The CDC kit produces results within four hours.
Stanford: "The Stanford test uses a technique called reverse-transcriptase polymerase chain reaction, or RT-PCR, to rapidly identify the presence of viral RNA in swabs from the noses of potentially infected people."
CDC: "The test kit, called the Centers for Disease Control and Prevention (CDC) 2019-Novel Coronavirus (2019-nCov) Real-Time Reverse Transcriptase (RT)-PCR Diagnostic Panel (CDC 2019-nCoV Real Time RT-PCR), is designed for use with an existing RT-PCR testing instrument that is commonly used to test for seasonal influenza."
So 4 hrs vs 12-24 hrs for test results.
But are both accurate to the same degree?
