How accurate are CVS pregnancy tests? Let’s learn more about it and its purpose, and safety in this blog post.
Refer to any early pregnancy tests for mothers-to-be and the CVS falls into the list.
The procedure is typically performed by an obstetrician or genetic counselor, and it involves inserting a thin needle or tube through the mother’s abdomen or cervix to reach the placenta.
Purpose of the CVS – early pregnancy test
The purpose of Chorionic Villus Sampling (CVS) is to diagnose genetic abnormalities and chromosomal disorders in a developing fetus during early pregnancy. CVS is typically performed between 11 and 13 weeks of pregnancy and involves taking a small sample of tissue from the placenta.
The cells in this tissue sample can be analyzed for chromosomal abnormalities and genetic disorders such as Down syndrome, cystic fibrosis, and sickle cell anemia.
The results of the CVS test can help parents make informed decisions about their pregnancy, such as whether to continue with the pregnancy or to prepare for a child with special needs.
How accurate are CVS pregnancy tests? Can you trust it?
As mentioned earlier, the CVS testing is approximately 99% accurate. However, CVS testing helps detect only certain genetic diseases.
A CVS test does not diagnose or screen for birth defects such as neural tube defects, which cause abnormal brain and/or spine development in a developing baby.
To screen for or diagnose these and other birth defects, various tests, including an alpha-fetoprotein (AFP) blood test, are used.
Can CVS be inaccurate?
The tests deduced that the CVS procedure does not recommend relying solely on a normal karyotype obtained after direct preparation in pregnancies at high risk for fetal chromosomal abnormality.
Who conducts the CVS procedure and what does it feel like?
Your doctor or midwife will refer you to an obstetric specialist or obstetric imaging specialist. This procedure, however, will require a referral from your healthcare provider.
CVS is slightly painful. During and after CVS, most women experience only minor discomfort, cramping, and period-like pain. Even though the procedure itself only takes a few minutes, you’ll probably be required to wait for about 30 minutes in a waiting area before being allowed to go home.
If you experience vaginal bleeding, severe abdominal pain, a high fever, or unusual discharge from your vagina in the first few days or weeks after the procedure, go back to your obstetrician-gynecologist who performed the scan for further assistance.
What is the price of CVS?
The CVS procedure with the consultation fee may vary among obstetricians. Inquire with your doctor about the costs associated with explaining your specific situation.
