Information on Faulty Testing


TESTING-ANTIGEN, PCR, ANTIBODY

  • Antigen tests are designed to detect specific proteins unique to Sars-Cov-2 (The virus that causes Covid-19)

  • A positive Antigen test “implies a current viral infection.”

  • Antigen tests are designed to detect direct evidence of the presence of the virus.

  • Due to the fact that Antigen tests are LESS SENSITIVE, they are more likely to give false negatives (meaning a positive case, but you test negative when you are really positive). For this reason, Antigen tests are usually followed up by a PCR test (Molecular test RT-PCR) to confirm.

  • Antigen testing are intended for symptomatic* individuals within the first few days of onset.

  • PCR Tests (Polymerase Chain Reaction)-are designed to detect specific genetic material from the virus

  • “Complete live viruses are necessary for transmission, not the fragments identified by PCR.”5

  • PCR tests are more likely to have FALSE POSITIVES (testing positive, but really being negative), due to variations in how the tests are evaluated by each lab.

  • PCR Testing is the PRIMARY SOURCE of testing in the USA.

  • Therefore total positive PCR test results (which are 478,715 on December 28, 2020 in NC) are LIKELY higher than the actual number of true cases….

  • Further complicating the reliability of PCR tests-one study suggests that in some instances the SARS-COV-2 genetic material may INTEGRATE with and become a permanent part of the infected persons DNA. This would cause them to test (+) in a PCR test indefinitely.

  • Antibody tests detect the immune systems response to infection whether PAST or PRESENT. Therefore, it should not be used to diagnose current infections

  • Antibody tests may also indicate past or present infections from OTHER VIRUSES IN THE CORONAVIRUS FAMILY other than Sars-Cov-2/Covid-19. Making them even less reliable.

All testing is LESS ACCURATE when NOT accompanied by CLINICAL SYMPTOMS***

“Another limitation to capturing accurate data is method of testing. Real-time reverse transcriptase polymerase chain reaction using nasopharyngeal swabs can detect RNA fragments from SARS-CoV-2, which could potentially affect the results. "It's really hard to know what is actually infected virus versus just fragments of RNA that make the test positive," Dr. Trueger said.”
