The reporter, Apoorva Mandavilli, tweets, “It turns out that the PCR, that old reliable workhorse, is both too slow and too sensitive for what we need”:

In a nutshell, the PCR test is run in cycles and the more cycles it takes to get a positive result, the less virus you have in your system:

In the U.S., the machines are calibrated at between 37 to 40 cycles, which, according to this report, is way too sensitive:

Note: We don’t have the numbers for every country, but India’s threshold is only 35:

A reasonable cycle threshold should be around 30:

The implications of this are massive:

We’re figuratively (and quite possibly literally) letting our neighborhoods burn down:

The argument here is we need the FDA to approve “rapid, less sensitive tests”:

What’s worse is that these labs aren’t even reporting back the number of cycles it takes to get a positive test, only yes or no:
