high hcg levels and down syndrome?

I am 30 years old 17 weeks pregnant with my first child and received an abnormal reading on my quad screen. I was WNL for AFP, estriodal and inhibin-A. My HcG levels were at 3.98. 4 multiples above the median (which is 1.0). Given my age and normal markings for the other indicators, my risk is low. But how does the elevated level fo HcG relate to an increased chance of having a child with down syndrome?
