Here's the lowdown on COVID-19 tests right now

COVID-19 is back and so is testing. (Double ugh.)

The COVID surge has us scrambling plans for holiday parties, travel to grandma’s house and return to office. It’s also creating a mad rush for COVID tests.

Welcome (back) to our onerous new reality, with vaccine mandates, masks requirements and testing protocols. And with testing comes the oh-so familiar questions: When were you tested? Where? Which kind of test?

I was thinking about the sheer volume of human, never mind economic activity associated with COVID testing and decided to delve into this for my column, focusing mostly on rapid tests, because that’s where much of the action is right now.

Testing has certainly become part of my life. Not quite like brushing my teeth, but like grocery shopping, which is to say once a week or so. Since Nov. 1 for instance I’ve been tested nine times, (most recently yesterday) and I anticipate a similar cadence going forward. I’m seeing family members and co-workers getting tested in increasing numbers and frequency as well. (Your experience may vary of course.)

A few months ago it looked like the need to test was winding down, but the variants and especially Omicron reversed that trend. Not only did we the people think testing was going away, (remember the days of scheduling PCR tests at a doctor’s office?), but so did at least one test maker, more on that below.

Before we get into the current situation with tests, let’s do a quick 101. As you may know (and forgive me if this is elementary, Watson), generally speaking there are two types of COVID tests at this point; the first being molecular tests, the most common being PCR (reverse transcription polymerase chain reaction, if you will) tests that usually require a lab. (Yes, there are also some molecular tests using for instance CRISPR technology, as well as “isothermal nucleic acid amplification, digital polymerase chain reaction, microarray analysis, and next-generation sequencing.” Got that?)

The second type of tests are antigen or rapid tests, which can be done on site (school, office, party, etc.) or even at home, which as I said I will focus on.

PCR tests detect the presence of the virus itself and are more accurate, but more expensive and take more time to produce results. Antigen tests, according to the CDC "detect the presence of a specific viral antigen, which implies current viral infection" and as "rapid tests" suggest, take only 15 minutes of waiting time, with the whole process requiring less than a half hour. Rapid tests are also cheap but less accurate.
