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

What is non-invasive prenatal paternity testing?

What is non-invasive prenatal paternity testing?

NIPP: Non invasive paternity testing is a technology based on detection of fetal cells in the mother's blood. A variety of specialty labs offer this service and cite the ability to find such results as early as 8 weeks into the pregnancy. Traditional testing requires fetal cells from invasive procedures like sampling amniotic fluid by needle or the placental cells. ...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

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

Are there some prenatal tests for phenylketonuria (pku), or just the newborn screening test?

Are there some prenatal tests for phenylketonuria (pku), or just the newborn screening test?

Prenatal Dx of PKU: Phenylketonuria, pku is the result of the deficiency of the enzyme phenylalanine hydoxylase which converts phenylalanine to tyrosine. There is a prenatal test available to detect this enzyme deficiency. However there are rare forms of pku that result from cofactor deficiency or other enzymes that are involved in the conversion of phenylalanie to tyrosine. Pku is not a fatal genetic defect. ...Read more

What prenatal paternity test can be done in the last trimester?

Several: The presumed father can provide DNA through a blood sample or cheek swab. The only non-invasive, and thus, safest, way to get a sample from the baby before birth is from a blood sample of the mother. The baby's DNA is present in varying amounts beginning as early as the 8th week of pregnancy. Google The American Pregnancy Association for more info. ...Read more

Should everyone have  genetic testing before pregnancy?

Consultation first: Every couple can learn something from meeting with a clinical geneticist. They evaluate both family trees & can identify genetic issues you may be at risk for. With this information they can focus on which if any conditions to look for. There are in excess of 200 gene related defects they can identify, but there is no test that will identify all & many are studied only in a couple labs in the US. ...Read more

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

Is prenatal testing for thalassemia safe for baby?Is there any risk for baby ?My wife is 16 week pregnant and we both are diagonsed as minor carrier

Risks are small: With you and your wife being carriers, i suspect that the testing you are thinking about is amniocentesis. Amniocentesis is safe but not risk free. Many providers quote a miscarriage rate of around 1 in a 1, 000. But talk to your doctor about specifics in their practice and your concerns. The information from the testing may be valuable for your family. ...Read more

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 more

Why can't you wait until after babies are born to do prenatal testing if suspect chromosome or other problem?

Prenatal screening: You can wait until after birth, but the value of 'prenatal' testing - which means before birth - is it can be done early. Parents feel knowing about baby's medical problems before birth is good for coping and adjusting. Doctors who know in advance special care or surgery is needed can also anticipate and plan better for the baby's needs. But a mom may decline prenatal screening if she chooses. ...Read more
