disclosures on pages 83-85, revise to highlight the impact of the
                                                        COVID-19 pandemic on
your business, including with respect to product mix, costs and

                                                        briefly what the

3.       With regard to the July 23 announcement, please revise to clarify the
importance of this
         arrangement so that it is clear why you are highlighting this
announcement in your
         Summary. For instance, indicate whether you have derived material
revenues to date from
         the arrangement and whether it is exclusive in nature. Also file the
agreement as a
         material contract or advise. As applicable, refer to Compliance
Disclosure Interpretations,
         Regulation S-K, Question 146.04 for additional guidance.
4.       Your Summary disclosure suggests that you developed the two COVID-19
tests, that you
         own the technology, and that you hold the relevant EUAs; however, your
disclosures on
         pages 34-35, 37 indicate that Bio-Rad developed the tests and that
they own the
         technology and hold the relevant EUAs. We further note that your March
20, 2020
         and May 19, 2020 press releases indicate that you and Bio-Rad are
partners and
         collaborators with respect to these tests and that your disclosure on
page 129 indicates that
         Bio-Rad is your supplier. Please revise to clarify or advise.

5.       With reference to your disclosure on page 86, please revise the
Summary to explain that

8.       We note that your amended and restated certificate of incorporation
will provide that the
         Court of Chancery of the State of Delaware will be the exclusive forum
for "substantially
         all" shareholder claims, including "any derivative action." Please
disclose whether this
         provision applies to actions arising under the Securities Act or
Exchange Act. In that
         regard, we note that Section 27 of the Exchange Act creates exclusive
federal jurisdiction
         over all suits brought to enforce any duty or liability created by the
Exchange Act or the
         rules and regulations thereunder, and Section 22 of the Securities Act
creates concurrent
         jurisdiction for federal and state courts over all suits brought to
enforce any duty or
         liability created by the Securities Act or the rules and regulations
thereunder. If the
         provision applies to Securities Act claims, please also revise your
prospectus to state that

and regulations
         thereunder.
