CVS DNA Test is usually performed between 10 and 12 weeks of gestation period. Unlike amniocentesis, this test does not give information on neural tube defects, such as the “spina bifida” condition. Because of this, women who choose the CVS technique are also required to have a follow-up blood test which is done between the 16th and 18th weeks of pregnancy to screen for neural tube defects.
There are two types of CVS procedures:
- Transcervical– it is done by inserting a catheter through the cervix into the placenta to get the tissue sample.
- Transabdominal– in this case, the tissue sample is obtained by inserting the needle through the abdomen and uterus into the placenta.
Generally, a CVS procedure follows this process:
- First, your vital signs (heart rate, breathing rate, and blood pressure) will be checked.
- After checking the main signs, an ultrasound will be done to check the fetal heart rate, and the position of the fetus, placenta, and umbilical cord.
Based on the location of the placenta, the CVS procedure will be performed by transcervical process or transabdominal process.
In a transabdominal procedure, it is important to check the bandaged needle site on your abdomen for any bleeding or drainage of fluid. Take assistance from the “facednatest” professionals, who will also you additional or alternate instructions after the procedure, depending on your particular situation.
