   1.                                                   Your statements that:
(i) you have not independently verified the accuracy or
                                                        completeness of third
party data, (ii) your internal research has not been verified by any
                                                        third party and (iii)
investors are cautioned not to give undue weight to any such

                                                        responsibility with
respect to the third party information and internal research. Please
                                                        either delete these
statements or specifically state that you are liable for such information.

Prospectus Summary, page 1

2.       We note your disclosure that your product may provide a market
solution "if cleared,
         authorized, or approved by the U.S. Food and Drug Administration."
Please revise to
         clearly disclose, if true, that you intend to label and distribute
Symphony as an RUO
         product in the U.S. while you pursue 510(k) clearance from the FDA to
use Symphony
         for in vitro diagnostic use.
3.       Please revise your disclosure here and in the Business section to
provide appropriate
         context for various conclusions and predictions as to the performance
of your product
         candidates and revise and/or remove any statements that imply safety
or efficacy as safety
         and efficacy determinations are solely within the authority of the FDA
or similar foreign
         regulators. For example, we note statements that RUO use in Japan has
resulted in
         "validation of the symphony platform," that results from your device
"appear to be as
         accurate as those performed in a laboratory," that your diagnostic
product "provide[s]
         results within 20 minutes," "reduces test result time from days to
minutes" and your
         product candidate "will eliminate the number of operational
touch-points    from    sample-
         to-result    from six to two." Please revise this disclosure and
similar statements throughout
         your prospectus to remove any suggestion that there is an expectation
that your product
         candidate will be effective or will have improved performance. You may
provide a
         summary of the data that you used to draw these conclusions but not
the conclusions or
         predictions, and such discussion is more appropriate in the Business
section where full
         and proper context can be provided.
4.       We note your disclosure that you are "positioned now to complete the
last regulatory
         stages of development needed to move to commercialization in the
United States." Please
         revise to clarify where you currently are in the regulatory process
and the material steps
         that you need to complete, including, if applicable, any clinical
trials that must be
         conducted or regulatory applications that must be submitted.
5.       We note your disclosure that Toray Industries is your development
partner and investor.
         Please revise to explain the nature of Toray Industries' investment in
your company.
         Based on your disclosure, it appears that Toray serves as a licensor
and supplier
         only. Please also revise your summary to clearly state that you
license the core technology
         used in your Symphony platform and test cartridge product candidates
from Toray
         Industries.
6.       Please revise the Prospectus Summary and Risk Factors to highlight the
auditor's
         explanatory paragraph regarding your ability to continue as a going
concern. Your
         disclosures should describe the potential consequences to your
business if you are unable
         to raise additional financing.

7.       We note your disclosure that you intend to use approximately $5.0
million to obtain
         regulatory approvals. Please revise to disclose for which product
candidates you intend to
         seek regulatory approval, in which jurisdictions and through which
regulatory
         pathway using the proceeds from this offering.
Business
Our Symphony Platform, page 42

8.       We note your disclosure that the Symphony platform is an innovative
and proprietary
         technology platform that in clinical trials appears to provide rapid,
highly sensitive,
         accurate, and simple measurements of key diagnostic biomarkers found
in whole blood.
         Please revise to clarify if these clinical trials were conducted by
the Company or a third
         party. Please also expand your disclosure to include a description of
how the clinical trials
         were conducted and the results observed that would support the above
statement.
Manufacturing, page 44

9.       Please revise to highlight that pursuant to your agreement with Toray
Industries, you are
         required to use Toray to manufacture test cartridges for a period of
three years.
Regulatory Strategy, page 45

10.      Please provide the basis for your statement that your Symphony IL-6
product candidate
         could also be used with confirmed COVID-19 illness. Please revise to
disclose whether
         you have tested your product candidate for this indication and, if so,
disclose the results of
         such testing.
11.      We note your disclosure that your clinical studies are being conducted
at The University
         of Texas, Southwestern Medical Center, Dallas, Texas and Parkland
Clinic, Dallas, Texas.
         Please revise to disclose how many trials are being conducted and for
each trial being
         conducted when the trial began, the current status of the trial and
when you expect the trial
         to be completed.

12.      With respect to your table on page 46 showing your expected timeline
for your product
         candidates, it appears to be premature and speculative to provide the
estimated time to
         market for your product candidates given that it appears that you have
yet to complete
         material steps in order to commercialize your product candidates.
Please revise this table
         to provide the status of FDA approval of your various product
candidates, including
         clinical trials or studies you must complete, when you began clinical
trials or studies and
         when you expect to complete them and whether you have submitted or
when you intend to
         submit an application for approval to the FDA. Please also explain to
us why you have not
         included Toray Industries next to your Symphony    IL-6 product
candidates. In this
         regard, we note that you license technology related to Symphony and
the detection
         cartridges.
Intellectual Property, page 47

13.      We note that you do not currently hold any patents directly but that
you have an exclusive
         license with Toray to use their patents and know-how related to your
Symphony platform
         and test cartridges. Please revise your intellectual property
disclosure to clearly identify
         each material licensed patent or patent family, the type of patent
protection granted for
         each technology such as composition of matter, use or process, the
specific products or
         product candidates, product groups and technologies dependent on each
patent, and the
         patent expiration dates and applicable jurisdictions, including any
foreign jurisdictions.
License Agreement, page 47

14.      We note that you intend to file as an exhibit a Lease and Supply
Agreement with Toray
         Industries. If this is not the license agreement that you have with
Toray Industries, please
         file the license agreement as an exhibit to your registration
statement pursuant to Item
         601(b)(10) of Regulation S-K.
15.      We note your disclosure that you are required to pay a 15% royalty fee
based on a
         percentage of    Net Sales    of products. Please revise to disclose
the royalty term.
Description of Our Securities, page 72

16.      We note that you refer shareholders to, in part, the applicable
provisions of the Delaware
         General Corporation Law. It is not appropriate to qualify your
disclosure by reference to
         information that is not included in the filing or filed as an exhibit.
Please revise
         accordingly.
