How To Prevent Down Syndrome During Pregnancy
Chromosome analysis : obtained by amniocentesis or Chorionic Villous Sampling is diagnostic for Trisomy 21, other trisomies & monosomies. It is offered if the calculated statistical risk of DS from screening by blood tests & fetal ultrasounds + maternal age at EDD & family history reaches a cut-off point, often 1:270. This calculated risk method has an 80% detection rate & a 5% false-positive rate. ...Read moreSee 2 more doctor answers

(If 36, risk us 1:294; if 37, 1:227). Diagnostic tests are offered if calculated risk is high. ...Read more

Depends: Your risk of a second ds birth is about 1% plus any age factor risk if the first baby was a 21 trisomy.The most specific tests would be chorionic villus sampling or amniocentesis for chromosomal analysis. Cvs can be done in early pregnancy and amniocentesis around 16 wks.Both procedures have some risk to mom and the baby.There are some less invasive but less definitive tests.Ask ur doc. ...Read more
Hi doctor , in ultra suond.U/s congenital anomaly detect or down syndrome detect during pregnancy ?
Quad Marker Screen: The Quad Marker Screen is done between 15 and 20 weeks of pregnancy in select patients. It looks at levels of AFP, hCG, UE, and Inhibin-A. Low levels of AFP and UE and higher than normal levels of hCG and Inhibin-A COULD indicate that the woman is at higher risk for having a baby with Down's syndrome. It is not even close to 100% accurate (70%-80% at best). ...Read more

OB's offer 3 screens: 1st trimester combined test or 1st & 2nd trimester integrated test measure fetal nuchal, or neck, fold on FUS + levels of specific proteins & hormones in your blood. If risk of DS calculated from screen + your age at delivery, 1:350 if 35, 1:270 if 36, is high, choose an FUS for anatomical markers of DS + a cell-free fetal DNA blood test at > 10 wks. gestation or a more invasive diagnostic test. ...Read more
Discuss w/ Dr.: How high? What specifics? Discuss these concerns w/ your OBGYN. I've heard that the increased risk is specifically about a small portion of the hCG called the beta subunit. If that is high, they consider it an increased risk for Down Syndrome. It's not so much a concern early in pregnancy - they usually test for this between 15-18 weeks and it's part of the quad-screening test. I hope this helps. ...Read more
What are the typical prenatal tests to check for down syndrome? What week of pregnancy do they typically test for this?

My HCG at 5w5d (evening) was 22,000. I am concerned that this indicates down syndrome. Are high HCG levels in early pregnancy an indicator of DS?

Im 28 with an IVF pregnancy. My blood work came back with a high chance of down syndrome. Someone said it might be from the ivf?
Not from ivf: Down syndrome is a chromosome defect (trisomy or translocation). It is usually sporatic without cause. It can be familial or related to maternal age. The ivf process does not cause this defect, but the ovum and sperm used may already have the defect. Direct evaluation of fetal cell dna will be necessary to confirm the diagnosis. ...Read moreSee 1 more doctor answer
