It’s likely a late false positive. Remember that this is a lower respiratory tract infection so it takes up to 90 days to turn over the lowest parts of this system. We are alternating positive and negative for up to three months. This means he had the disease and cleared it most likely as the test checks for any virus particle even if dead or inactivated
Thank you for the insight. Hope you’re doing well!
Of course that’s a reasonable assumption.
Other explanations- such as that it was an error are reasonable too.
Would love to see more application of antigen tests.
Despite their limits they would be a terrific public health tool.
Especially in schools.
