                             Developments
PORTLAND, Ore.--(Business Wire)--
Calypte Biomedical Corporation (OTCBB:CBMC), a developer,
manufacturer and marketer of HIV diagnostic tests, announced today
that its Chinese subsidiary, Beijing Marr Bio-Pharmaceutical Co. Ltd.
("Beijing Marr"), has received registration and marketing approval for
Calypte's Aware(TM) HIV-1/2 OMT (oral fluid) rapid test from the State
Food and Drug Administration ("SFDA") of China. This approval makes
the Aware(TM) HIV-1/2 OMT test the first and only SFDA approved rapid
oral fluid HIV test in China.

   Roger Gale, Calypte's Chairman and Chief Executive Officer,
stated, "This is a major accomplishment for Calypte and we are
thrilled to have received this long awaited approval which permits us
to begin actively marketing our rapid diagnostic tests in China, one
of the potentially largest HIV testing markets in the world. With the
medical devices manufacturing permit received earlier this year, our
Beijing Marr subsidiary is now able to manufacture, market, distribute
and sell the Aware(TM) HIV-1/2 OMT test throughout the Peoples'
Republic of China. China is committed to aggressively tackle the
spread of its HIV epidemic and we believe that our Aware(TM) HIV-1/2
OMT (oral fluid) test can and will make a significant contribution to
that effort. We appreciate the patience of those investors who have
supported us through the long SFDA approval process, particularly our
joint venture partners, the Marr Group." Mr. Gale added, "This
approval also gives us, for the first time, a very valuable approval
in the country of manufacture. Absence of this approval in the past
has hampered our ability to register and market the test in a number
of countries, a hurdle we can now overcome by producing the
domestically approved Aware(TM) product in our Chinese factory. With
this SFDA approval, we are now in a position to market and sell in
countries representing a total population of nearly 3.7 billion, or
over half of the worlds' population."

   Dr. Ronald Mink, Chief Science Officer for Calypte, remarked,
"This approval has validated our perseverance in pursuing the
registration of a product in which we have long had confidence. The
transformation of the SFDA over the past two to three years into a
first tier agency matching the rigor and integrity of its U.S. and
European counterparts resulted in a very thorough review of the
Aware(TM) HIV-1/2 OMT (oral fluid) test. We believe that the Chinese
authorities are now comfortable with this new technology, which
expands the scope of testing platforms currently available in China.
The SFDA's restructuring has resulted in a review process and
timetable that is similar to what we see in the U.S. FDA. We believe
these changes will benefit not only China, by setting a higher
standard for new medical products, but will also benefit us, by
setting a higher barrier to market entry for would-be competitors.
Throughout the entire review process, we received continually positive
feedback from the SFDA and we have been confident that our technology
is solid and our registration would prevail."

   David Harris, Beijing Marr's Chief Executive Officer, stated,
"This is a very exciting moment for those of us at Beijing Marr who
have worked very hard to gain this approval and ready the factory for
manufacture, sale and distribution of the Aware(TM) HIV-1/2 OMT test.
We have already received numerous inquiries from HIV program managers
and scientists eager to use the product here in China. We now plan to
ramp up our production capacity as we build our distribution network
to fully realize the market potential of the Aware(TM) HIV-1/2 OMT
test in China. Beijing Marr is committed to, and enthusiastic about,
bringing this exciting new technology to the Chinese medical
community."

   Calypte operates in China through Beijing Marr, a joint venture
between Calypte and the Marr Group established to manufacture
Calypte's Aware(TM) line of rapid HIV tests, including the Aware(TM)
HIV-1/2 OMT product for both the Chinese and international markets.
Beijing Marr operates an ISO 13485:2003 certified manufacturing
facility on the outskirts of Beijing. The Aware(TM) HIV-1/2 OMT
product is a rapid test using oral fluid to diagnose HIV-1 or HIV-2
infection in as little as 20 minutes with an accuracy comparable to
that of U.S. FDA approved blood based laboratory HIV EIA tests.
