And, there is conflicting evidence as to whether or not steroids taken this way will actually cause any decreased defense against the virus. These tests are highly specific because they are based on the unique genetic sequence of SARS-CoV-2. On the other hand, if you got a test for no particular reason and its negative, then its probably safe to go on about your business while taking the usual precautions: wear a mask, social distance, and wash your hands frequently. Where do things stand? If you think you may have a medical emergency, call your doctor or dial 911 immediately.

The authors of a recent preprint (a paper which hasnt yet been peer-reviewed, or independently verified by other researchers) undertook a review of the evidence on false positive rates for the RT-PCR test used to detect SARS-CoV-2.

A person gets tested before enough viral particles have accumulated in the nasal passages for the test to detect them. The rate decreases further, to about 20 percent, after three more days. One is the polymerase chain reaction (PCR) tests, which looks for traces of the viruss genetic material and is sensitive enough to detect infection in its earliest stage. The researchers noted that the general "benefit of topical nasal saline has been well established," explaining that the nasal lining serves an important role in the immune system, acting as the primary defense against inhaled viruses and bacteria. First, if you got a negative result from a rapid antigen test, consider getting a PCR test because its more accurate at detecting the virus.
