RT-PCR testing gives you a positive/negative result for presence of SARS-CoV-2, but does NOT identify the specific variant. For that, CDC takes a random sampling of positive test specimens and does whole genome sequencing. It’s through this process that the actual variant is identified.
This is done on a subset of positive specimens because it costs about $130 to sequence the genome of a single sample. This is how the statistics are compiled on which variants are active.
Thanks! This is the conclusion I came to in the comment above.
ROTF!!
We're supposed to believe that the people responsible for the so-called infrastructure bill give a rat's hairy hind end about cost?!
🤣🤣🤣🤣
