I was surprised to hear Sanjay Gupta (CNN) say this morning (4/28/20) that there is significant disparity in the accuracy of the COVID-19 Diagnostic testing. He specifically mentioned that the inaccuracy is as high as 15% in reporting false-negatives.

Has the inaccuracy of the various tests for COVID-19 been publicly reported?

NPR and Others have reported, but what I am looking for is clinical peer-reviewed reports or papers that compare the various COVID-19 diagnostic tests for accuracy, particularly false-negatives.

    I think we need an exact quote of what he said. – Graham Chiu Apr 28 at 22:30

    And I think you're supposed to show some element of research in your question. – Graham Chiu Apr 28 at 23:52

    @Fizz, but I take your point and will edit the question to be specific to the diagnostic tests (do you currently have COVID19 versus did you develop antigens) – BobE Apr 29 at 14:38

    No paper neither, but some weeks ago, Kekule (a German virologist and epidemiologist who is very prominently in the media right now) mentioned around 20 - 30 % false negative PCR tests due to difficulties with sampling (i.e. the swab not picking up the proper material) and that preferrably two swabs should be taken. – cbeleites unhappy with SX Apr 30 at 15:21
