We rely on a limited number of suppliers, or in some cases, sole suppliers, for
some of our
laboratory equipment and supplies, page 19
9.   We note your disclosure that you source sequencers, reagents and certain
other laboratory supplies used
     in your laboratory operations from several sole suppliers. Your supply
agreements appear to be material
     contracts. Please expand your disclosure in the Business section to
provide the material terms of your
     material supply agreements, including each parties' rights and
obligations, financial terms, term and
     termination provisions.
      Please also file your supply agreements as exhibits to your registration
statement or tell us why you
      believe such filing is not required. Refer to Item 601(b)(10) of
Regulation S-K.
      In response to the Staff's comment, the Company has revised the
disclosure on pages 19 and 129 to provide
      additional clarification. The Company further advises the Staff that:
           (i) The Company generally sources laboratory equipment and supplies
from more than one supplier.
              These suppliers are typically trading companies which procure
such equipment and supplies from a
              variety of manufacturers. There are a large number of
manufacturers that are capable of supplying
              such equipment and supplies at similar qualities and prices. As
such, the Company does not believe
              that its business is substantially dependent on any particular
supplier.
          (ii) The company currently sources certain probes and reagents from a
sole supplier. Purchases from this
               supplier accounted for 11.3%, 14.9% and 7.3% of the Company's
total equipment and raw materials
               purchases in 2017, 2018 and the nine months ended September 30,
2019, respectively. There are
               multiple replacement suppliers that are capable of supplying the
same supplies at similar qualities
               and prices. As such, the Company does not believe that this
supplier is material to its business.
          (iii) As replacement suppliers are readily available, the Company
does not enter into framework
                agreements with its suppliers; instead, it enters into
short-term supply agreements with its suppliers
                on an as-needed basis, each specifying the quantity, quality,
delivery and payment terms for the
                respective batch of laboratory equipment and supply the Company
purchases. These agreements are
                entered into in the ordinary course of the Company's business
and the Company's business is not
                substantially dependent on any of these supply agreements.
             Based on the foregoing, the Company does not believe that any of
its supply agreements qualifies as a
             "material contract" as defined under Item 601(b)(10) of Regulation
S-K which needs to be filed as an
             exhibit to the Revised Draft Registration Statement.

Risks Relating to Our ADSs and This Offering
Our dual-class structure with different voting rights will limit your ability
to influence
corporate matters...., page 53
10. We note your disclosure that each Class B ordinary share will be entitled
to six votes. Please expand your
    disclosure to discuss the risk that future issuance of Class B shares may
be dilutive to holders of Class A
    shares and that your dual-class structure may render your shares ineligible
for inclusion in certain stock
    market indices and the potential impact on the market price and liquidity
of your ordinary shares.
     The Company has revised the disclosure on page 54 of the Revised Draft
Registration Statement in response
     to the Staff's comment.

Use of Proceeds, page 58
11. Please revise the discussion to disclose the estimated net amount of the
proceeds broken down into each
    principal intended use, (i) research and development of our early cancer
detection technologies,
    (ii) obtaining NMPA approvals for additional cancer genotyping products,
including completing related
    clinical trials; and (iii) other general and administrative matters. If the
anticipated proceeds will not be
    sufficient to fund all the proposed purposes, please disclose the order of
priority of such purposes. To the
    extent material amounts of other funds are necessary to accomplish the
specified purposes, state the
    amounts and sources of such other funds needed for each specified purpose.
Refer to Item 3.C.1 of Form
    20-F.
     The Company has revised the disclosure on page 58 of the Revised Draft
Registration Statement in response
     to the Staff's comment. The Company respectfully advises the Staff that
while the sufficiency of the net
     proceeds of the offering will depend on the size of the offering, the
Company currently anticipates that the net
     proceeds will be sufficient for all the proposed purposes.

Capitalization, page 60
 12. We note on pages F-24 and F-36 that all of your outstanding preferred
shares will convert automatically
    into ordinary shares in the event of a "Qualified IPO". Please revise your
disclosures to clarify all of the
    stipulations of a "Qualified IPO" and explain why you believe that it is
factually supportable that the
    outstanding preferred shares will automatically convert into ordinary
shares.
     The Company respectfully advises the Staff that, pursuant to the Company's
seventh amended and restated
     memorandum and articles of association and fourth amended and restated
shareholders' agreement
     (collectively, the "Corporate Documents"), which were filed as Exhibit 3.1
and Exhibit 4.4 to the Draft
     Registration Statement, all preferred shares shall automatically be
converted into fully-paid and non-
     assessable ordinary shares upon the closing of a Qualified IPO. A
"Qualified IPO" refers to the closing of a
     firm commitment underwritten initial public offering of the ordinary
shares (or securities representing
     ordinary shares) on a recognized exchange which meets the following
requirements: (i) such closing shall take
     place on or prior to the third (3rd) anniversary of the original Series C
issue date (i.e. January 31, 2019),
     (ii) the pre-offering valuation of the Company shall be at least
US$1,442,496,338; and (iii) the post-offering
     public float shall not be less than 10% of the total issued capital of the
Company.

