EXHIBIT 99.1 CONTACTS: CESAR GARCIA PRESIDENT AND CHIEF EXECUTIVE OFFICER 818-709-1244 X123 OR RON STABINER, THE WALL STREET GROUP, INC. 212-888-4848 FOR IMMEDIATE RELEASE: IRIS POSTS RECORD PERFORMANCE AS 1ST QUARTER 2005 OPERATING INCOME DOUBLES ON 49% REVENUE GROWTH INCREASES 2005 GUIDANCE TO $0.30-$0.35 AND REVENUE GROWTH OF AT LEAST 35% CHATSWORTH, CALIF., APRIL 28, 2005 - IRIS INTERNATIONAL, INC. (NASDAQ: IRIS) today announced record revenues of $14.0 million for the first quarter ended March 31, 2005, and earnings of $0.08 per basic share ($0.07 per fully diluted share). The record performance results primarily from sales for its new iQ(R)200 Automated Urinalysis Analyzer and increasing recurring revenues from sales of consumables.

"We are very satisfied with the high demand for iQ200 analyzers in the first quarter," stated Cesar Garcia, Chief Executive Officer of IRIS. "Our international instrument shipments significantly exceeded our expectations while domestic instrument shipments were slightly ahead of expectation. After a very strong fourth quarter, I am pleased to report that we have achieved record quarterly revenues of $14.0 million and operating income of $2.0 million in a quarter that has been traditionally slow due to lower instruments sales. "This is our fifth consecutive quarter with sequential revenue growth, representing a 49% increase over the corresponding period last year. Our performance is beginning to reflect the anticipated increases in consumables and service, with quarterly revenues in this category exceeding prior year results by more than $1 million, an increase of 22%. We expect this trend to continue to accelerate as more instruments are put into routine use and more domestic customers acquire service contracts, after the expiration of the instrument warranty. "I am also pleased to report that our customers will be presenting 12 peer-reviewed scientific posters attesting to the superior clinical utility of our platform at the EUROMEDLAB Conference & Exhibit in Glasgow, Scotland, in May 2005. This international conference attracts more than 2,500 participants, typically laboratory scientists and technologists from around the world. We have also been informed that five additional peer-reviewed scientific posters submitted by our customers have been accepted for presentation at the American Association of Clinical Chemistry Conference in Orlando, Florida, in July 2005. The high level of interest demonstrated by the medical community confirms that the iQ200 Microscopy Analyzer has been adopted as the standard of care in urine microscopy." Mr. Garcia stated that "IRIS' new product pipeline became more robust with the recent U.S. Food and Drug Administration (FDA) 510k clearance of the iQ200 body fluids application and the market launch of the Express 3 centrifuge by our StatSpin small medical devices division. Both products will be commercially available during the second quarter. We also continue to make progress in our feasibility program to extend the iQ200 platform into advanced urinalysis applications that could open new market opportunities in the diagnosis of bacteria and rare cell detection in urine -- an estimated addressable market of approximately $300 million." IRIS International yesterday announced the signing of a definitive agreement to acquire the assets of the urine chemistry strip product line from Quidel Corporation. "We are addressing a significant international market gap with the acquisition of this product line and related intellectual property," Mr. Garcia said. "We believe that this strategic acquisition brings core technology that will allow us to compete more effectively and begin to participate in an estimated addressable international market consisting of 8,000 potential sites and representing $250 million in annual sales. Our revised financial guidance for 2005 incorporates the commencement of this business activity." The Company's operating income margin increased to 15% compared with 10% in the prior year quarter. "We must keep our eyes on our operating margin because average gross margins fluctuate from quarter to quarter depending on the mix between products sold directly and through distributors, and gross margin may not be the final indicator of the profit generation capability of the Company," Mr. Garcia said. He added that "the Company expects to achieve operating margins of at least 20 percent in 2006 and beyond." IRIS has now secured distribution in 50 countries, all through distributors, except in France where the company sells directly to end-users through its IRIS Diagnostics France SARL, based in Paris, France. (MORE) 2 Net revenues for the first quarter ended Mar. 31, 2005, rose 49% to $14.0 million, compared with $9.4 million in the corresponding quarter of 2004. Net income amounted to $1.3 million, or $0.08 per basic share ($0.07 per diluted share), on 16.2 million basic shares outstanding (17.3 million diluted shares), compared with net income of $529,000, or $0.04 per basic and diluted share, on 12.1 million basic and 13.8 million diluted shares outstanding during the first quarter of 2004. The IN VITRO diagnostics segment revenues grew approximately 57% during the first quarter. The international sector of this segment continues to get stronger, and represented approximately 31% of the IN VITRO diagnostics segment's first quarter revenues. "We are also pleased to report that revenue from consumables, supplies and services is growing and represented 49% of the first quarter segment revenues and approximately 41% of our consolidated revenues over the same period," Mr. Garcia stated. "Instrument bookings for the first quarter 2005 are stronger than anticipated, and our consumable revenue growth should continue to accelerate during 2005." Revenues from StatSpin, the Company's small laboratory devices subsidiary, were $2.3 million for the first quarter, up from $2.0 million in the year-ago quarter, an 18% increase. IRIS' gross profit margin was 49% in the first quarter versus 50% in the prior year quarter, primarily due to stronger sales of instruments versus consumables and service and increased international sales of iQ200 Microscopy Analyzers and related consumables through distributors at lower margins. As of Mar. 31, 2005, IRIS had $13.4 million in cash on hand and net operating loss tax carry-forwards of $16 million available for use in future years. REVISED 2005 GUIDANCE: o PROJECTED REVENUE GROWTH INCREASED TO AT LEAST 35% FROM AT LEAST 25% o PROJECTED EARNINGS PER SHARE OF $0.30 - $0.35 "Because of these results, we are increasing our guidance to reflect the strong demand that we are experiencing for the iQ200 Analyzer and the recently released iQ200 Sprint Analyzers," Mr. Garcia said. "During 2005, we expect consolidated revenues to grow at least 35% over 2004 and earnings to grow to $0.30 - $0.35 per share, on estimated diluted shares of approximately 18.3 million. Free cash flow will begin to grow at a significant rate in the second half of the year and we expect further escalation in 2006."
