Dear Barbara,
Yes the thallium can "miss" things as it is designed to look just for one
particular problem: decreased blood supply to areas of the heart AND it doesn't
even pick that up 100% of the time. In other words Barbara, your symptoms are
what you should pay attention to, not just the test results.
Diabetics often have atypical signs and symptoms of heart disease and this makes
it more difficult to diagnose. As well, "false-positive" thalliums are more likely
in women than men! And that is not the only test available to evalute you.
Definitely call you doctor and see him as soon as possible, and if that is
not a possibility, go to an emergency room or find a cardiologist who can
evaluate your significant cardiac risk factors and your recent problems.
I hope this information is useful. Information provided in the heart forum is for

Feel free to write back with further questions. Good luck!
