Blondie,
Aside from family history of anything major, diabetes, heart problems, etc. I was given a blood test also, this is mainly to rule out an overactive or underactive thyroid, which mimics panic disorder. Some time later, can't remember when, he also did a 24 hour urinary output collection. When all the above came back negative, the diagnosis was complete with panic disorder, after my repeated attacks, etc.
