Exhibit 99.1

  ABAXIS AND HENRY SCHEIN, INC. AGREE TO DISCONTINUE DISTRIBUTION AGREEMENT

     ABAXIS EXPECTS MINIMAL FINANCIAL IMPACT ON THE QUARTER AND THE YEAR

    UNION CITY, Calif., May 22 /PRNewswire-FirstCall/ -- ABAXIS, Inc.
(Nasdaq: ABAX), a medical products company manufacturing point-of-care blood
analysis systems, announced today that Henry Schein, Inc. and Abaxis have agreed
to discontinue their veterinary products distribution agreement effective
immediately. Henry Schein distribution of Abaxis veterinary products accounted
for approximately 14% of Abaxis' total business in fiscal year 2006.

    Clint Severson, chairman and CEO of Abaxis commented, "This past March,
Henry Schein acquired a regional distributor of a competing company, creating a
level of uncertainty in the marketplace. In joint discussions it was determined
to be in the best interest of both Abaxis and Henry Schein to dissolve the
existing distribution agreement in order to clarify any misunderstanding that
might exist in the veterinary market. We are pleased to be able to move forward
with our plans to see to it that the Abaxis customer base continues to be served
at the highest level."

    Mr. Severson continued, "We believe that the loss of sales from the Schein
organization will be principally offset with increased sales in our other
domestic sectors, as well as increased international sales. We expect to meet
our internal quarterly and annual financial targets. We were involved in a
similar situation in December of 2004 and were successful in keeping Abaxis
users appropriately stocked with product in order to keep their veterinary
practices operating seamlessly. With a growing distribution network, both
domestically and internationally, that is driving increased market acceptance we
are better positioned to manage this type of situation and to maintain our
quarterly and annual financial goals."

    Martin Mulroy, Vice President Sales and Marketing for the Veterinary
Business, added, "With the recent successful introduction of our new VetScanVS2
analyzer we continue to have the leading-edge product for any veterinary
practice. Our existing distribution network is prepared to step right in and
service veterinary practices in order to ensure an orderly transition. We are
confident in our ability to keep potentially affected end- users stocked and
operating at their normal levels. Looking ahead, we remain steadfast in our
belief that we can continue to gain market share in the veterinary point-of-care
blood analysis market. We thank Henry Schein for all of their past efforts."

    On the veterinary side of the business, Abaxis now has 16 distributor
agreements in place in North America, four of which have been added this past
year. More than 40% of Abaxis' new business (instrument placements) is now sold
direct from the Company, while local distribution typically supplies the
consumable component of the Abaxis product line to the end user.
