What Week Did You Find Out Your Baby Had Down Syndrome Through Ultrasound
Down's Screening: Full intergrated test consists of ultrasound measurement of nuchal translucency at 10 to 13 weeks combined with other test for serum markers has the detection rate of 85 to 95 percent and the lowest false positive rate for Down's syndrome screening tests ...Read moreSee 2 more doctor answers
An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more
Not precisely!: Ultrasound cannot diagnose a fetus with down syndrome (trisomy 21). It can pick up "soft" markers for downs. If you indeed identify soft markers, a discussion with your physician is critical to ascertain the risk of having an infant with a chromosomal abnormality. Further prenatal testing may be considered such as cvs or amniocentesis. It can be a difficult decision to make. ...Read more
Could high levels of hCG point to down syndrome? Mine were around 245, 000 at 9.2 weeks. Have had ultrasound and only one baby.
Range for normal HCG: Levels at 9-12 weeks lmp is 25, 700 – 288, 000 miu/ml, so yours is ok. At 11-14 weeks, a skilled ultrasonographer can determine if there is increased fluid under the skin at the base of the fetus' neck, a sign that other screens or diagnostic tests for ds are neeeded. A "quad" test that measures 4 pregnancy hormones screens for increased risk of certain birth defects including ds at 16-18 weeks. ...Read more
Can a 20 week Anatomy ultrasound pick up down syndrome in the baby ? I have an increased risk of a 1 in 89 chance of having my baby born with DS
Didn't you ask this?: Your risk assessment was obsolete, Ultrasound detection of Down at 20 weeks misses many. Demand a test of freei fetal DNA in your blood sample--your PCP can order the Harmony test from Ariosa: call 1-855-9-ARIOSA (855-927-4672) In over 15,000 pregnancies they detected 100% of Down syndrome and the chance of a false positive was less than 1 in 1000. Results in 4 to 8 days. ...Read more
My doctor didn't find any Down syndrome markers in the ultrasound. Does that guarantee my baby won't have down syndrome?
No. OB's combine the: results of an integrated screening test that includes specific blood tests in both the first & 2nd trimesters + the first trimester ultrasound to determine a single Down Syndrome risk rating. Only prenatal diagnostic tests of fetal genetic material for either Karyotype to determine # of chromosomes or Chromosomal Microarray to determine mutations in smaller gene sequences are definitive. ...Read more
T1;14(p22;q32: commonly seen in extranodalMZL associated with lymphomas downs syndrome translocation involves different chromosomes so the chance of downs syndrome is that of the general public not any more ...Read more
Has any one had the blood test positive for Down syndrome but then ultrasound showed the baby fine?
Accuracy matters: The ultrasound is a screening test, and as such may over or underestimate the presence of what is being looked for. Accuracy is often dependent on the training of the tech and or who reads the study.The blood test is a definitive test, it is either positive or not.I would never rely on the ultrasound for any decision other than pushing me to order the blood test . ...Read moreSee 1 more doctor answer
I had an emergency ultrasound because my quad screening was abnormal. mainly for down syndrome. is there a chance my baby will be ok?
Yes: Women with quad screen positives will have a chance to carry infant with Down syndrome at risk of 1 in 117. Integrated screening test that identifies 90 percent of Down syndrome pregnancies with only 2 percent false positive rate will identify a group of women to have Down syndrome pregnancy at risk of 1 in 16. ...Read more
I had a 12 ultrasound and no nasal bone was found that's it mean my baby has Down syndrome or it may be to little to tell help i'm worried please?
Needs followup: Although suspicious, it may be too early to tell for sure. Data are better for 2nd trimester ultrasounds, in the 15 to 20 week range. Please see your ob/gyn and discuss consultation with high risk OB and a plan for further testing and additional OB us. Based on epidemiology (population analysis - not necessarily true for you!): hypoplastic nasal bones - .5-1.2% normal fetuses vs. 43-62% down's. ...Read more
I had my 20wk ultrasound.They told me that she had a mild increase in nuchal fold.Quad screen was negative.Could my baby have down syndrome?Worried
See below: First off, it's very easy and common to make the nuchal fold look big when it really isn't, so that's the good news. Bad news is that if it truly is thickened, it is concerning. A nuchal fold over 6 mm increases the risk of down's by 17 times. So divide your quad screen results by that for true risk. Again, if truly large, would consider an amniocentesis. Could also get a level 2 us to confirm. ...Read more
Down syndrome is the classic presentation clinically of the congenital malformation syndrome also known as Trisomy 21. Classic features may include simian creases, epicanthal folds, upslanting palpebral fissures, flat nasal bridge, hypertelorism, low set ears, endocardial cushion defects of the heart, atlanto-axial joint instability, blood ...Read more
