ve had three over the last 6 years, and one a few years before that when the test
was called a thallium stress test
...it is nuclear
too, but it seems thallium is no longer used.
I have no known side-effects and I have gotten two false positives. The latest one that gave this was about 2 years ago, and so I underwent a catheter study and there were no blocks.
I think the bottom line is, if the nuclear stress test says you do not have blockage, you most likely don't.
