            CEPHEID REPORTS FOURTH QUARTER AND FULL YEAR 2006 RESULTS

SUNNYVALE, Calif., February 22, 2007 -- Cepheid (NASDAQ: CPHD) today announced
financial results for the fourth quarter and full year ended December 31, 2006.

Total product sales for the fourth quarter ended December 31, 2006 were $21.6
million. Sales results were mixed for the three markets in which the Company
participates. Clinical product sales for the fourth quarter increased by 81% to
$6.2 million. Industrial product sales increased by 5% to $3.8 million. The
increases in the Clinical and Industrial product sales were offset by a 24%
decrease in Biothreat product sales to $11.6 million. This resulted in an
overall decrease in total product sales of 3% from the $22.2 million for the
fourth quarter ended December 31, 2005. Total product sales for the full year of
2006 increased 2% to approximately $82.4 million from approximately $80.4
million for the full year of 2005.

Net loss for the quarter ended December 31, 2006 was approximately $8.3 million,
or $0.15 per share. The fourth quarter 2006 net loss included a one time expense
of $3.4 million for settlement of the Idaho patent dispute, which represented
$0.06 per share, and $2.1 million of stock compensation expense, representing
$0.04 per share. This is compared to a net loss of approximately $3.2 million,
or $0.08 per share, for the quarter ended December 31, 2005 when stock
compensation expense was not required to be included prior to the implementation
of SFAS 123(R). Net loss for the full year of 2006 was $26.0 million or $0.50
per share (including stock compensation expense) compared to a net loss of $13.6
million or $0.32 per share for the same period of last year (which did not
include stock compensation expense). The net loss for the full year of 2006
included the previously noted one time expense of a $3.4 million settlement of a
patent matter, or $0.06 per share, as well as $7.3 million of stock compensation
expense, or $0.14 per share.

Clinical product sales increased 81% to $6.2 million in the fourth quarter of
2006 from $3.4 million in the fourth quarter of 2005 and represented 29% of
total product sales for the fourth quarter of 2006 as compared to 15% of total
product sales for the fourth quarter of 2005. Clinical product sales increased
114% to $19.6 million for the full year of 2006 from $9.2 million for the full
year of 2005 and represented 24% of total product sales as compared to 11% of
total product sales for the full year of 2005.



Industrial product sales increased 5% to $3.8 million in the fourth quarter of
2006 from $3.6 million in the fourth quarter of 2005 and represented 17% of
total product sales in the fourth quarter of 2006 as compared to 16% of total
product sales in the fourth quarter of 2005 while Industrial product sales
increased 10% to $14.8 million for the full year of 2006 from $13.4 million for
the full year of 2005 and represented 18% of total product sales for the full
year of 2006 as compared to 17% for the full year of 2005.

Biothreat product sales decreased by 24% to $11.6 million in the fourth quarter
of 2006 from $15.2 million in the fourth quarter of 2005 and represented 54% of
total product sales in the fourth quarter of 2006 as compared to 69% in the
fourth quarter of 2005. Biothreat product sales decreased 17% to $48.0 million
for the full year of 2006 from $57.8 million for the full year of 2005 and
represented 58% of total product sales as compared to 72% of total product sales
for the full year of 2005. The expected decrease in product sales in the
Biothreat market was a result of the fourth quarter 2005 completion of the
installation of the Biohazard Detection System (BDS) units in the United States
Postal Service (USPS) processing centers and the resulting completion of
additional GeneXpert(R) modules sales for the USPS BDS program. In addition,
approximately $0.6 million of Anthrax cartridge sales were deferred pending the
outcome of current discussions of a potential five year test cartridge purchase
contract with Northrop Grumman and the USPS.

Other revenues, including contract and grant and government sponsored research
revenue, increased 41% to approximately $2.0 million for the fourth quarter of
2006 as compared to $1.4 million in the fourth quarter of 2005 while other
revenues increased 8% to approximately $5.0 million for the twelve months ended
December 31, 2006 as compared to $4.6 million for the twelve months ended
December 31, 2005. The increase in other revenues for the quarter and full year
as compared to the corresponding prior year periods was due primarily to the
initiation of development activities for the tuberculosis program with The
Foundation for Innovative New Diagnostics (FIND) and the Avian Flu program with
the Centers for Disease Control and Prevention (CDC).

The gross margin percentage on product sales for the quarter ended December 31,
2006 decreased to 42% from 43% compared to the prior year quarter. The cost of
product sales for the quarters ended December 31, 2006 and 2005 included $0.1
million and $0 of stock compensation expense, respectively, resulting in one
percentage point decrease on product gross margin in the fourth quarter of 2006.
The gross margin percentage on product sales decreased to 41% from 43% for the
full year of 2006 compared to the full year of 2005. The cost of product sales
for the full years of 2006 and 2005, included $0.6 million and $0 of stock
compensation expense, respectively, which had an impact of one percentage point
on product gross margin percentage for the full year of 2006. Aside from the
impact of stock compensation expense, the remaining decrease in gross margin for
2006 was primarily due to unfavorable product mix as compared to 2005.

"The Company continued to make good progress in expanding its Clinical product
line during the fourth quarter. The Xpert(TM) MRSA test was released as a CE IVD
marked product in Europe rounding out the Company's initial planned group of
GeneXpert system test products for the European market. To date the Company has
achieved an installed base of 136 GeneXpert systems in Europe and U.S. which
include 379 individual GeneXpert modules," commented John Bishop, Cepheid's CEO.



