In other words, there is no way to know that you have it, unless you became ill from it.
My understand is that:
The virus is chopped up by at least two different enzymes.
The little pieces are reproduced many times over.
The little pieces are separated by type.
The little pieces are then sequenced individually.
The sequences are then fitted together logically.
People go to universities and learn how to do this.
“Researchers sequenced coronavirus samples at the microbiology laboratory of the University Hospital of Badajoz in Spain on April 15.”

“Ortho’s new qualitative VITROS® Anti-SARS-CoV-2 Total N antibody test is designed to capture the nucleocapsid protein, detect total antibodies to the COVID-19 virus, and is intended for use as an aid in identifying individuals with an adaptive immune response to SARS-CoV-2. The test offers 99.2% specificity and excellent sensitivity. Ortho is the first company to have an EUA for both a quantitative IgG antibody assay targeting the spike protein and a total assay targeting the nucleocapsid protein.”
Every once in a while the truth slips out of some random source.
Thank God.
