My wife is required to submit to weekly testing for the coof. I asked the testing facility what Cycle Threshold they use for their tests. Here is the response:
**Our test does not use cycle thresholds (Ct). Ct is used for a qPCR test method, whereas we perform rRT-PCR. Our detection is given by flourescently tagged molecules that generate Median Fluorescent Intensity (MFI) based on the viral load of the collected sample. We test for multiple genes within the SARS-CoV-2 genome and have a different threshold for each. I hope that answers your question. **
I 'think' I understand but perhaps there is an anon in here that can give a brief explanation regarding accuracy etc.
The RT PCR test was revoked by the FDA - Why? It cannot tell the difference between influenza/ covid and the common cold. Although they revoked its use, they are allowing it to be used until Dec 31,2021. The real question is what is on the end of the swab they are collecting your sample with? If it is EO or Ethylene oxide - that is certainly not something you want to keep repeating.
