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

     It is suggested that this management's discussion be read in
conjunction with the management discussion included in the
Registrant's annual report for the fiscal year ended December 31,
1995, previously filed with the Securities and Exchange
Commission.

COMPARISON OF THE THREE MONTHS ENDED SEPTEMBER 30, 1996 AND SEPTEMBER 30, 1995

     Ostex International, Inc. (the "Company") had revenues of
$1,859,000 for the quarter ended September 30, 1996, compared to
$717,000 for the quarter ended September 30, 1995.  Research and
development fees amounted to $1,083,000 during the 1996 third
quarter, including two milestone payments totaling $1,080,000
from Mochida Pharmaceutical Co., Ltd. ("Mochida").  Third quarter
1995 research and development fees totaled $429,000 which
included milestone payments of $405,000 from Mochida.

     On May 8, 1995 the Company's lead product, the 
Osteomark-Registered Trademark- test, first became commercially 
available in the United States as a urinary assay that provides 
a quantitative measure of the excretion of cross-linked 
N-telopeptides of type I collagen (NTx)as an indicator of human bone 
resorption.  Prior to becoming commercially available, the Osteomark 
test was not available in the U.S. except for research purposes only.  
Revenues from product sales and research testing services for 
the quarter ended September 30, 1996 were $776,000, compared to 
$288,000 for the quarter ended September 30, 1995. The increase 
in 1996 is attributable to higher volumes of kits sold to
laboratories and distributors worldwide during the quarter.
During the third quarter of 1996, worldwide sales were $776,000
compared to $224,000 in the same period of 1995 while research
testing decreased from $64,000 in 1995 to zero in 1996. There
were no research testing services sales during the 1996 quarter
due to the completion of an existing contract in December 1995.

     The Company's cost of products sold totaled $247,000 for the
quarter ended September 30, 1996 compared to $101,000 for the
same period of 1995.  The gross profit rate on product sales for
the 1996 third quarter was 68% compared to 55% for the third
quarter in 1995.  The change in gross profit rate is a result of an 
increase in the Company's average selling price as well as a 
decline in unit manufacturing costs resulting from increased 
production volume that caused fixed manufacturing costs to be 
spread over the higher number of units produced during the 
third quarter 1996. 

     The Company's research and development expenditures totaled
$757,000 for the quarter ended September 30, 1996, compared to
$869,000 for the quarter ended September 30, 1995.  The decrease
is due primarily to the completion of one of the Company's
clinical trials in November 1995.

     



     Selling, general and administrative expenses totaled
$2,328,000 for the quarter ended September 30, 1996, compared to
$1,769,000 for the same period ended September 30, 1995.  The
higher expense level during the three months ended September 30,
1996 was due to the implementation of marketing programs to
support Osteomark in the U.S., the addition of sales personnel to
support in these efforts, increased legal costs involved with the
arbitration hearing with Boehringer Mannheim, and patent
litigation.

     Interest income totaled $299,000 for the quarter ended
September 30, 1996, compared to $466,000 for the three month
period ended September 30, 1995.  The decrease is due to lower
invested balances resulting from using cash to fund the Company's
operating losses.

     Interest expense totaled $23,000 for the quarter ended
September 30, 1996, compared to zero for the three month period
ended September 30, 1995.  Interest expense is attributed to the
Company entering into a note agreement in the amount of $746,000
that provided funds required for expansion of manufacturing and
administrative facilities during 1995 and 1996.


COMPARISON OF THE NINE MONTHS ENDED SEPTEMBER 30, 1996 AND SEPTEMBER 30, 1995

     The Company had revenues of $3,300,000 for the nine month
period ended September 30, 1996, compared to $2,156,000 for the
nine month period ended September 30, 1995.  Research and
development fees amounted to $1,083,000 during the first nine
months of 1996, compared to $1,033,000 in the first nine months
of 1995.  The 1996 period included fees of $1,080,000 from
Mochida for attainment of two milestones under a research and
development agreement.  The 1995 period included $500,000 from
Johnson & Johnson Clinical Diagnostics and $495,000 from Mochida.
Higher volumes of kits sold worldwide resulted in $2,217,000 of
product revenues for the nine month period ended September 30,
1996, compared to $911,000 for same period in 1995.  Research
testing services decreased from $212,000 in 1995 to zero in 1996
due to the completion of an existing contract in December 1995.

     The Company's cost of products sold totaled $682,000 for the
nine month period ended September 30, 1996, compared to $424,000
for the nine months ended September 30, 1995.  The gross profit
rate on product sales for the nine months ended September 30,
1996 was 69% compared to 53% for the same period in 1995. The change
in gross profit rate is a result of an increase in the Company's 
average selling price as well as a decline in unit manufacturing 
costs resulting from increased production volume that caused fixed 
manufacturing costs to be spread over the higher number of units 
produced during the during nine months ended September 30, 1996.
                                                                
     The Company's research and development expenditures totaled
$2,203,000 for the nine month period ended September 30, 1996,
compared to $2,485,000 for the same period ended September 30,
1995.  The decrease is due primarily to a decline in expenses
associated with the completion of one of the Company's clinical
trials in November 1995.

     Selling, general and administrative expenses totaled
$6,695,000 for the nine month period ended September 30, 1996,
compared to $4,192,000 for the nine months ended September 30,
1995.  The higher expense level was due to the implementation of
marketing programs to support Osteomark in the U.S., the addition
of sales personnel to support in these efforts, increased legal
costs involved with the arbitration hearing with Boehringer
Mannheim, and patent litigation.

