my doubt - 3 negative tests
my doubt is due to the fact I had 3 negative tests (only control lin appeared) but I cannot rember if I pushed 3 times the device as per your procedure.
I am sure I have seen both pink spot after one minute and then a clear control line.
Is this enough to be 100% sure my tests are really negative?
Am I 100000% negative?
I did the tests after more than one year from exposure.
