Viral testing is one of the most important tools available in the fight against the new coronavirus, through which we can find out if we are infected with the virus so that we can take appropriate measures to protect ourselves and others. Negative and positive are very important concepts in virus testing, and here's what they mean.
I. What is a virus test?
Virus testing is used to determine whether a person is infected with the new coronavirus by detecting the nucleic acid of the new coronavirus in human samples (e.g., nasopharyngeal swabs, cough sputum, blood, etc.). Virus testing can be categorized into two types: one is PCR testing and the other is antibody testing.
II. What does negative mean?
Negative means that the test result is that the nucleic acid of the new coronavirus is not detected. This means that you are not currently infected with the new coronavirus, but it does not rule out that you have been infected or are in the incubation period. If you have symptoms or have been in contact with someone who is positive for the new coronavirus, it is recommended that you continue to monitor your health and get tested again at intervals.
Three: What does positive mean?
Positive means that the test result is a detection of the nucleic acid of the new coronavirus. This means that you are currently infected with the New Crown Virus and need to be isolated and treated immediately, as well as informing the relevant authorities and people who have come into contact with you to avoid the spread of the virus.
4. How do I get tested for the virus?
1. Choose regular testing institutions, such as hospitals and testing centers.
2. Sampling according to the requirements of the testing organization, such as nasopharyngeal swabs, sputum, blood and so on.
3. Send the sample to the testing organization for testing.
4. Wait for the test result, which usually takes 1-2 days.
5. Precautions for virus testing
1. Activities such as eating, drinking and smoking should be avoided before the test to avoid affecting the results.
2. Before the test, you should inform the doctor about your medical history and exposure history so that the doctor can make a comprehensive judgment.
3. After the test, regardless of whether the result is negative or positive, you should follow the relevant precautions to protect yourself and others.
