I did a few of those stupid tests, probably 8/9 in total. After checking on the symptoms my early tests were positive, and the next 5/6 negative the following week.
I agree they aren't perfect, but seemed to tie in with how I felt.
Some sort of virus (to force injection of other chemicals or not) seems hard to ignore - manmade/5g related, only a few know for sure.
