SpletThe SARS-CoV-2 RT-PCR tests used in Australia have very high specificities and the strategy of using a second and/or third SARS-CoV-2 PCR assay with different gene targets increases the specificity of the PCR even further. The combined SARS-CoV-2 PCR testing experience of the PHLN laboratories is that the false positive rate is extremely low.
