CDC COVID-19 Test Kit is Error-Prone Says Director of US Pub
A recently published peer-reviewed article reported significant errors with CDC’s COVID-19 RT-PCR test. Author Sin Hang Lee, director at Connecticut’s M

The CDC itself recently stated in the following document Page 42.

The analytical sensitivity of the rRT-PCR assays contained in the CDC 2019 Novel Coronavirus (2019- nCoV) Real-Time RT-PCR Diagnostic Panel were determined in Limit of Detection studies. Since no quantified virus isolates of the 2019-nCoV were available for CDC use at the time the test was developed and this study conducted, assays designed for detection of the 2019-nCoV RNA were tested with characterized stocks of in vitro transcribed full length RNA (N gene; GenBank accession: MN908947.2) of known titer (RNA copies/µL) spiked into a diluent consisting of a suspension of human A549 cells and viral transport medium (VTM) to mimic clinical specimen

Ie. we don't have a copy of the virus, so we used one from the warehouse that we think is similar as they are "also coronaviruses".

Questions are being asked, by the right people

What Is a Cq (Ct) Value?
Don’t stay confused by Ct values! We’ll guide you through what they are, how to calculate them, and troubleshooting issues.
Higher C q values (above 38 cycles) mean lower amounts of your target nucleic acid. High C q values can also indicate problems with the target or the PCR set-up, as outlined later in the pitfalls section of this article. Your PCR instrument will collect fluorescence data during each cycle.
