Judgment of the Court of Appeal of Lisbon states that “In view of the current scientific evidence, this test is, by itself, incapable of determining, without a reasonable margin of doubt, that such positivity corresponds, in fact, to the infection of a person by the SARS-CoV-2 virus, for several reasons, of which we highlight two:

Because this reliability depends on the number of cycles that make up the test;

Because this reliability depends on the amount of viral load present.”
