Amniocentesis For This Pregnancy Prenatal Testing
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 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
CVS or amniocentesis: Trisomies can be detected with chorionic villi sampling (cvs) or amniocentesis. Cvs is performed between 10-13 weeks, and involves removing a small sample of the placenta usually using a small tube, or catheter that is inserted through the cervix. Amniocentesis is performed between 15-20 weeks gestation and is a procedure where amniotic fluid is removed from around the fetus using a needle. ...Read moreSee 1 more doctor answer
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
Fetal DNA: Testing for free fetal DNA is available for detection of trisomies either from 9 weeks 0 days or 10 weeks 0 days, the latter being much less expensive. The results are available in 7 to10days with 99.99% accuracy. Both ACMG and FACOG recommend confirmation of an abnormal result with either amniocentesis or CVS. other non-invasive tests include fetal ultrasonography and prenatal screening. ...Read moreSee 1 more doctor answer
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
Minority of cases: Performing tests may find potential problems which might benefit from interventions or early delivery. Pregnancies requiring or benefitting from cesarian delivery i.e. Placenta previa or breech presntations. Can begin planning for chidren with special needs & identify support groups and resources. Some parents to be can not face the future with child with major deformities requiring fulltime care. ...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
Prenatal screening is the group of procedures used in pregnancy to look for diseases and genetic mutations in the fetus (baby inside Mom). Screening is usually done as early as practical in the pregnancy. Methods include testing the pregnant woman's blood, scanning the fetus with ultrasound, sampling the amniotic fluid ...Read more
If you're pregnant or planning to get pregnant, there are many things you can do to give your baby a healthy start: Regular prenatal visits along with laboratory testing, ultrasounds, prenatal vitamins and immunizations (like the flu shot and whopping cough booster).
