Prenatal screening tests in Atlanta can be done by both CVS and Amniocentesis techniques. The main difference between these tests is their timings. The doctor suggests a CVS test in the first trimester period of the pregnancy whereas the Amniocentesis test occurs in the second trimester. Both tests have different advantages and disadvantages. Below you will read detailed information on both techniques and you can choose according to your convenience and safety.
CVS is an invasive prenatal screening test and is performed between the 10th and 12th weeks of the pregnancy period. This process involves taking a small tissue from the placenta and is very helpful in knowing the chromosomal abnormalities such as Down syndrome and genetic disorders i.e. cystic fibrosis. This CVS test is of 2 types; transabdominal and transcervical.
Cramps and spotting are the main two side effects of CVS tests. There is also a very small risk of miscarriage. It is an optional test. You don’t need to do it if you don’t want to.
The amniocentesis process includes the removal of amniotic fluid from the uterus for a testing procedure. This fluid borders the baby during pregnancy and contains fetal cells of the same genetic composition as a baby. Doctors suggest this prenatal screening test for various conditions such as:
- If you are 35 years old or more
- You or your partner are carrying any genetic abnormality
- If you had a chromosomal disorder in your previous pregnancy

What is one advantage of chorionic villus sampling over amniocentesis?
While amniocentesis is carried out around 15-20 weeks of pregnancy, the main benefit of chorionic villus sampling (CVS) is that it may be conducted between 10 and 13 weeks of pregnancy. If a chromosomal anomaly is found, this allows parents additional time to make options.
Why is amniocentesis a more widely used test than CVS?
Amniocentesis is utilized more frequently than CVS despite its ability to yield results sooner. This is due to its ease of use and safety for both mother and child. Compared to 1 in 100 with CVS, the number of miscarriages rate after amniocentesis is approximately one in five hundred.
How long does CVS pregnancy test take?
The CVS pregnancy test process requires between ten and fifteen minutes to get the tissue from the placenta specimen called chorionic villi. It usually takes between seven and fourteen days for the complete findings of the chromosomal study to be obtained, indicating if genetic anomalies were found.
Precautions to be taken after CVS test.
For a couple of days following the CVS procedure, the mother should refrain from physically demanding activities and sexual activity. Even while cramps and spotting are common, you should notify your doctor if you experience any significant discomfort, blood loss or fluid leaking. It may be necessary to arrange follow-up ultrasonography tests to make certain the pregnancy is developing healthily.
How long does chorionic villus sampling results take?
For genetic evaluation, the tissue specimen obtained during chorionic villus sampling is delivered to a lab. Final test results can take anywhere from 7 to 14 days, based on the facility and whether more testing, such as taking out DNA, is needed. Expected timescales should be discussed in advance with your physician.
CVS vs amniocentesis – which is better?
There isn’t a clear-cut superior choice. The mother’s choices, dangers, and timing all play a role in the decision between CVS vs. amniocentesis. CVS is an option for women over 35 who want early treatment. Younger women could put off amniocentesis if they would rather not take on greater risks from CVS testing.
Chorionic villus sampling vs amniocentesis
Chorionic villus the sampling process, which is performed early between 10 and 13 weeks, looks at cells from the growing placenta. Amniocentesis, which examines the amniotic fluid around the developing baby, is only possible when the fetus has been growing for 15 weeks. The accuracy of both procedures in detecting genetic anomalies is comparable.
Difference between CVS and amniocentesis?
In contrast with 2nd trimester amniocentesis, CVS carries a greater chance of miscarriage however can yield results before the end of the first trimester. CVS is performed via the abdomen with the use of ultrasound imaging. During an amniocentesis amniotic fluid is extracted by passing a tiny needle through the abdomen.
Spotting, cramps, and discomfort are possible side effects of both treatments. After CVS, the chance of experiencing a fetal loss or miscarriage remains 1 in 100 as opposed to 1 in 500 with amniocentesis.
Which procedure involves withdrawing amniotic fluid between the 15th and 18th weeks of pregnancy?
The procedure known as amniocentesis, which is carried out between 15 and 18 weeks of pregnancy, entails passing a hollow needle through the abdominal cavity and into the amniotic sac that surrounds the growing embryo. To look for chromosomal abnormalities, about 15-20ml of amniotic fluid is extracted and examined.
