Tetra results: Low AFP - High DIA - Normal uE3 - Normal hCG - Down Syndrome?

I found out two Mondays ago that my AFP tetra test came back abnormal, and I was given a risk ratio of 1:105 for Down Syndrome. Next Thursday, I am being sent to the Medical University of South Carolina for a level II ultrasound and possible amniocentesis. I know that low AFP and high DIA values increase my chances of a Down Syndrome. That's isn't my question. My question is, are my MoM values still considered normal, just outside the median? I have .58 MoM for AFP (I understand multiples of the median) and 2.48 MoM for DIA. I just need more information, and 20+ hours of studying websites isn't helping. Please, any professional advice about my scores (or encouragement) is greatly appreciated.
