Nope. The test that is available and used today indicates if virus RNA is present in the sample. The sample is taken from the pharynx mucosa, that's where the virus predominantly settles. Nucleic acids from the sample are isolated and then transferred to a PCR-machine in order to increase the chemical signal to facilitate detection. So:
- If there is no genetic material from the virus in the pharynx, you won't find it anywhere else in the person tested
- If virus RNA is in the sample, it will be detected 100%, because replication time of nCOV-2019 is extremely short and the virus is the most aggressive corona virus we have seen so far.
A negative test means the person does not accommodate any nCOV-2019 virus. Period.
Let's stick to the truth here. Stop spreading nonsense. We have too much of that in the thread already.
