To conduct an infection detection test, matrix of tests based on salivation*, and these tests are less penetrated, and in some cases they are more sensitive than tests that depend on taking a nasal tin. It is the Brennan saliva test: "It is somewhat available to provide a sample of saliva again." To reach a monitoring level, and as soon as the saliva sample taken to take the "Kofidschild" test to the laboratory, it is added to the sample "Beginnings", so that it can be easily determined and considered a positive sample. The interval between the Cofide disease detection testing and obtaining results is a decisive factor in assessing any diagnosis; In addition to the sensitivity of the tests in general, the antigenic detection tests depend mainly on nasal swabs, although the researchers are working to reach a precise copy based on examining saliva, and supporters of the antigenic detection tests believe that the speed of these tests and their low cost make them more appropriate as a tool of tools Public health, especially that which must be sent to the laboratory, and the excessive sensitivity of the serial polymerase reaction tests is one of the main problems in the context of public health, it says that cases of using the serial polymerase reaction tests based on examining saliva are very different from cases of use of antigenic detection tests, and sensitivity Serial polymerase reaction tests based on saliva examination equivalent to the sensitivity of the serial polymerase reaction tests based on nose swarms, so what is the test that you will do? The answer will depend on the degree of allergies required to detect infection, because the presence of a more sensitive test, such as a serial polymerase reaction test based on saliva examination, is I injured? Will I be a carrier of infection tomorrow? ”The test detection tests are useful in determining whether the person is a transmission of infection or not, are I a transmission now?” Although one of them is no longer a transmission of infection, the tests of the serial polymerase reaction to the saliva examination may continue to show a positive result due to its extreme sensitivity. Games, and this would exclude the necessity of moving to the testing facility, although it must be sent to the laboratory for analysis, which includes all directions and materials necessary to provide the sample and hand it over to the sampling point for testing a laboratory.
