What does a positive nucleic acid test mean? Many people don't know much about COVID-19 testing. If the nucleic acid test is positive, it means COVID-19 and needs to be isolated and treated. This site will provide you with answers to nucleic acid testing, hoping to help everyone.

What does a positive nucleic acid test mean?

A positive nucleic acid test result means that the patient is confirmed to be a COVID-19 patient and isolation measures are required.

In terms of clinical practice, in addition to the new coronavirus, there are also SARS, MERS and Ebola. In addition, there are many influenza viruses in this season every year. The early symptoms of these viruses are similar, and when they are added to the lung symptoms, there is actually no obvious difference in imaging. This is why nucleic acid tests are needed to confirm the diagnosis.

Does a positive nucleic acid test mean it is definitely coronavirus?

How to determine whether a person is infected with the new coronavirus? Our previous method has always been to conduct two nucleic acid tests on the patient. A positive result means infection, and a negative result means no infection. If both tests are negative, it means that the patient is not infected or has been cured!

However, the appearance of a patient in Hangzhou completely broke this conclusion! The patient was diagnosed after 7 nucleic acid tests! This makes people wonder if those who have been tested and confirmed to be free of the disease may still be potential carriers! After they become "slippery fish", they are likely to become new sources of infection!

Can patients with COVID-19 who test positive again infect others?

Through monitoring, it was found that these patients did not infect others, and some patients turned negative again when tested for the new coronavirus nucleic acid. The new coronavirus is a new virus, and the pathogenic mechanism, the full picture of the disease and the characteristics of the course of the disease need to be further understood. It is necessary to further strengthen the management of discharged patients, conduct 14-day medical observation, strengthen follow-up, health monitoring and health guidance, and organize experts to further study this situation and further deepen the understanding of the entire process of the occurrence, development and outcome of the disease.

Colds are also caused by viruses. We carry viruses and coexist with them. So, asymptomatic carriers of the new coronavirus have strong immunity, just like us before we caught a cold; cured people are positive and have restored immunity, just like us after we have recovered from a cold. But this virus is highly contagious and has bad consequences. Before effective anti-drugs appear, social contacts should become cautious; after they appear, they should be kept on hand like cold medicines, or vaccinated. They may coexist for a long time.
