I've been super tired the last few days. Probably related to the COVID going through the house that I never tested positive for (even after trying a throat swab). The kids are full of energy but also very fragile so it's a bad combination.

I'd love to know the cause behind the false negatives RATs - is it the strain of the virus, the methodology of the sampling, or something about the individual themselves? It's seems to be quite a high rate for a false negative...

I tested negative with one brand and positive with another brand ten minutes later. RATs are definitely not created equal. I've got both brands still in the cupboard (just in case) but can't remember which is which.

But that was last year and I wouldn't be surprised if mutations have pushed the virus past what the tests can detect.

Other than being super tired I haven't really had other symptoms. It's possible the infection is being fought off enough to keep the viral shedding below detectable levels. It's also possible I have a different virus that isn't COVID.

I'm in a flu study that gives us PCR tests when we get anything, but they only last week finished for the season so I didn't get to do a PCR to find out. They test for about 10 or 15 different viruses, so even if it's just a cold you often still get to find out exactly what virus. They still only get an answer about 50% of the time.
