You point out a news article in which one particular company reportedly had some false positives, which is surprising because in lab tests their test didn't have false positives.
According to a Harvard study and the CDC, the most common type of tests has a false negative rate up around 20% and a false positive rate of about 3% which the false negatives increasing if the test isn't taken within the first few days of symptoms.
If the antibody level is low, that'll give a negative - there just isn't enough antib
You got most of that right. Sequencing for Covid (or any coronavirus) has some important caveats though.
First, they're RNA viruses, so you need to do reverse transcription PCR. You could say "reverse transcription PCR is just one enzyme different from regular ol' PCR", and you'd be mostly right. Hence all the other requirements, including good primers and tuning of annealing temps, etc apply as well.
Second, RNA - even viral genome RNA - is inherently less stable than DNA. This is largely because RNA
I am unaware of any manufacturing requirements in the service of national security that would necessitate the commandeering of a Tesla factory at this time.
Maybe not having hundreds of thousands die of an avoidable illness?
We're on track for achieving half of the deaths we suffered during all of WWII in less than one year. Back then, all those people sacrificed their lives in an effort to fight off conquest by totalitarian enemies. Now, people are apparently sacrificing themselves at an even faster rate for the freedom not to wear a mask and to act like things are business as usual.
Right now, this must truly be the greatest generation, sacrificing so much for
Was tested for covid four times today. Two tests came back negative, two came back positive. Same machine, same test, same nurse..."
The false positive rate on those tests is pretty low, but the false negative is pretty high. Chances are he's positive

Manufacturing cars is not essential in the short term.
During WWII, we went four years without any new cars at all, and we managed just fine.
