My maternity 21 test came back positive for down syndrome, but my ultrasound is normal. will my amnio tomorrow say the same, or different results?

Screen vs definitive: When you are trying to test for something in large populations (pregnant women) it is common to screen with a less invasive test and only do the more invasive (and costly) test if the screening suggests a problem.The amnio will get babies cells for study, and the results will be definite.A positive study means ds is present a negative, it is not..
