How does getting an ultrasound help?
Usually, there are two routine scans during pregnancy. Sometimes it can be more than 2 depending on your situation. The first scan can be an exciting moment as you and your partner catch the first glimpse of your baby. Scans are screening tests that your doctor uses to see your baby through sound waves which creates visual images of the uterus, baby and placenta that can be seen on a monitor. Information on the progress of your pregnancy and baby's well-being are derived from these scans.
What is CVS testing?
This is carried out during the first trimester, when the doctor might have doubts about the foetus having any chromosome or biochemical abnormalities. This diagnostic test involves a biopsy of the chorionic villi. This test is used to determine specific conditions like Down's syndrome, Cystic fibrosis, Thalassaemia, etc.
When does one usually have to undergo a CVS test?
You may qualify for CVS if you:
- are over 35
- have or had a child affected by a chromosomal disorder
- have a family history of one of these conditions
- have an 'increased risk' blood test result
