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. Apr 28, 2020 at 22:30

    And I think you're supposed to show some element of research in your question. Apr 28, 2020 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)

    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.
