Trauma Equivalency Study of the CORA® and TEG® 5000 Systems

The purpose of the study is to validate the CORA System by comparing the results of this
test to that of the standard of care device called the TEG 5000 system. Both systems
evaluate hemostasis, a highly complex and interactive process involving many protein and
cellular elements, especially platelets, occurring in a series of interrelated phases, which
results in either normal hemostasis or a tendency toward bleeding or clotting complications.

The study protocol specifies testing using multiple reagents which are similar for both the
CORA and TG 5000 systems. Tests are run in duplicate on blood samples taken from patients
undergoing treatment for injuries and trauma. Following the protocol defined in CLSI
Standard EP09-A2, equivalence between the two systems will be demonstrated if the
conclusions from the Standard Section 7, Interpreting Results and Comparing to Internal
Performance Criteria, are found to be acceptable.

All blood samples drawn for this study will use venous blood. Only citrated or heparinized
whole blood samples are used. All samples are tested twice (run in duplicate). Quality
Control procedures are run on both instruments at a frequency specified by the
manufacturers. Results obtained from this testing are not used to make treatment decisions.

Inclusion Criteria:

- 18 years of age and older

- Complete patient history including age, race, gender and type of trauma should be
documented

Exclusion Criteria:

- Patients under the age of 18

- Native whole blood will not be used in this study
