Yeah, IgG, IgM can wane.
What you’re saying indicates estimates of infected who were unaware are underestimates.

Yes, but my primary point is that we could find who already had it, with enough time, money, people, and equipment. But the cost would run in the billions, and take 9 months orlonger. And tie up equipment and personnel...just too expensive and take too long.
But precise antibody tests are there, though expensive. And the testing would need to go into super detail and precision, or they’ll just miss the memory cells etc.
