IRIS REALIGNS  MANAGEMENT  FUNCTIONS AT DIAGNOSTIC  UNIT FOLLOWING  DEPARTURE OF
UNIT PRESIDENT

EXPECTS CONTINUED GROWTH IN REVENUES AND PROFITS IN 2007

CHATSWORTH,  Calif.-- IRIS  INTERNATIONAL,  INC. (NASDAQ:  IRIS) today announced
that  Dino M.  Alfano,  Corporate  Vice  President  and  President  of the  Iris
Diagnostics Business Unit, is no longer employed with the company.

"In light of Mr. Alfano's decision to leave the company, we are accelerating the
planned  realignment  of  management  functions at the Iris  Diagnostics  Unit,"
stated IRIS President and Chief Executive Officer Cesar Garcia,  who will assume
direct  responsibilities  for  the  Diagnostics  Unit  until  a  replacement  is
identified.

"The  Diagnostics  Unit is deep in seasoned  management  and has recently  added
several industry  veterans with exceptional  credentials,  each of whom is quite
experienced and successful at those activities required to accelerate an already
strong  business,"  Mr.  Garcia  said.  "We  have  recently  added a new  senior
executive to oversee the underperforming service sector and will be adding a new
head of sales to take charge of the  commercialization  of new products  planned
for 2007 and to accelerate record revenue growth."

Mr. Garcia  continued,  "We  anticipate  record  contributions  in 2007 from the
Diagnostics  Unit,  spurred  not  only  by  continuing  robust  sales,  but by a
restoration  of  higher  margins  in  the  consumables  and  service  end of the
business.  IRIS will exit 2006 with record  revenues,  a significant new product
pipeline, no debt, cash of almost $20 million and high expectations for 2007."

"The Board of Directors fully supports the initiatives taken by Mr. Garcia,  who
has  displayed  extraordinary  leadership  and resolve,"  stated Board  Chairman
Richard H.  Williams.  "We remain  confident  that,  under his  leadership,  the
management  team will deliver  results and extend our business into new areas of
diagnostics, all internally funded."

Forward-looking  statements include, but are not limited to, the Company's views

product introductions and acquisitions,  and are generally identified by phrases
such as "thinks," "anticipates,"  "believes," "estimates," "expects," "intends,"
"plans," and similar  words.  Forward-looking  statements  are not guarantees of
future performance and are inherently subject to uncertainties and other factors
which could cause actual results to differ  materially from the  forward-looking
statement. These statements are based upon, among other things, assumptions made
by, and information currently available to, management,  including  management's
own  knowledge  and  assessment  of the  Company's  industry,  R&D  initiatives,
competition and capital requirements. Other factors and uncertainties that could
affect the Company's forward-looking statements include, among other things, the
following: identification of feasible new product initiatives, management of R&D
efforts and the  resulting  successful  development  of new products and product
platforms;  acceptance by customers of the Company's  products;  integration  of
acquired businesses;  substantial  expansion of international sales; reliance on
key suppliers;  the potential need for changes in long-term strategy in response
to future  developments;  future  advances  in  diagnostic  testing  methods and
procedures; potential





changes in government  regulations and healthcare policies,  both of which could
adversely affect the economics of the diagnostic testing procedures automated by
the Company's products;  rapid technological  change in the microelectronics and
software industries;  and competitive  factors,  including pricing pressures and
the introduction by others of new products with similar or better  functionality
than our  products.  These  and  other  risks are more  fully  described  in the
