Is it possible to test negative at the 12 week mark but positive later?

[Teak]

Yes, if you have put your self at risk again during the window period

[RainLover71]

well if you aren't a chemo patient or chronic IV drug user then how can you be.12 weeks is conclusive for you & the majority of the population.

[worrisome67]

I hope I'm not in that percentage

[RainLover71]

percentage of rarity for those group of people I mentioned is 3%

[RainLover71]

if you are healthy and not a chemo patient or chronic IV drug user then the percentage is zero.Infact 99% of people who are infected will test positive by 6 weeks

Percentage of rarity

[RainLover71]

No,unless you are a chemo patient maybe but it's extremely rare