Mr. Bishop added, "510(k) clearance was also received during the fourth quarter
for the Smart(TM) GBS test on the SmartCycler(R) system. The Smart GBS test was
the Company's second product to be cleared through the FDA 510(k) process and
was completed in approximately 75 days."

"During the quarter, the Company also announced the receipt of Phase 1&2 funding
from the CDC for development of a CLIA waived test for influenza testing on the
GeneXpert system. The contract was one of four contracts awarded to companies
for development of tests and systems to be used for the pandemic preparedness
program."

"Driven by momentum in the third quarter, fourth quarter sales in the Industrial
market outpaced the fourth quarter of 2005."

"Biothreat sales are continuing at the expected rate. As previously noted,
installation of BDS units within USPS processing centers was completed during
the fourth quarter of 2005. As expected, no sales of additional GeneXpert
modules for the USPS program occurred in 2006. The program continues to run well
with over 4.3 million tests run to-date with no false positives. As previously
noted, the Company is currently in discussions with Northrop Grumman and the
USPS to potentially develop a five year anthrax test cartridge purchase
agreement. The potential five year agreement would initiate with the USPS 2007
fiscal year beginning October 1, 2006, resulting in the noted deferral of $0.6
million of sales revenue in the fourth quarter 2006."

2007 OUTLOOK

Commenting on Cepheid's outlook for 2007, Mr. Bishop stated:

"We expect 2007 to be a significant year of achievement for the Company.
Clinically, we expect to complete the initial U.S. offering of tests for use on
the GeneXpert system with the introduction of our Xpert MRSA test in mid year. A
510(k) for the Xpert MRSA product has recently been filed with the FDA. Based on
progress to date, we expect to launch our Enterovirus product, Xpert EV, in the
U.S. during the current quarter. Based on the strong interest we are seeing in
our GeneXpert systems and both the Xpert EV and Xpert MRSA products, we expect
our product sales to increase significantly in the second half of the year.
These new product launches will be supported with increased marketing and
promotional expenses as the rate of product adoption will have a determining
impact on our timeline to profitability and positive cash flow."

"Further momentum is expected to be gained in programs for the rapid expansion
of our clinical test pipeline. Our strategy is to augment our own internal
development programs with key collaborative programs which are expected to
significantly extend both our test menu and market reach. We are in the early
stages of several important collaborations which have the potential for global
impact on public safety and healthcare. Our programs for development of a rapid
tuberculosis test which simultaneously identifies drug resistance with FIND and
the National Institutes of Health (NIH) have the potential to bring molecular
diagnostics to the most remote regions of the world, where prompt and highly
accurate diagnostics are not available and are most needed. Likewise our
collaboration with the CDC may offer a solution to detect and help control the
unfortunate potential of an avian flu pandemic. And, subsequent to the end of
2006, we announced a collaboration with bioMerieux to develop tests for the
rapid detection and differentiation of organisms causing sepsis. As these and
other collaborations progress, we expect our contract revenues to double, or
possibly triple, last year's contract revenues, potentially reaching the $12 to
$15 million range. These programs will be supported with significant investments
in research and development."



"In the Biothreat market, we expect to either complete the five year contract
under mutually agreeable terms with Northrop Grumman and the USPS during the
second quarter or to return to use of a year-by-year contract and the
corresponding pricing matrix. The USPS anthrax test cartridge volume is expected
to be approximately the same as that for 2006, which was approximately 2
million."

"We expect sales in the Industrial market to be similar to those obtained in
2006."

"Further to the programs and initiatives already noted, subsequent to the close
of 2006 we completed the acquisition of Sangtec Molecular Diagnostics AB from
the Nycomed-owned ALTANA Pharma AG for approximately $27 million in cash.
Sangtec, based in Bromma, Sweden, develops and manufactures PCR based molecular
diagnostics products. Sangtec currently has 59 employees and had revenues in
2006 of approximately $8 million."

"The acquisition of Sangtec immediately brings Cepheid three key strategic
benefits. First, Sangtec currently has a relatively complete line of products
for potential use in managing infections of immunocompromised patients. Second,
Sangtec has a very strong R&D team experienced in developing real time PCR based
products which will enable Cepheid to more expeditiously expand its clinical
test product menu. Third, Sangtec has an accomplished manufacturing organization
noted for its ability to produce high quality products. This will provide
Cepheid with an established quality reagent manufacturing base in Europe."

"On a consolidated basis, we currently expect our 2007 total revenues to be in
the range of $112 million to $120 million, with product sales to be in the range
of $100 million to $105 million. We expect our 2007 net loss, not including the
effect of stock compensation expense which is currently estimated at $7 million
and any amortization expense arising from our recently announced acquisition, to
be in the range of $8 million to $11 million or $0.14 to $0.20 per share based
on expected weighted average shares outstanding of 55.6 million. We expect our
2007 net loss, when including the effect of stock compensation expense but not
any amortization expense arising from our recently announced acquisition, to be
in the range of $15 million to $18 million or $0.27 to $0.32 per share based on
expected weighted average shares outstanding of 55.6 million. We expect our
quarterly net income to show a definitive trend towards profitability in the
second half of 2007 based upon successful introduction of our Xpert EV and Xpert
MRSA IVD tests in the U.S. market. We expect to achieve positive operating cash
flow by the end of 2007 and to be profitable for the entire year of 2008."

"As of December 31, 2006, the Company had $94.9 million in unrestricted cash and
marketable securities."
