ITEM 2.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
           RESULTS OF OPERATIONS

         This Quarterly Report on Form 10-Q contains forward-looking  statements
which  reflect the  Company's  current  views with respect to future  events and
financial performance.  These forward-looking  statements are subject to certain
risks and  uncertainties,  including  those  discussed  below,  that could cause
actual  results  to  differ   materially  from   historical   results  or  those
anticipated.  Words used herein such as  "believes,"  "anticipates,"  "expects,"
"intends,"  and similar  expressions  are  intended to identify  forward-looking
statements but are not the exclusive means of identifying  such  statements.  In
addition,  the  disclosures  under the caption  "Other  Factors  that May Affect
Operating Results", consist principally of a brief discussion of risks which may
affect  future  results  and are thus,  in their  entirety,  forward-looking  in
nature.  Readers  are  urged  to  carefully  review  and  consider  the  various
disclosures  made by the  Company  in this  report  and in the  Company's  other
reports  previously  filed with the  Securities  and  Exchange  Commission  (the
"SEC"),  including the Company's  Annual Report on Form 10-K for the fiscal year
ended December 31, 1996, that attempt to advise interested  parties of the risks
and factors that may affect the Company's business.

COMPARISON OF THE THREE MONTHS ENDED SEPTEMBER 30, 1997 AND SEPTEMBER 30, 1996

       Total revenues were  $1,505,000 for the quarter ended September 30, 1997,
compared to $1,859,000 for the quarter ended  September 30, 1996.  Product sales
were $1,055,000 during the three month period ended September 30, 1997, compared
to  $776,000  for the same period in 1996.  The 36 % increase  was due to higher
volumes  of  OSTEOMARK-registered trademark- kits  sold  to  domestic   
laboratories and foreign  distributors  during the 1997 quarter compared to
the same period of 1996. License and research and development fees were $450,000
during the three month period ended  September 30, 1997,  compared to $1,083,000
during the same period in 1996. The $633,000  reduction in fees collected  under
license and research and development agreements with Mochida Pharmaceutical Ltd.
("Mochida") was expected and is due to attainment of scheduled  milestones.  The
Company  does not expect to receive any  further  milestone  payments  under the
license  agreement with Mochida and future  payments of up to $750,000 under the
research and  development  agreement are contingent  upon Mochida's  decision to
exercise  its option to license the NTx serum assay and  achievement  of certain
serum assay development milestones.

       The  Company's  cost of products  sold  totaled  $228,000 for the quarter
ended September 30, 1997,  compared to $247,000 for the same period of 1996. The
decrease was primarily due to elimination of excess facility costs.  The cost of
products  sold  decreased  as a percentage  of product  sales to 22% in the 1997
third  quarter  compared to 32% in the 1996 third  quarter due to a reduction in
unit  manufacturing  costs resulting from increased  production  volume allowing
fixed  manufacturing  costs to be spread  over a higher  base of units  produced
during the quarter  ended  September  30,  1997,  compared to the same period in
1996.

       The Company's  research and development  expenditures  totaled $1,090,000
for the quarter ended  September 30, 1997,  compared to $757,000 for the quarter
ended  September 30, 1996. The $333,000  increase was primarily  attributable to
the NTx assay point-of-care development programs with Metrika Laboratories, Inc.
("Metrika") and Hologic, Inc. ("Hologic"). In addition, research and development
expenses  increased due to the cost of clinical studies  commenced at the end of
1996 and during the first quarter 1997. Included in the Company's studies in the
1997  quarter  was a study  for the  determination  of  variability  and the NTx
reference  range in males,  a study  for  variability  of NTx in  postmenopausal
women, and a study for the use of the Osteomark test in helping to identify bone
metastases.



