Researchers develop a fast, accurate, low-cost COVID-19 test:

A new low-cost diagnostic test for coronavirus disease 2019 (COVID-19) quickly delivers accurate results without the need for sophisticated equipment, according to a study published August 27 2020 in the open-access journal PLOS Pathogens by Teng Xu of the Vision Medicals Center for Infectious Diseases, Tieying Hou of the Guangdong Academy of Medical Sciences, Bing Gu of the Affiliated Hospital of Xuzhou Medical University, Jianwei Wang of the Chinese Academy of Medical Sciences and Peking Union Medical College, and colleagues.

[...] In the new study, the researchers developed an alternative COVID-19 test by leveraging CRISPR-based technology, which has been widely used in recent years for gene editing. The assay, named CRISPR-COVID, enables high-throughput detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) -- the virus that causes COVID-19. CRISPR-COVID delivers comparable sensitivity and specificity as mNGS within as short as 40 minutes. When produced at a large scale, the material cost of a CRISPR-COVID test could be less than 70 cents, suggesting that CRISPR-COVID is a competitive alternative not only technologically but also financially.

    What happened to 'pick 2 out of 3'?

    If you keep into account that the development of such tests (or vaccines) is anywhere but fast, I don't see a contradiction.
    Once the method is known, producing them is not necessary constrained by the "pick 2".

    Also note that they only mention the material cost, not the total manufacturing cost.

    In theory you could make anything starting from hydrogen and smashing it together sixteen ways till Sunday and you'd have a low material cost and a ginormous manufacturing cost...
