Additonal tests: There are additional, more definitive tests, e.g., amniocentesis, ultrasound examination, that should be done before you make a decision. The topic is not suitable for consultation in this forum. Please consult your doctor.

Odd report: There are screening tests (with such odds) and definitive tests (chromosome study) that are definitive. I would not make any big decisions based on a screening test.In some areas you can get a chromosome study as early as 8-9 wks on random fetal cells found in mothers blood. The most common definitive studies are done from an amniocentesis.