     Interest income totaled $1,036,000 for the nine month period
ended September 30, 1996, compared to $1,259,000 for the same
period ended September 30, 1995.  The decrease is due to lower
invested balances resulting from using cash to fund the Company's
operating losses.

     Interest expense totaled $23,000 for the nine month period
ended September 30, 1996, compared to zero for the nine month
period ended September 30, 1995.  Interest expense is attributed
to the Company entering into a note agreement in the amount of
$746,000 that provided funds required for expansion of
manufacturing and administrative facilities during 1995 and 1996.






LIQUIDITY AND CAPITAL RESOURCES

     The Company has financed its operations from inception
primarily through three private placements of preferred stock
aggregating approximately $12,800,000 and an initial public
offering of 3,645,642 shares of common stock, which generated net
proceeds of approximately $32,000,000.  Additional funds of
approximately $11,900,000 have been generated through
collaborative research and licensing agreements, sales of the
Osteomark immunoassay kits and research testing services.  As of
September 30, 1996, the Company had $22,341,000 in cash and cash
equivalents and short-term investments, working capital of
$23,677,000 and total shareholder' equity of $26,174,000.

     During the nine month period ended September 30, 1996 the
Company used $5,786,000 of cash for operating activities as
compared to $3,743,000 during the nine month period ended
September 30, 1995.  The primary reason for the change was the
increased net loss.  During the nine month period ending
September 30, 1996 the Company entered into a note agreement in
the amount of $746,000 that provided funds required for expansion
of manufacturing and administrative facilities during 1995 and
1996.  Monthly payments will be made against the principal balance 
and interest for a period of four years. 

     The Company's future capital requirements depend upon many 
factors, including effective commercialization activities and 
arrangements, continued scientific progress in its research and 
development programs, progress toward development of the O-CSF
technology, which potentially has therapeutic uses, the costs
involved in filing, prosecuting and enforcing patent claims, the
costs involved in legal efforts to enforce patent rights and
distribution contracts, and the time and costs involved in
obtaining regulatory approvals.  Additional funds from equity or 
debt financing may be required.  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 at least mid 1998.
     
     Forward looking statements in this Form 10-Q involve a number
of risks and uncertainties including, but not limited to, level
of product sales, pricing, market acceptance, changing economic
conditions, risks in product and technology development, the
effect of the Company's accounting policies and other risk
factors detailed in the Company's SEC filings.


                   PART II - OTHER INFORMATION
                                
                                
ITEM 1.   LEGAL PROCEEDINGS

     In October 1994, the Company and Boehringer Mannheim, a
division of  Corange International, Ltd, executed a license
agreement  which granted to Boehringer Mannheim a co-exclusive,
10-year license  for worldwide distribution of Osteomark kits in
the existing microtiter plate (MTP) format, except in countries
where the Company has prior exclusive   distribution
agreements.   Additionally, Boehringer Mannheim  was granted a
co-exclusive, 10-year license to adapt the Osteomark test for
use on automated systems and to manufacture and market it
worldwide, except in Japan.

     On  August 25, 1995, the Company  filed an action in the
United States District Court for the Western District of
Washington  (the "District  Court") to compel Boehringer Mannheim
to participate in arbitration and to enforce any arbitrated award
of damages or other relief.  The Company believes that
Boehringer Mannheim concentrated its  efforts on adapting the
Company's Osteomark test for use on Boehringer Mannheim's
proprietary, automated instruments,  but  has failed to meet
its marketing and other obligations under the agreement for
the distribution of the Osteomark test in the existing,
Company-manufactured MTP format.  On October 26, 1995,
Boehringer Mannheim filed an answer in the District Court,







denying that requisites to arbitration under the agreement have
been met, counterclaiming for damages against the Company
for breach of contract, and requesting that the Company's
motion to compel arbitration be denied, or, in the alternative,
that the parties  be compelled to mediate their disputes
as a prerequisite to arbitration.
     
     On December 5, 1995 a United States District Court judge
ruled against Boehringer Mannheim and ordered it to proceed
with the arbitration.   The federal court retained
jurisdiction over the dispute to enforce any award issued
by the  arbitrators.  The hearing before a panel of the American 
Arbitration Association was held in Seattle on September 3-11, 1996.  
Post-trial briefs  are scheduled for filing during November, 1996, and a
decision by the arbitrators is expected at the end of
1996. At the present time management cannot estimate the amount of 
damages, if any, which may be awarded to either party.

     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 biotechnology company based in
Denmark, and Diagnostic Systems Laboratories Inc. for patent
infringement. The Company believes Osteometer's Crosslaps immunoassay
incorporates technology that infringes  on  Company
technology protected by the United States Letters Patent No.
5,455,179.   In September 1996 the defendants filed a response
denying infringement and counterclaimed that the subject
patent is invalid and unenforceable.  The Company expects the case 
will be scheduled for trial in early 1998. At the present time management
cannot estimate the amount of damages, if any, which may be
awarded to either party.

                     NOTES TO 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 period, 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, 1995.


Net Loss per Common and Common Equivalent Share

For the three months ended September 30, 1996, and the nine
months ended September 30, 1996, 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 or warrants.  These shares are not
included in the computation of net loss per share because the
effect of including such shares would be antidilutive.


2.  RELATED PARTY TRANSACTIONS


Legal and Consulting Services

Total operating expenses include legal and consulting fees for
services provided by a related party totaling $96,000 and
$167,000 for the quarters ended September 1996 and 1995,
respectively, and $170,000 and $312,000 for the nine months
ended September 1996 and 1995, respectively.
