Which test did she get? The PCR test is almost meaningless because it finds so many false positive results. For one thing the lab techs are magnifying the test samples 45 times and Fauci said that if you cycle (magnify) them more than 35 times you will get almost all false positive results.

• The performance of this test has not been established for monitoring treatment of 2019-nCoV
infection.

• This test cannot rule out diseases caused by other bacterial or viral pathogens.

"Positive and negative predictive values are highly dependent on prevalence. False-negative test
results are more likely when prevalence of disease is high. False-positive test results are more
likely when prevalence is moderate to low."

Negative results do not preclude 2019-nCoV infection and should not be used as the sole basis
for treatment or other patient management decisions.

Test performance can be affected because the epidemiology and clinical spectrum of infection
caused by 2019-nCoV is not fully known.