       Selling,  general and administrative  expenses totaled $1,903,000 for the
quarter  ended  September 30, 1997,  compared to $2,328,000  for the three month
period ended  September  30, 1996.  The $425,000  decrease was  primarily due to
completion of the Company's free testing program in 1996 and the completion of a
hearing before the American Arbitration  Association against Boehringer Mannheim
in  September  1996,  partially  offset  by  increased  costs of  litigation  in
connection  with the Osteometer and C.R. Bard cases (see "Legal  Proceedings" in
Part II, Item 1 of this 10-Q). The Company anticipates a substantial increase in
legal expenses in connection  with the Osteometer  patent  infringement  lawsuit
during the fourth  quarter of 1997 as the proceeding  enters a discovery  phase,
and continuing into fiscal year 1998.

       Interest  income  totaled  $196,000 for the quarter  ended  September 30,
1997,  compared to $299,000  for the  quarter  ended  September  30,  1996.  The
decrease is due to lower invested balances resulting from using cash to fund the
Company's operating losses.


COMPARISON OF THE NINE MONTHS ENDED SEPTEMBER 30, 1997 AND SEPTEMBER 30, 1996

       Total revenues were  $3,108,000 for the nine month period ended September
30, 1997,  compared to $3,300,000 for the nine month period ended  September 30,
1996. Product sales were $2,658,000 during the nine month period ended September
30, 1997,  compared to $2,217,000 for the same period in 1996. The 20 % increase
was due to higher  volumes of Osteomark kits sold to domestic  laboratories  and
foreign distributors during the 1997 period compared to the same period of 1996.
License and research and  development  fees were $450,000  during the nine month
period ended September 30, 1997,  compared to $1,083,000  during the same period
in 1996.  The  reduction  in fees  collected  under  license  and  research  and
development  agreements  with Mochida was expected and is due to  attainment  of
scheduled  milestones.  The  Company  does not  expect to  receive  any  further
milestone  payments under the license agreement with Mochida and future payments
of up to $750,000  under the research and  development  agreement are contingent
upon  Mochida's  decision to exercise  its option to license the NTx serum assay
and achievement of certain serum assay development milestones.

       The Company's  cost of products sold totaled  $640,000 for the nine month
period ended September 30, 1997,  compared to $682,000 for the nine months ended
September  30, 1996.  The decrease  was  primarily  due to a reduction of excess
facility  costs.  The cost of products sold decreased as a percentage of product
sales to 24% in the 1997  period  compared  to 31% in the 1996  period  due to a
reduction in unit manufacturing costs resulting from increased production volume
allowing  fixed  manufacturing  costs to be spread  over a higher  base of units
produced during the nine months ended  September 30, 1997,  compared to the same
period in 1996.

       The Company's  research and development  expenditures  totaled $3,522,000
for the nine month period ended  September 30, 1997,  compared to $2,203,000 for
the nine months ended  September 30, 1996.  The increase of $1,319,000 is due to
research spending in connection with the development of NTx assay  point-of-care
devices  under the  development  agreements  with Metrika and Hologic  discussed
above, as well as funding of research conducted at the University of Washington.
Research at the  University  of  Washington  is focused on molecular  markers of
connective tissue degradation,  and on developing a further understanding of the
osteoclast colony stimulating factor ("O-CSF") as a potential therapeutic agent.
This  research  funding is expected  to  continue  through  1999.  In  addition,
research and development  expenses increased due to the cost of clinical studies
commenced at the end of 1996 and during the first quarter 1997.

       Selling,  general and administrative  expenses totaled $5,688,000 for the
nine month period ended September 30, 1997,  compared to $6,695,000 for the nine
months  ended  September  30,  1996.  The  lower  expense  level  was due to the
completion  of a hearing  before the American  Arbitration  Association  against
Boehringer  Mannheim in September 1996 (see "Legal Proceedings" in Part II, Item
1 of this 10-Q),  and the  completion of the Company's  free testing  program in
1996.  However,  the  decrease  was  partially  offset  by  increased  costs  of
litigation in  connection  with the  Osteometer  and C.R. Bard cases (see "Legal
Proceedings" in Part II, Item 1 of this 10-Q). As discussed  above,  legal costs
associated  with the  Osteometer  patent  infringement  lawsuit are  expected to
increase substantially in the fourth quarter 1997, and continue into fiscal year
1998.



