Don't assume anything; call the doctor's office and tell them you need to hear the results. Medical offices are very busy these days, and things can fall through the cracks. Even if it's just that the doctor has a stack of reports from a lot of people to review, you want him to read yours and give you the results first.
Be a squeaky wheel, in a polite way.
And shame on that tech for raising your anxiety like this. She isn't qualified to report on the test, and shouldn't have told you something that may mean absolutely nothing.
