Should I Have Cvs Or Amniocentesis
Maybe: CVS and amniocentesis are tests that some patients will choose to have to help get a diagnosis. They allow testing of the baby's genes and help diagnosis genetic defects. These tests are not done routinely on everyone but rather on those who are at high risk for genetic diseases. Age > 35 or an abnormal blood test for Down syndrome would be examples of those who might consider this. ...Read moreSee 1 more doctor answer
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
Personal decision: Both tests are 100% accurate in determining whether or not the baby has chromosomal problems like down's syndrome. Women over 40 have a 1 in 20 risk of this. Some people would terminate the pregnancy if they knew the baby had a chromosomal problem. The cvs gives you info earlier than the amnio but has a higher miscarriage rate. ...Read moreSee 1 more doctor answer
Personal decision: Your decision should be based on your age-related risk for chromosomal problems (higher the older you are), how important it is to you to get early information, and how much risk you are willing to take in finding out the information. Generally cvs will give you information one month before an amnio but has a risk of miscarriage triple that of an amnio. ...Read moreSee 1 more doctor answer
Colonized with gbs. Do I need antibiotics before, during and after cvs? Should I choose amniocentesis instead?
Invasive prenatal: Choosing to undergo invasive prenatal testing is an important decision and one best had with a perinatologist. The timing, whether to do early testing with CVS, later testing with amniocentesis or even nowadays we like to use noninvasive testing with free fetal DNA which poses no risk to fetus, will ultimately depend on what you are trying to test for. ...Read more
Follow instructions: No matter what you do, there is always a risk of miscarriage following these procedures. Most doctors who perform them will tell you to limit your activity for 24-48 hours after the procedure. Make sure to follow all instructions you are given to minimize the risk of miscarriage. ...Read moreSee 1 more doctor answer
Placenta vs fluid: Cvs can usually be done earlier and involves obtaining placental tissue for chromosome analysis. This is done by needle biopsy either through the cervix or abdomen. Amniocentesis is obtaining amniotic fluid for testing also by needle aspiration. Both are done with ultrasound guidance, cvs slightly riskier with bleeding & cramping, both safe to do, both done by mfm docs. I hope that helps. ...Read moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
CVS is Rare: Cyclical vomiting syndrome (cvs) is a diagnosis of exclusion. It is a rare problem. It has a very typical pattern of severe vomiting which lasts for less than 48 hours. In between episodes, people are totally fine. Attacks occur every few weeks or months. Acid reflux, gastroparesis, gallbladder and pancreas disease need to be excluded. Avoid marijuana - it has recently been implicated as a cause. ...Read moreSee 1 more doctor answer
Prenatal diagnosis: During a cvs, a thin needle/catheter is inserted into your placenta. Cells from the placenta are removed and sent to the laboratory. In this way we can check the chromosomes of your developing fetus. Depending on the placenta position and your provider preference this can either be done through the skin of your belly or through your cervix. ...Read moreSee 1 more doctor answer
Mild cramping: The physician will do an ultrasound to evaluate the fetus. A speculum will be placed and the cervix will be cleaned. A thin catheter is passed into the uterus and the placenta is sampled under direct ultrasound guidance. You may feel some cramping when this is done. There may be a small amount of bleeding after the procedure. ...Read moreSee 1 more doctor answer
Genetic info: These tests are for women who have a higher risk for having a baby with a genetic problem like down's syndrome and for women who would act on this information such as terminating the pregnancy. Though a cvs can obtain this information much earlier than an amnio, it has a much higher rate of miscarriage than an amnio. ...Read moreSee 2 more doctor answers
Many MFM, geneticist: Many specialists in prenatal diagnosis, including maternal-fetal medicine doctors and geneticists perform chorionic villus sampling transabdominally. The role for this invasive procedure is decreasing, though, as non-invasive fetal dna testing rapidly becomes widely accepted as the new standard of care for detection of severe fetal dna problems (e.g. Maternit21). ...Read moreSee 1 more doctor answer
