What is nuchal translucency screening?

What is nuchal translucency screening?

Nuchal Translucency : Nuchal Translucency is a screening test to determine risk of chromosome abnormalities in a fetus. When the NT is greater than 3.5 mm, there is a 1 in 5 chance of a chromosome abnormality such as Turner or Down syndrome, or Trisomy 18. Additional tests should be ordered by an OB or genetic counselor for confirmation. A mother may decide to continue or end of the pregnancy based on the information. ...Read more

Screening (Definition)

Examples are: colonoscopy for colon polyp or cancer; mammograms for breast lesions or cancer; psa a blood test that could indicate enlargement of cancerous prostate tissue; blood sugar or hemoglobin a!c for diabetes. Many think that scanning the whole body will pick up a cancer--in all likelihood, it will not. There also is no good blood test, yet, ...Read more

Safety of chorionic sampling vs. Amniocentesis for prenatal diagnosis of chromosomal abnormalities?

Safety of chorionic sampling vs. Amniocentesis for prenatal diagnosis of chromosomal abnormalities?

Risks: The risk of pregnancy loss has been looked at in four randomized studies of cvs vs. Amniocentesis. All four studies show that both procedures have about the same risk of pregnancy loss. About 1 in 1600. Another cvs study showed that losses in a group of women who had the procedure were equal to losses in a group of women who didn't have the procedure. A loss may not be related to the procedure. ...Read more

What are amniocentesis, chorionic villus sampling and blood/saliva test screening used for? Abortions?

Prenatal diagnosis: Cvs and amniocentesis are used to discover chromosomal abnormalities in the fetus. They are also used to diagnose genetic diseases, such as cystic fibrosis, that some people are at risk for. Blood and saliva screening tests are used to find out if parents are at risk for a baby with certain genetic diseases. ...Read more

Ultrasound showed a gestational sac of 9 wks. Fetal pole not clearly visualized corresponding to 8wks 3 days, unable to detect fetal heart motion. ?

Ultrasound showed a gestational sac of 9 wks. Fetal pole not clearly visualized corresponding to 8wks 3 days, unable to detect fetal heart motion. ?

Repeat: The difficulty visualizing the fetal pole and heart beat at 9 weeks could be a result of the quality of the ultrasound. A repeat ultrasound and/or serial quantitative HCGs would help to clarify what is going on. Hope this helps. ...Read more

10 weeks transvaginal ultrasound baby heartbeat is 183 what about gender of baby?

20 weeks for gender: Domea: the gender of the baby is usually seen at the time of your full anatomy scan which is 18-20 weeks. Sometimes it can be seen sooner or sometimes the baby's position and other factors keep us from seeing it even when you are at the right gestational age. The heart rate is not a good predictor of the baby's gender. ...Read more

Does noninvasive prenatal testing(cfDNA )capture baby's genetic defects?Is amniocentesis better for more accurate results? Im 31&12 weeks pregnant.

Does noninvasive prenatal testing(cfDNA )capture baby's genetic defects?Is amniocentesis better for more accurate results? Im 31&12 weeks pregnant.

Some and yes: The cf-DNA can detect many genetic anomalies but it is not 100% and when positive is usually confirmed by an amniocentesis for a full karyotype. The amniocentesis is the gold standard for detecting genetic anomalies . Sampling of the placental tissue _ ie: chorionic villus sampling would be comparable to an amniocentesis and can be performed earlier in the pregnancy. ...Read more
