Cepheid Announces New Diagnostic Technology to Aid World Efforts in Halting
the Spread of Mycobacterium Tuberculosis (TB)

SUNNYVALE, Calif.March 24 /PRNewswire-FirstCall/ -- Cepheid (Nasdaq: CPHD)
today announced details of technology expected to revolutionize the speed of
diagnosis of Mycobacterium tuberculosis (TB) and the resistance to common drug
treatment for the disease.

The new test technology, developed in partnership with Foundation for
Innovative New Diagnostics (FIND) and the University of Medicine and Dentistry
of New Jersey (UMDNJ), and funded by the National Institute of Allergy &
Infectious Diseases (NIAID), will leverage the power of Cepheid's GeneXpert(R)
System to deliver a highly accurate diagnosis of the disease in less than two
hours.

According to the World Health Organization (WHO), approximately two billion
people are infected with Mycobacterium tuberculosis. Each year approximately
nine million people develop active TB and two million people lose their lives
to the illness. This equates to one life every 20 seconds.

"One of FIND's main goals is to help to save the millions of lives that are
needlessly lost to TB every year," says Giorgio Roscigno, Chief Executive
Officer of FIND. "Cepheid's commitment to researching and bringing this test
to market has been outstanding, as is their intention to sell Xpert(R) MTB/RIF
on a cost for product basis in the developing world, where it is most needed.
We are proud to be working with them on this project."

Rapid diagnosis of TB is vital in areas such as sub-Saharan Africa and
Southeast Asia due to the close connection between HIV and TB. Sputum
microscopy, which often delivers poor sensitivity in patients suffering from
tuberculosis, is almost completely ineffective in those who also have HIV
co-infection. The weakened immune system of an HIV-positive person is
particularly susceptible to infection, resulting in one third of the 33
million HIV sufferers worldwide infected with TB. Left untreated, 90 percent
of these people will die within months of first contracting the disease,
reinforcing the urgent need for an accurate and rapid test.

"The need for accurate and rapid detection of tuberculosis is becoming
increasingly acute with the development of drug resistant strains and the
growing at-risk populations in the developing world," said John Bishop,
Cepheid's Chief Executive Officer. "The GeneXpert System has a unique level of
technical capability never before seen in molecular diagnostics and this
capability is on full display with the Xpert MTB/RIF test. Clinicians will now
be able to obtain dependable test results for not only detection of TB but
simultaneous determination of whether or not it is a drug resistant strain in
virtually any clinical setting. Appropriate therapeutic management has been a
significant factor in the development of drug resistant strains of
tuberculosis and the availability of the Xpert MTB/RIF test should be a
breakthrough technological leap forward in helping to ensure proper
therapeutic management and in helping to halt transmission. We are expecting
to make this test available as a CE IVD Mark product next month."

Xpert MTB/RIF not only detects the presence of TB, but also identifies whether
it is resistant to Rifampicin, a common first-line drug for treatment of the
disease and a reliable surrogate marker of strains that are
multidrug-resistant (MDR-TB). The test is expected to enable physicians to
dramatically improve patient outcomes -- possible only with on-demand,
actionable results to guide therapy decisions within the timeframe of an
initial patient visit.

"Multidrug-resistant TB is becoming increasingly prevalent throughout the
world, making TB harder to treat with the usual treatment regimen that
includes Rifampicin," said David H. Persing, M.D., Ph.D., Cepheid's Chief
Medical and Technology Officer. "In my opinion, this new test is one of the
most important diagnostic developments to have occurred in many years. It is
the most technologically advanced test for TB ever developed, yet it is simple
enough to perform in all corners of the world, including resource-limited
settings where it is most needed."

Currently, the most common testing method for TB is the sputum microscopy, or
smear test, that has remained largely unchanged in its sophistication and
sensitivity for over 100 years. The smear test has been proven to only detect
around half of all active TB cases and is not capable of identifying drug
resistance. Patients who remain undetected are often co-mingled within general
hospital populations, placing others at risk of infection. Due to their low
accuracy, smear tests are followed up with culture tests, which offer more
accurate results but take several weeks. To determine drug resistance, culture
testing can take months to return a result. For patients in the developing
world, lengthy turnaround times of current test methods can lead to
catastrophic consequences as the chain of transmission grows.

"We designed this test so that it could be used by someone with minimal
training," said UMDNJ's David Alland, M.D. who collaborated closely with
Cepheid and FIND with support from the NIAID. "We're gratified to find that
it requires less hands-on work than the acid fast smear, long a standard
method to identify tuberculosis, but it is much more sensitive."

About Cepheid
Cepheid (Nasdaq: CPHD), based in Sunnyvale, Calif., is a molecular diagnostics
company that develops, manufactures, and markets fully-integrated systems for
genetic analysis in the clinical, industrial and biothreat markets. The
company's systems enable rapid, sophisticated genetic testing for organisms
and genetic-based diseases by automating otherwise complex manual laboratory
procedures. The company's easy-to-use systems integrate a number of
complicated and time-intensive steps, including sample preparation, DNA
amplification and detection, which enable the analysis of complex biological
samples in its proprietary test cartridges. Through its strong molecular
biology capabilities, the company is focusing on those applications where
rapid molecular testing is particularly important, such as identifying
infectious disease and cancer in the clinical market; food, agricultural, and
environmental testing in the industrial market; and identifying bio-terrorism
agents in the biothreat market. See www.cepheid.com for more information.

About FIND
FIND, based in Geneva, Switzerland, is a not-for-profit Swiss foundation
dedicated to the development of improved diagnostics for poverty-related
diseases. FIND is dedicated to the development of tests that will have a
measurable impact on TB morbidity and mortality, particularly in high-endemic
countries. Since its establishment in 2003, FIND has received endorsement from
WHO for three new TB technologies that are currently being rolled out with
partners in 16 countries that carry a high burden of MDR TB cases. FIND's
mission is to drive the development and implementation of accurate and
affordable diagnostic tests that can be used as near as possible to where
patients first seek care. At this time, the FIND's disease portfolio includes
TB, malaria and human African trypanosomiasis and current donors are the Bill
& Melinda Gates Foundation, the European Union, the Government of the
Netherlands, UNITAID, Irish Aid and other institutions and private donors.
