Confusing test results

[Laurel1]

On Monday I had a positive lft. I retested twice and both clear positives.
Went straight for a pcr which came back saying it could not be read. Did a lateral flow, faint positive. Did another, negative.
So I went for another pcr which came back again saying it could not be read. Lateral flow negative.
Yesterday Went for a pcr and result through this morning negative. Lateral flow negative!

I've booked a further pcr today. But I don't know what to think. Has it happened to anyone else like this? Works official line is I should go back. My colleagues view is they don't want me back in and give it to them for Christmas.

I've had a cough, fatigue, breathless and headache. But none of the 3 big ones.

Here's a pic of lft from Monday!

The three big ones aren’t the three “top” symptoms. The government is choosing, for whatever reason, to ignore this fact.

It may have been that the PCRs weren’t done properly? So make sure you don’t eat within an hour of testing and blow your nose well. Also try a postal one (if you did a drive through) or vice versa.

I've done drive throughs and walk throughs at different site and all done before I've had anything to eat in the morning.....
