I am assuming they are the lateral flow tests which tend to miss quite a big amount of positive cases?
Lateral Flow Tests missing a large number of positive cases is not necessarily negative.
Lateral flow tests and PCR tests are very different tools for very different scenarios. PCR are good to spot that you have had the virus, but will still return positive long after you are no longer infectious. Lateral Flow Tests are a better indicator of infectiousness.
I've found some of the stuff Tom Chivers, and Tim Harford have written on this subject very informative

can someone ELI5 to me why what england are doing is wrong and bad
Its a trade off, we have to take 10 Indian wickets to win the game.
On the other hand India have to score more than (currently) 387. There are 3.x sessions left (x is around 8).
4 sessions is more often than not sufficient to bowl a team out in their last innings, 100 runs per session is not an unobtainable amount of runs
Its a balancing act. But also the longer a test match goes, in general the harder it is to score, given the deterioration of the pitch. If we declare now we should win, but Bangladesh thought exactly the same 2 days ago and came unstuck!
Btw I have Scottish ancestors,and after time even I managed to understand cricket to some extent.
Ffs, just get a jab when you are called. Compared with the massive benefits between having a jab, and not having a jab, the differences between vaccines are both marginal, and also no where near as clear cut as seems to be portrayed.
Both my parents have been inoculated, and tbh, I haven't even bothered to check which one they are having. We are lucky, my wife's parents have no chance of getting a vaccine this year, they need to wait until the rich countries have fed from the trough!
