Hi I am 29 years old. I had positive result in QUAD screen test in 17 weeks pregnant. the result is 1:67 for down syndrome. I have not had any ultrasound scan till now. the quad screen test was based on the estimated delivery date. No one in mine or my husband's family including far far relatives also don't have any problems and even we both are healthy but recently i have hypothyroidism from last 2.5 years. After seeing the positive result I am totally devastated and don't know what to do. Doctor suggested me to consult perinatologist. Now i am very scared what they would say and about amniocentesis tests. Please advice me ur experience or any alternative blood tests to check further in houston, texas. Is there any chance that perinatologist tell me everything is fine just after they do the ultrasound or do I have to take amnio to be 100%. does anyone think perinatologist does the amnio just because it is coverd by my insurance. Any advice is appreciated.
