Thank goodness. Then it's okay. No further spread
According to this article PCR is not an easy to perform
How false negatives are complicating COVID-19 testing
Part of the problem lies in locating the virus as its area of highest concentration shifts within the body.
The main nasal swab tests examine the nasopharynx, where the back of the nose meets the top of the throat. This requires a trained hand to perform and some portion of the false negatives arises from improper procedure.
But even if done correctly, the swab may produce a false negative. That’s because as the disease progresses, the virus passes from the upper to the lower respiratory system.
In these cases, the patient may be asked to try to cough up sputum — mucus from the lower lungs — or doctors may need to take a sample more invasively, when a patient is under sedation.
Daniel Brenner, an emergency physician at Johns Hopkins Hospital in Baltimore, Maryland, described taking a test after performing a procedure called a bronchoalveolar lavage.
This was done on a patient whose nasal swab returned negative three times, but who showed all the signs of COVID-19.
Eventually, the patient’s medical team placed a camera down his windpipe to examine the lungs, then sprayed fluid in and sucked out the secretions, which were then tested, resulting in a positive.
Uncertainty in clinical diagnoses is not new, and clinicians are well aware that no type of test for any condition can be considered perfect.
What makes COVID-19 different is its newness, said Sampathkumar.

This is exactly what I wrote many times. The PCR accuracy depends on the sampling site. Alveolar lavage has the highest reliabilty. These facts were well known for several months. It's not the fault of the PCR technique. It's the swab and that's why swabs from multiple sites are required.![]()
