We have included Primary Indication Tables to provide information that will allow ordering physicians, nurses and physicians’ assistants to compare patient symptoms and indications of exams to final results. The indication data tables include percentages of patients who present with a particular symptom or indication.

Also included are tables that include the percentages of those exams that were:

Positive for hemodynamically significant disease (>70% stenosis) in Carotid examinations
Positive regarding the presence of atherosclerotic disease in Lower and Upper Extremity Arterial examinations, or
Positive regarding the presence of acute deep vein thrombosis in Lower and Upper Extremity Venous examinations.

Another table we have included is Hours Until Final Report Signed by M.D. to provide information regarding the number of hours that it takes our preliminary reports to be read and the final reports signed by our medical directors.
