Amnio test

Besides great snacks and daily foot massages, the next best thing for a woman and her unborn child is education. Knowing your body, how to protect it, and also how to engage in precautionary actions can help to keep your pregnancy safe. It can also help to calm some of the worries you may have by providing factual information. Like all mothers, you want your baby to be protected. Taking care of yourself physically and mentally will help with that, however there are other options as well. Two of the most common of tests that can be done are Chorionic Villus Sampling (CVS) and also Amniocentesis (Amnio).

Each of these test can be used to identify chromosomal abnormities, like Down syndrome, and other inherited disorders. According to the American Pregnancy Association, each test can provide results with accuracy ranging between 98 and 99%. There are times where there is a 1 % chance of a false positive reporting, but those chances are very slim. These tests can provide useful information to help expecting parents make planning options. Whether there is planning for a special needs child, preparing for a lifestyle change, or even the tough decision of carrying a child to term, these test can give real answers. And with these answers, you, your partner, and your healthcare physician can help determine what is best for your pregnancy.

Although these test may or may not be recommended by your doctor, you and your partner have the option to request to have it performed. If you should take this initiative, keep in mind that Baby Center tells us that CVS testing can be done between the 10th and 12th week of pregnancy. If you miss out on this period, there are some physicians that will perform this up to the 13th week and 6th day. As for the Amnio test, that can occur anywhere between the 14th and the 20th week. There are some cases where the procedure could be performed at the 11th week, at the very earliest. So if you are considering these tests, it may be a great idea to mark this in your calendar ahead of time.

If choosing to go with the CVS testing, there are two different methods that can be used to complete the procedure. The American Pregnancy Association says that it can either be performed using an ultrasound and a catheter which will enter through the cervix, or using a needle and drawling a sample of tissue from the abdomen. Using the needle method through the abdomen is also similar to that of the Amnio test. Both methods are safe, but it is recommended to opt out of the cervical procedure if you have any uterine fibroids or a tilted uterus. And along with any test there are, of course, risk factors involved. The largest risk for either test is the risk of miscarriage, simply because the test is so invasive. This is no reason to get scared. The odds are about 1 out of 200 for Amnio and 1 out of 100 for CVS. But before you do anything, talk to your doctor. They should be able to answer any additional questions that you may have.

One Response so far.
