Hi,
The risk of Trisomy 21 and Trisomy 18 increases when the ratio is less than 1 in 250. 1 in 50 indicates that the risk of Trisomy is high, but quad test is a screening test. To confirm I would suggest amniocentesis. Amniocentesis will tell us the baby's karyotyping thereby confirming whether baby is affected or not.
Hope I have answered your query. Let me know if I can assist you further.
