diaDexus Appoints Physicians Sales & Service to Distribute the PLAC(R) Test to
Physician's Office Labs

SOUTH SAN FRANCISCO, Calif., Aug. 27 /PRNewswire/ -- diaDexus, Inc. today
announced the appointment of Physicians Sales & Service, Inc. (PSS) as
distributors of the PLAC Test to physician office laboratories in the United
States.
The PLAC Test is the only blood test cleared by the United States Food &
Drug Administration (FDA) to assess risk for both coronary heart disease and
ischemic stroke associated with atherosclerosis. The PLAC Test provides new
information, over and above traditional cardiovascular risk factors, to help
identify individuals at increased risk of suffering a heart attack or stroke.
The PLAC Test measures lipoprotein-associated phospholipase A2 (Lp-PLA2), a
vascular-specific inflammatory enzyme implicated in the formation of
rupture-prone plaque. It is plaque rupture and thrombosis, not stenosis, that
cause the majority of cardiac events.
According to Patrick Plewman, president and chief executive officer of
diaDexus, the agreement is another important milestone for the company as it
continues to expand the availability of the PLAC Test beyond the traditional
laboratory setting. "This new relationship with PSS and its outstanding sales
force enables more people to benefit from assessment of their risk for heart
attack and stroke, events that can be prevented with appropriate lifestyle
modification and therapeutic treatment," Plewman said.
"PSS is excited to offer this important, high-value diagnostic test to the
physician lab customers we serve," said John Sasen, PSS World Medical's chief
marketing officer. "The addition of the PLAC Test to our offering demonstrates
our commitment to providing cutting edge technology to help clinicians deliver
high quality patient care in their office."
