cut off below one has to 250 is supposed to be something suspicious for down syndrome but all the other values which you have specified seems to be normal. If you want to be very sure about the possibility of down syndrome you have to undergo amniocentesis if not you can try and non-invasive procedure called NIPT

If there is a positive risk for trisomy 21, further testing should be done in the form of non-invasive prenatal testing to confirm the diagnosis and accordingly the course of action should be planned.
