Strength of line on LFT - is it an indicator of viral load?

[2389Champ]

Hope this isn’t too random but just after info out of interest.

I felt a bit meh on the evening of 22/11. Assumed I was starting a light head cold, felt 100% next morning but did an LFT = negative.
Woke up on 24/11 with no taste/smell, did another LFT = line appeared immediately and very strongly. PCR confirmed result and now self isolating until 5/12

I’ve felt completely well all the time and a couple more LFTs were still very positive. My taste and smell suddenly returned after 5 days so out of interest, I did one more LFT. Line this time was very, very faint. Does this indicate that the covid is actually on its way out or maybe just a duff test?

Don’t worry, I’m still ‘doing my time’ Just curious, that’s all.

The definitely got stronger with dd over a few days when she had it.

I think you may be into to something there as I thought it seemed a bit like hcg in a pregnancy test - early pregnancy, faint line. Early covid or getting over it, faint line.

I had covid six weeks ago and had a very faint lft when my sons was Bright red, two days as I got poorlier mine got much stronger and brighter.

As I got better I took another lft and it was much fainter again and finally after 3 weeks was white with just the test line.

Yes I think so. A study was published recently where it was saying that LFT were pretty reliable as they were positive when viral load was high so therefore positive when at your most contagious. When the LFT is negative but pcr positive you may be less infectious. I’m not sure where the study was published but it was reported in the papers.
