Should I have cvs or amniocentesis?

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 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

Why should I get cvs or amnio?

Why should I get cvs or amnio?

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 more

Neurofibromatosis: Yes. Prenatal testing with amniocentesis or chorionic villus sampling can detect Neurofibromatosis Type 1. NF-1 occurs as a gene mutation on chromosome 17. Half the cases are inherited as autosomal dominant and half of the cases can be spontaneous. ...Read more

Should I get amnio to have fetus tested for turner syndrome?

Should I get amnio to have fetus tested for turner syndrome?

Easier ways to tell: While ultrasound can give some hopeful results, you can get a definitive analysis by doing the NIPP.This test was developed early on to verify paternity, but it uses fetal cells that can be found in mother's blood as early as 8 weeks.These can be used for a full chromosome assessment including Turner syndrome. ...Read more

Do you think I should be working out 3 or 4 times a week if I have spina bifida and knee problems?

Do you think I should be working out 3 or 4 times a week if I have spina bifida and knee problems?

Yes, but....: Yes, you should be doing moderate exercise, but as much as your body can tolerate. Don't over do it, otherwise you could potentially cause harm to both of your conditions. Try not to put too much strain on your knees. A good exercise in such situations is swimming. Good luck! ...Read more

If I have an incompetent cervix i dilated at 14 weeks do I still have to have a d&e or can I have d&c?

If I have an incompetent cervix i dilated at 14 weeks do I still have to have a d&e or can I have d&c?

Technicality only: D&C and D&E are not that different; yes, technique and risks are slightly different, but it's kinda moot point. The specific difference is using a curette (D&C) and there is a limit to the size of products of conception (POC) that can be evacuated (think vacuum hose and bowling ball). The cervix can only be dilated so much mechanically. D&E uses instruments to fragment the POC thus has no limit. ...Read more

My quad results showed I have a 1:454 of having a child with Down's Syndrome. Should I have an amniocentesis performed? I am currently living in China and my doctor recommended I get the amniocentesis but I am not sure I should since the risk for DS is so

Amnio has risks too.: Only you can make a decision regarding your pregnancy, but how will the results of the test alter your decision to carry pregnancy to term? Will it affect you ability to bond with your unborn baby? Overall lifetime risk of DS is 1:800 but slightly less in women under 30 and significantly higher after age 40,, so your risk is still low. www.mayoclinic.org/tests-procedures/amniocentesis/basics/ ...Read more

Why do I have to have an amniocentesis and not a nuchal scan to check for down's?

Diagnosis/Screening: The nuchal fold measurement is a marker for down syndrome and is used in screening algorithms to assess risk for downs. However, it is not a diagnostic test. The diagnostic test to definitively tell if you are carrying a baby with down syndrome is the amnio or cvs depending on gestational age. These test collect fetal cells that can then have the chromosomes counted. ...Read more

If you have a breech baby, do you have them vaginally or c-section?

If you have a breech baby, do you have them vaginally or c-section?

Cesarean: Among breech babies, >50% switch to cephalic at 32wks, and it even happens at 38wks spontaneously. OBGYNs can perform a VERSION to flip baby at term, but DON'T TRY @ HOME. All breech babies should be delivered via C-Section b/c the risk of vaginal delivery is too great (head entrapment and fetal death due to cord compression). Only in RARE situations are vaginal deliveries performed. ...Read more

If I have an intrauterine infection, will I need a c-section?

If I have an intrauterine infection, will I need a c-section?

Not necessarily : There's more info needed but usually a term pregnancy with an intrauterine infection (chorioamnionitis) needs delivery, usually induction & not necessarily surgery. Earlier pregnancy may miscarry (septic abortion) and require antibiotics. If not pregnant, future pregnancies should not require c-section. I hope that helps. If you're currently pregnant, talk to your ob, they should be available 24/7. ...Read more

Do I have to have an abortion if amnio is bad?

Do I have to have an abortion if amnio is bad?

Depends.: This is a personal decision and there are only rare conditions when a pregnancy termination is warranted/recommended (lethal fetal anomalies). Many women/families are perfectly content to have a child with down syndrome (mongolism) and would never regret their decision to continue an affected pregnancy - whereas others would cringe on that prospect. ...Read more
