2011 Surgical Guidelines Recommend Point-of-Care Platelet Reactivity Testing Prior to Surgery

Management of Antiplatelet Drug Therapy Important to Quality Improvement

SAN DIEGO, March 9, 2011 - Accumetrics, Inc., a privately-held developer and marketer of the
VerifyNow(R) System, the first rapid and easy-to-use point-of-care system for
measuring platelet reactivity to multiple antiplatelet agents, announced
today that new Guidelines were recently published in The Annals of Thoracic
Surgery that include point-of-care testing for platelet reactivity as a new
recommendation for preoperative patient assessment(1).

Coronary artery bypass graft (CABG) patients on antiplatelet drugs have
an increased risk of excessive perioperative bleeding. Clopidogrel
(Plavix(R)) is often discontinued for 5-7 days before surgery to reduce this
bleeding risk. Due to the considerable variability in patient response to
clopidogrel, the Guidelines recommend point-of-care testing to "identify
clopidogrel non-responders, who are candidates for early operative coronary
revascularization and who may not require a preoperative waiting period after
clopidogrel discontinuation."

The VerifyNow P2Y12 Test allows clinicians to measure the actual level of
platelet reactivity in patients who have taken P2Y12 inhibitors (e.g. Plavix)
and who have discontinued them prior to surgery. By integrating this
information with other clinical data, clinicians are able to make more
informed decisions regarding a patient's treatment and surgery schedule in
their efforts to minimize bleeding risk and maximize patient safety.

"As the Guidelines recommend, it is very important to know which patients
are at risk of bleeding," stated Dr. Alex Zapolanski, Cardiac Surgery
Director at The Valley Heart & Vascular Institute in Ridgewood, NJ. "We use
the VerifyNow P2Y12 Test as a key piece of data to help us decide when a
patient can be taken to surgery. We have found by incorporating the test into
our practice that we have been able to reduce the average pre-surgical
patient length of stay by 3 days, resulting in significant cost savings."

"Accumetrics applauds the Society of Thoracic Surgeons and the Society of
Cardiovascular Anesthesiologists for the inclusion of point-of-care platelet
reactivity testing as a new recommendation in the Blood Conservation
Guidelines to improve outcomes and patient safety," said Timothy I. Still,
President and CEO of Accumetrics. "Cardiac surgery, interventional cardiology
and clinical cardiology are all segments in the continuum of cardiovascular
patient care where the VerifyNow System provides valuable data to healthcare
professionals."

The VerifyNow System is widely used in various clinical settings where
antiplatelet medications are prescribed to reduce the occurrence of future
thrombotic events such as heart attack and stroke.