Securities and Exchange Commission
December 9, 2019
Page 7 of 11

     The Company further advises the Staff that pursuant to the Corporate
Documents, the requirement of
     Qualified IPO can be waived by the Company's shareholders without
triggering any valuation adjustment
     mechanism. In the event that this offering does not meet the requirement
of a "Qualified IPO", the Company
     expects its shareholders to waive such requirement so that all preferred
shares will nonetheless be
     automatically converted into ordinary shares without any adverse impact on
the Company's financials. As
     such, the Company does not believe that the stipulations of a "Qualified
IPO" are meaningful disclosures for
     investors.

Management's Discussion and Analysis of Financial Condition and Results of
Operations
Key Components of Results of Operations
Operating Expenses
Selling and Marketing Expenses , page 76
13. We note your disclosure that selling and marketing expenses primarily
consist of staff costs for personnel
    engaged in sales and marketing functions, travel and entertainment expenses
and convention expenses.
    We further note your disclosure on page 80 that your selling and marketing
expenses as a percentage of
    total revenues decreased in 2018 primarily due to economies of scale.
Please expand your disclosure to
    discuss your compensation structure with your sales force. Refer to Item
5.A of Form 20-F. Additionally,
    please reconcile the description of selling and marketing expenses with
your statement on page 80 that
    your general and administrative expenses increased in 2018 in part due to
an increase in travel and
    entertainment expenses.
     The Company respectfully advises the Staff that its selling and marketing
expenses primarily consist of staff
     costs for its sales and marketing personnel. Such staff costs are
comprised of (i) fixed base salary (which
     accounted for 83%, 77% and 76% of total staff costs for sales and
marketing personnel in 2017, 2018 and the
     nine months ended September 30, 2019, respectively), and (ii)
performance-based bonuses linked to the
     Company's growth, which is determined by certain key-performance
indicators such as annual sales
     volume. As the vast majority of such staff costs is fixed, the growth of
the Company's revenues from 2017 to
     2018 outpaced the growth of such staff costs (i.e. increased economies of
scale), which resulted in a decrease
     of selling and marketing expenses as a percentage of revenues.
     The Company has revised the disclosure on pages 77 and 83 of the Revised
Draft Registration Statement in
     response to the Staff's comment.

Fair Value of Share Options, page 88
 14. We note that the estimated fair market value per ordinary share is a
significant assumption in your share
    option grant valuation. Accordingly, please bridge for us the fair value
per share determinations used for
    each option grant subsequent to December 31, 2018 to the current estimated
IPO price per share. We will
    delay our assessment of your response pending inclusion of the estimated
IPO price in the filing.
     In response to the Staff's comment, the Company has revised the disclosure
on page 92 of the Revised Draft
     Registration Statement to include the assumptions used to estimate the
fair value of the share options granted
     in the nine months ended September 30, 2019. The Company acknowledges the
Staff's request to bridge the
     fair value per share determination used for each option grant subsequent
to December 31, 2018 to the
     estimated IPO price per share, and will supplementally provide the
requested information to the Staff when the
     estimated IPO price range becomes available.

Business
Overview, page 106
15. With respect to your early detection technologies, please briefly explain
what you mean by "specificities
    of 96%." Similarly, please revise the graphics and expand your disclosure
as appropriate on page 112 to
    provide appropriate context for an investor to evaluate the graphics.
Please also briefly explain what you
    mean by a "capture-based" fully automated NGS library preparation system on
page 106. Additionally,
    please revise your statement on page 123 that the testing success rate of
your LungPlasma is 99.5%, on
    par with worldclass genomic testing companies to indicate how testing
success rate is measured and the
    basis for your competitive claim.
     The Company has revised the disclosure on pages 110, 118, 119 and 129 of
the Revised Draft Registration
     Statement in response to the Staff's comment. The Company respectfully
advises the Staff that:
         (i) As disclosed on page 6 of the Revised Draft Registration Statement
under "Conventions that apply to
             this prospectus", "specificity" refers to the percentage of people
who test negative for a specific
             disease or condition among people who do not have the disease or
condition.
         (ii) "Capture-based" enrichment method is one of the two major
enrichment methods widely used for
              targeted DNA sequencing, where probe is used to "capture"
specific genomic regions of interest for
              downstream sequencing. The other widely used method for targeted
DNA sequencing is "amplicon-
              based" method where specific genomic regions are enriched by
being amplified using primers around
              both ends of such regions.
         (iii) LungPlasmaTM' s testing success rate of 99.5% is calculated by
dividing (x) number of clinical
               samples tested by LungPlasma that passed the Company's QC
standards, including cfDNA extraction
               amount, pre-library quality, library quality and sequencing data
quality (7,443 samples), by (y) total
               number of clinical samples tested by LungPlasmaTM (7,403
samples) in 2019. The Company believes
               that such testing success rate is on par with world-class
genomic testing companies, such as Guardant
               Health (Nasdaq:GH), who reported a "test success rate of 99.6%"
for Guardant360, the marketing
               leading comprehensive liquid biopsy test, in its annual report
on Form 10-K filed on March 19, 2019.

