Its necessary to note that evidence has not demonstrated any instance of saline nasal irrigation and/or gargling at preventing COVID-19, and that gargling is not by any means a recommended standalone cure or treatment. These tests are highly specific because they are based on the unique genetic sequence of SARS-CoV-2. For a better experience, please enable JavaScript in your browser before proceeding. Analysis of Factors Causing False-Negative Real-Time Polymerase Chain One team of researchers recently studied the effects of nasal irrigation on COVID-19 and determined that this simple, at-home practice could very well help lessen a person's viral load .

The main reasons for false positive results are laboratory error and off-target reaction (that is, the test cross-reacting with something thats not SARS-CoV-2). that is an equivalent alternative amplification method to polymerase chain reaction (PCR) . Moreover, I would also recommend at least doing a rapid home test if you are planning to see someone who is immunosuppressed or elderly, so you dont inadvertently infect them, saysThersa Sweet, PhD, MPH, associate teaching professor of epidemiology and biostatistics at Drexel University in Philadelphia.
