                  PART I - FINANCIAL INFORMATION


ITEM 1.   FINANCIAL STATEMENTS

     Attached hereto are the Registrant's unaudited condensed balance sheet as
of March 31, 1996, the audited condensed balance sheet as of December 31, 1995,
and the unaudited condensed statements of operations and cash flows for the
three month period ended March 31, 1996 and 1995.  Also attached are notes to
the unaudited financial statements.


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 to
shareholders for the fiscal year ended December 31, 1995, previously filed 
with the Securities and Exchange Commission.

COMPARISON OF THE THREE MONTHS ENDED MARCH 31, 1996 AND MARCH 31, 1995

     Ostex International, Inc. (the  Company ) had revenues of $587,000 for
the three month period ended March 31, 1996, compared to $380,000 for the
three month period ended March 31, 1995.  On May 8, 1995 the Food and Drug
Administration (FDA) cleared the Company's Osteomark-Registered Trademark
immunoassay for commercial sale in the United States.  The Company 
anticipates that in light of the FDA's product clearance, sales to 
laboratories and physicians in the U.S. may increase in ensuing quarters.  The
Company expects to incur significant expense to stimulate product sales in the
U.S. and Europe. Prior to receiving clearance from the FDA, the Osteomark test
was not available in the U.S. except for research purposes only.

     Product sales for the three month period ended March 31, 1996 were 
$587,000 compared to $366,000 for the three month period ended March 31, 1995.
The increase in 1996 is attributable to higher volumes of kits sold in the 
U.S., Europe, and Canada during the quarter.  During the first quarter of 1996,
domestic and European sales were $587,000 compared to $291,000 in the same
period of 1995 and research testing decreased from $75,000 in 1995 to zero in
1996. There were no research testing services sales during the quarter due to
the completion of an existing contract in December 1995, and the continuing
trend to sell kits rather than contract testing services which is consistent
with the Company's marketing plan.

     The Company's product costs totaled $168,000 for the three month period
ended March 31, 1996 compared to $134,000 for the same period of 1995. Product
costs have increased 25% while production volume has increased 173%. Cost per
unit of output for the quarter ended March 31, 1996 decreased 54% compared to 
the first quarter 1995 largely as a result of increased volume as well as 
continued efficiency gains made in the production process during the first 
quarter of 1996 compared to the first quarter of 1995.

     The Company's research and development expenditures totaled $745,000 for 
the three month period ended March 31, 1996, compared to $834,000 for the 
three month period ended March 31, 1995.  The decrease is due primarily to a 
decline in expenses associated with the Company's clinical trials in the first
quarter of 1996 compared to the same period of 1995, while research and 
development activities associated with the Osteomark immunoassay and research 
and development expenses associated with the Company's monoclonal antibody
laboratory have remained constant.  The Company intends to expand its research
and development activities during the next several years.

     Selling, general and administrative expenses totaled $1,855,000 for the
three month period ended March 31, 1996, compared to $1,109,000 for the same
period ended March 31, 1995.  The higher expense level during the three months
ended March 31, 1996 was due to the implementation of marketing programs to
support the launch of Osteomark in the U.S., and the addition of sales 
personnel to support in these efforts.  The Company intends to continue its 
marketing efforts during the next several years.



     Interest income totaled $412,000 for the three month period ended 
March 31, 1996, compared to $318,000 for the three month period ended 
March 31, 1995.  The increase is the result of the cash available for 
investment from the initial public offering of Company common stock, completed 
on January 25, 1995, being invested for a longer period during the first 
quarter of 1996 than during the first quarter of 1995.


LIQUIDITY AND CAPITAL RESOURCES

     The Company has financed its operations from inception primarily through 
an initial public offering of 3,645,642 shares of common stock, which 
generated net proceeds of approximately $32,000,000, and three private 
placements of preferred stock aggregating approximately $12,800,000. Additional 
funds of approximately $9,200,000 have been generated through collaborative 
research and licensing agreements, sales of the Osteomark immunoassay kits and 
research testing services. As of March 31, 1996, the Company had $25,752,000 in 
cash and cash equivalents and short-term investments, working capital of 
$26,451,000 and total stockholders' equity of $29,641,000.

     During the three month period ended March 31, 1996 the Company used
$1,772,000 of cash for operating activities as compared to $1,785,000 during 
the three month period ended March 31, 1995.  The primary reason for the change 
was the increased net loss partially being offset by collections of significant
trade receivable balances during the three month period ended March 31, 1996. 
Total cash provided by investing activities was $210,000 for the three months 
ended March 31, 1996 compared to $13,261,000 used in the same period of 1995. 
The proceeds provided by investing activities in the three month period ended 
March 31, 1996 were primarily the result of more short-term investments 
maturing during the period than were purchased. During the same period ended 
March 31, 1995, most investing activities focused on using cash made available 
by the Company's initial public offering to purchase shortterm investments.  
The Company expects its cash requirements to increase in future periods.  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 enforcing and arbitrating distribution agreements and the time and costs 
involved in obtaining regulatory approvals.

     The Company intends to seek additional collaborative or license agreements
with suitable corporate partners.  There can be no assurance, however, that the
Company will be able to enter into such agreements or that the amounts received
under such agreements will materially reduce the Company's funding 
requirements.  Additional 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 
1998. 

     Forward looking statements in this Form 10-Q involve a number of risks and
uncertainties including, but not limited to, product demand, 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
arbital 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.  At the present time management cannot estimate the amount of
damages, if any, which may be awarded to either party.

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).  The accompanying unaudited
condensed 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 March 31, 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.  SHAREHOLDERS' EQUITY:

Initial Public Offering

On January 25, 1995, the Company successfully completed its
initial public offering of 3,645,642 shares of common stock
at $9.50 per share for proceeds of $34,634,000, less
underwriting discounts, commissions and other offering costs
of $3,085,000. In addition, at closing of the offering, the
outstanding convertible preferred stock was automatically
converted into 5,293,260 shares of common stock and 213,204
additional shares of common stock were issued to the Series
C preferred shareholder pursuant to certain anti-dilution
provisions.