material patents, please clearly
    disclose:
         applicable jurisdictions where patents are issued or where patent
applications are pending;
         type of patent protection (e.g. composition of matter, use, or

          the specific NGS-based cancer genotyping test or technology to which
the patent relates and the
          patent expiration date or expected expiration date for patent
application.
     The Company has revised the disclosure on pages 130 and 131 of the Revised
Draft Registration Statement in
     response to the Staff's comment.

Note 1. Organization and Basis of Presentation , page F-10
17. We note here and throughout the filing that you consolidate Burning Rock
(Beijing) Biotechnology Co.,
    Ltd. ("VIE") and the VIE's subsidiaries within your financial statements as
of each balance sheet date
    and that those VIE agreements were amended on October 21, 2019. Please
revise the filing to disclose the
    process by which you formed the VIE structure, including relevant
chronological dates. Also, revise the
    filing to explain why you are consolidating this VIE and the VIE's
subsidiaries as of each balance sheet
    date and how the amended agreements signed on October 21, 2019 impacted
your consolidation
    conclusions.
     In response to the Staff's comment, the Company has revised the disclosure
on pages F-10 to F-13 of the
     Revised Draft Registration Statement to explain why the Company is
consolidating the VIE and its
     subsidiaries as of each balance sheet date and the impact of the amended
agreements signed on October 21,
     2019 on its consolidation conclusions.

Note 2. Summary of Significant Accounting Policies
Revenue Recognition
Revenue from central laboratory business, page F-20
18. We note that when you are expected to be entitled to a breakage amount, it
is recognized as revenue in
    proportion to the pattern of rights exercised by the patient. Please revise
the filing to explain how you
    estimate breakage in these situations and the significant judgments
underlying those estimates. Refer to
    ASC 606-10-50-17.
     In response to the Staff's comment, the Company has revised the disclosure
on pages 90, 91, F-20 and F-21 of
     the Revised Draft Registration Statement to explain how the Company
estimates breakage in these situations
     and the significant judgments underlying those estimates.

Securities and Exchange Commission

Revenue from in-hospital business, page F-21
19. We note that you recognize revenue on a net basis related to the provision
of the facilitation services for
    the laboratory equipment sales to hospitals since you have determined that
you are an agent. We also
    note that you purchase this laboratory equipment from third-party suppliers
when the hospital makes a
    purchase request and resell the laboratory equipment to the hospital.
Please explain in more detail how
    you have considered all of the requirements in ASC 606-10-55-36 through
55-40 to conclude that you are
    the agent in these transactions.
     The Company respectfully advises the Staff that the Company's performance
obligation is to facilitate the
     hospitals and third-party suppliers to complete the purchase of laboratory
equipment, which is not controlled
     by the Company prior to being transferred to the hospitals. The
third-party suppliers are responsible for the
     installation of the laboratory equipment at the hospitals prior to
acceptance. The third-party suppliers are also
     responsible for the maintenance of the laboratory equipment at their cost
during the warranty period.
     Therefore, the Company concluded that it was not the principal based on
the criteria in ASC 606-10-55-37A
     as it does not control the laboratory equipment before it is transferred
to the hospital nor have the rights to
     direct the installation or maintenance services provided to the hospitals.
Further, the Company did not meet
     the principal indicators in ASC 606-10-55-39 (a) and subparagraph 55-39
(b) as it was not primarily
      responsible for fulfilling the promise to provide the specified
laboratory equipment to the hospitals, nor did it
     bear inventory risk before the specified laboratory equipment is
transferred to the hospitals. While the
     Company has some discretion in establishing the price the customer pays
for the specified goods or services,
     this indicator alone does not provide persuasive evidence that the Company
controls the goods or services
     prior to transfer to the customer.


20. Please revise the filing to disclose if you have any warranty obligations
or customer rights of return from
    the sales of reagent kits to hospitals. Refer to ASC 606-10-55-22 thru
55-35.
     In response to the Staff's comment, the Company has revised the disclosure
on page F-21 of the Revised Draft
     Registration Statement to disclose that it has no customer rights of
return from the sales of reagent kits to
     hospitals other than for defective products.

General
21. Please provide us proofs of all graphics, visual, or photographic
information you will provide in the
    printed prospectus prior to its use, for example in a preliminary
prospectus. Please note that we may
    have comments regarding this material.
     The Staff's comment is duly noted. The Company will provide the Staff with
proofs of all graphics, visual, or
     photographic information the Company intends to include in the printed
prospectus as soon as it becomes
     available and prior to its use.
