Corona's report should be negative, it does not mean that you are not infected. This is because there have been many cases in which the patient was infected but it could not be confirmed in the initial investigation. There have been many such patients around the world who were suffering from symptoms of COVID-19 like cough, shortness of breath and high fever, and the reports were found to be negative when they were tested.
The doctors advised him to stay at home and to come back once the symptoms progress. After a few days, when the condition started getting worse, then went to the doctors. The doctors took samples for their re-examination and when the report came a short time later, it also turned negative.
One reason for this is to take nasal discharge from within the nose while taking a sample. For this, the swab also has to rotate in the nose for a long time. The weak technique can also be the cause of false negatives. Indeed, cases that were negative at first then found positive or infected, but their investigative report is negative, they are called a false negative.
The infection has not begun
At present, the prevalent corona screening method makes it possible that the infection may not be caught. Currently, RT-PCR is being investigated by the polymerase chain reaction. Through this, the virus particles present in the breath are captured at the beginning of the infection. The American Center for Disease Control and Prevention (CDC) says that at times when something is found to be negative, it may mean that the infection has not started while taking the sample.
