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

Amniocentesis (Definition)

Amniocentesis is a procedure used to draw a sample of the amniotic fluid that surrounds and cushions the baby in the womb. This fluid contains cells that have been sloughed off of the developing fetus. Amniocentesis is most often used to detect genetic abnormalities, though the results can also reveal the baby's sex, gauge lung maturity (if done close to term), detect amniotic fluid infections, or ...Read more

How often do I need to go in for prenatal testing?

Depends on risk: Prenatal care involves regular OB visits, but prenatal testing ranges from general screening (level i ultrasound, triple/quad/integrated screen, amniocentesis chromosomes) to gene tests when a prior child was affected--usually at 10-18 weeks . Realize that triple/quad/integrated screen looking for down syndrome markers is inaccurate, sometimes leading to amnio and termination. Caveat emptor. ...Read more

What are you looking for in prenatal testing for huntington's disease?

What are you looking for in prenatal testing for huntington's disease?

Prevention: If a parent is known to carry the huntington's mutation, there is a 50% chance they will pass this to their offspring. If undergoing ivf, the embryos can be testing for the gene, so that only unaffected embryos will be implanted. If already pregnant, chorionic villus sampling or amniocentesis can test for the gene, and affected pregnancies have the option of termination. ...Read more

My pastor told me to avoid prenatal testing since I would just worry and not act on the information. Should i?

Your decision: Whether to do prenatal testing or not is your decision, and not your pastor's. It can certainly cause some worry, but so can not knowing whether something is wrong with a baby. And whether to act on the information is also a very personal decision. Even very religious people sometimes choose to terminate a pregnancy if they know that a baby is going to die or have a very limited life. ...Read more