       Interest  income  totaled  $675,000  for  the  nine  month  period  ended
September  30, 1997,  compared to  $1,036,000  for the same period in 1996.  The
decrease is due to lower invested balances resulting from using cash to fund the
Company's operating losses.


LIQUIDITY AND CAPITAL RESOURCES

       As of September 30, 1997,  the Company had  $14,178,000  in cash and cash
equivalents and short-term investments, working capital of $14,214,000 and total
shareholders'  equity of $17,635,000.  As a result of funding  operating  losses
during the nine months ended  September 30, 1997,  cash,  cash  equivalents  and
short-term  investments  decreased by $7,051,000,  working capital  decreased by
$6,687,000 and  shareholders  equity  decreased by  $5,891,000.  During the nine
month  period  ended  September  30, 1997 the Company  purchased  $1,093,000  in
property and equipment, received $124,000 from the exercise of stock options and
paid $121,000 of notes payable.

         In October  1997,  the Company  received  $6,200,000  in  settlement of
certain  litigation  (see "Legal  Proceedings" in Part II, Item 1 of this 10-Q).
The Company did not reflect the settlement in its balance sheet at September 30,
1997.  This will be  reflected  in income and assets  during the quarter  ending
December 31, 1997.

         The Company's  future  capital  requirements  depend upon many factors,
including effective commercialization activities and collaborative arrangements,
continued  progress in its research and  development  programs,  progress toward
development of the O-CSF technology,  the costs involved in filing,  prosecuting
and  enforcing  patent  claims,  and the time and costs  involved  in  obtaining
regulatory  approvals.  The Company may require  additional funds from equity or
debt  financings.  There can be no assurance that such additional  funds will be
available on favorable  terms, if at all.  Because of the Company's  significant
long-term  cash  requirements,  it may  seek  to  raise  additional  capital  if
conditions in the public equity markets are favorable,  even if the Company does
not have an  immediate  need for  additional  cash at that time.  If  additional
financing is not available,  the Company anticipates that its existing available
cash,  its future  license and research  revenues  from  existing  collaboration
agreements,  product sales and interest income from short-term  investments will
be adequate to satisfy its capital  requirements and to fund operations  through
mid 1999.  No assurance can be given,  however,  that such funds will in fact be
adequate until that time, since the Company's  prediction is subject to a number
of  risks  and  uncertainties,   including  those  discussed  in  the  following
paragraph.

OTHER FACTORS THAT MAY AFFECT OPERATING RESULTS

         The  Company's  operating  results  may  fluctuate  due to a number  of
factors  including,  but not  limited  to,  volume and timing of product  sales,
product pricing, market acceptance of the Company's products,  changing economic
conditions in the healthcare industry, delays and increased costs of product and
technology   development,   the  Company's   ability  to  develop  and  maintain
collaborative  arrangements,  the outcome of  litigation,  and the effect of the
Company's  accounting  policies,  as well as other risk factors  detailed in the
Company's 1996 Form 10-K and other SEC filings. All of the foregoing factors are
difficult  for the Company to predict and can  materially  adversely  affect the
Company's business and operating results.


                          PART II -- OTHER INFORMATION


ITEM 1.    LEGAL PROCEEDINGS

       On November 4, 1997, the Company  announced  settlement  with  Boehringer
Mannheim under which the Company received a lump sum payment of $6,200,000.  The
settlement  between  the two  parties is the result of the  previously  reported
January 28, 1997 ruling by the American  Arbitration  Association  in connection
with the Company's claims against Boehringer Mannheim.



