One simple test for almost all virus

And is that, if it is already made the serum for the virus, that need be used still with the antibody alive, so with the serum made from the blood of the animal that is reacting to the exact virus, the doctor would mix the blood of the suspect person with the serum and see in the microscope if the virus that is in the blood of the person is break by the antibody, see the antibody is like a key if the virus isn’t the same of the serum the key would not fit together, the virus is the lock, another way is that find a colourant that react with antibodies if the colourant change the colour showing that the antibody react with the blood in test will be proved that was virus in the sample.
