Reply to comment by celebratedrecluse in UK scientists create Covid-19 antibody test 'with 99.8% accuracy' by ziq
Possibly a silly question: in order to measure the specificity & sensitivity of the test, how do they find the ground truth about which patients do or don't have the antibodies prior to the development of the test for antibodies? I guess you could use a slower but more reliable test, but is there then some sort of chicken & egg problem?

an interesting epistemology question, which I am not qualified to answer. Perhaps someone else can chime in with more information and knowledge of this field, I would be very interested to learn about it