       In June 1996,  the Company filed an action in the United States  District
Court for the Western District of Washington  against  Osteometer Biotech A/S, a
medical  technology  company  based in Denmark  ("Osteometer"),  and  Diagnostic
Systems  Laboratories  Inc. for patent  infringement of United States Patent No.
5,455,179.   The  Company  believes  Osteometer's  bone  resorption  immunoassay
incorporates technology which infringes patented Ostex technology.  In September
1996, the defendants  filed a response denying  infringement and  counterclaimed
that Ostex'  patent is invalid and  unenforceable.  By order dated July 7, 1997,
the Court granted  Ostex's  motion to file a  supplemental  complaint,  to add a
second  cause of action based upon United  States  Patent No.  5,641,837,  which
issued on June 24, 1997. On October 24, 1997, Ostex filed a second  supplemental
complaint to add third and fourth  causes of action  based upon U.S.  Patent No.
5,652,112,  which issued on July 29, 1997, and U.S. Patent No. 5,656,439,  which
issued  on August  12,  1997.  The  lawsuit  is  currently  scheduled  for trial
commencing  June 30, 1998.  At the present time  management  cannot  predict the
outcome  of the  lawsuit  but  intends  to  continue  to  vigorously  assert its
position.

       On April 9, 1997,  the  Company  was served  with a lawsuit  filed in the
United  States  District  Court,  Central  District of  California  by C.R. Bard
("Bard").  The complaint  alleges that Ostex' Osteomark  product  infringes U.S.
Patent No.  4,628,027  assigned to Bard in 1993.  Management  believes that this
suit is without merit and that Ostex' Osteomark product falls outside the claims
of the subject patent.

                     NOTES TO CONDENSED FINANCIAL STATEMENTS



1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:


Basis of Presentation

The  unaudited  condensed  financial  statements  include the  accounts of Ostex
International,  Inc. (a Washington corporation) (the "Company"). These financial
statements have been prepared in accordance with generally  accepted  accounting
principles  for  interim  financial  reporting  and  pursuant  to the  rules and
regulations of the Securities and Exchange  Commission.  While these  statements
reflect  all  normal  recurring   adjustments  which  are,  in  the  opinion  of
management,  necessary  for fair  presentation  of the  results  of the  interim
periods,  they do not include all of the information  and footnotes  required by
generally accepted accounting principles for complete financial statements.  For
further  information,  refer to the financial  statements and footnotes  thereto
included in the  Company's  Annual  Report filed on Form 10-K for the year ended
December 31, 1996.


Net Loss per Common and Common Equivalent Share

For the three and nine months ended September  30,1997,  net loss per common and
common  equivalent  share was  based on the  weighted  average  number of common
shares outstanding during each period.  Common stock equivalents  include shares
issuable upon the exercise of outstanding  stock  options.  These shares are not
included  in the  computation  of net loss  per  share  because  the  effect  of
including such shares would be antidilutive.


2.  CONTINGENCIES


Legal Proceedings

Refer to Part II, Item 1 of this Form 10-Q.


3.  NEW ACCOUNTING PRONOUNCEMENTS


In February 1997, the Financial  Accounting  Standards Board issued Statement of
Financial  Accounting Standards No. 128, Earnings Per Share (SFAS 128), which is
effective for periods  beginning  after December 15, 1997.  SFAS 128 establishes
new  standards  for  computing  and  presenting  earnings per share (EPS).  Upon
adoption of SFAS 128, companies will report basic EPS and diluted EPS instead of
previously reported primary and fully diluted EPS. Under the new standard,  both
the Company's  basic and diluted EPS for the quarter  ended  September 30, 1997,
would be a net loss per share of $.12,  and for the nine months ended  September
30, 1997, both basic and diluted EPS would be a net loss per share of $.49.


4.  SUBSEQUENT EVENTS


         In October  1997,  the Company  received  $6,200,000  in  settlement of
certain  litigation  (see "Legal  Proceedings" in Part II, Item 1 of this 10-Q).
The Company did not reflect the settlement in its balance sheet at September 30,
1997.  This will be  reflected  in income and assets  during the quarter  ending
December 31, 1997.
