Your doctor is probably right.
Tests are imperfect. In scenarios where the likelihood of the underlying disease in question is low, even a positive test result is likely to be a false positive. This, in turn, leads to more invasive/expensive/risky follow-up tests. It is not unusual for the risk of false positives to be greater than the benefits of finding occult disease.
Typically in these situations you read anecdotal claims about how this test saved my life. While occasionally such claims are true, you don't hear about all the thousands who underwent unnecessary invasive tests and procedures including complications for what turns out to be a false alarm.
The panel you described includes tests for aortic aneurysm, carotid stenosis, peripheral vascular disease -- guess what: those disease just happened to be testable by essentially the same instruments.
Trust your doctor in this case.
