viral load or laboratory operation errors.

3. False positive means that people who are not infected with the virus are wrongly diagnosed as positive. This may be caused by cross contamination, sensitivity problems of the kit or laboratory operation errors.

4. Nucleic acid detection is one of the most commonly used COVID-19 detection methods, but it is not absolutely accurate. Therefore, when interpreting the nucleic acid test results, it is necessary to combine the clinical symptoms, epidemiological history and other detection methods to ensure the accuracy.

Summary:

When the nucleic acid mixing tube is positive, false negative or false positive results may appear. Accurate interpretation of nucleic acid test results requires comprehensive consideration of many factors to ensure the accuracy of diagnosis.

Extended data:

Nucleic acid detection plays an important role in the diagnosis, prevention and control of COVID-19, but its result may be influenced by many factors. In addition to the positive nucleic acid mixing tube, there are other factors that may lead to the deviation of nucleic acid detection results. Therefore, in the prevention and control of epidemic situation, it is necessary to combine other clinical information and detection means to make an accurate judgment.
