All You Should Know About CVS

 


An example of a genetic test performed during pregnancy is chorionic villus sampling or CVS testing. It can identify some medical issues that the fetus may have. The test findings from CVS are pretty precise. You can use CVS and amniocentesis, another prenatal test, to assist in crucial medical decisions. If necessary, your healthcare provider helps you decide what to do next.  


What is Chorionic Villus Sampling?  


The prenatal test known as chorionic villus sampling (CVS) is one of many prenatal diagnoses. To check for diseases like Down syndrome in the developing fetus, you may decide to have this genetic testing done while you are pregnant. The gender of the unborn can also be determined with the help of this test.  


The placenta, an organ that develops during pregnancy and feeds the fetus, is the source of cells used in CVS testing at chorion villus biopsy center in Mumbai. Chorionic villi are the cells that your healthcare provider removes. Since they are created from fertilized eggs, they typically share the same genes as the developing fetus.  


Difference Between CVS Testing And Amniocentesis  


Amniocentesis and CVS testing are both examples of prenatal diagnostic procedures. However, healthcare professionals carry them out at various stages of pregnancy. Amniocentesis is performed later in the pregnancy than CVS testing. A CVS is often conducted between 10 and 13 weeks of pregnancy, whereas amniocentesis is typically done around 15 weeks. Additionally, the things that they test for vary somewhat. Amniocentesis, for instance, can check for problems in the neural tube, which develops into your baby's brain and spinal cord. These conditions are not detectable by CVS. Spina bifida is an illustration of one of these flaws. Your doctor can discuss your risk with you and suggest either or not of these tests.  


When Are CVS Tests Conducted?  


You get a CVS test when you are between ten and thirteen weeks pregnant.  


Who Needs CVS Testing?  


Testing for CVS is not a standard component of prenatal care. The test can identify genetic disorders in the early stages of pregnancy. If you have certain risk factors, abnormalities found on early ultrasounds, or abnormal genetic (as opposed to blood) screening results, your healthcare professional might suggest this option. But you also have the option of skipping the test.  


What Illnesses Or Conditions Are Detected By Chorionic Villus Sampling?  


Certain genetic illnesses, such as chromosomal disorders, can be found with the aid of CVS. Fetal DNA is stored in these cell structures. CVS can identify chromosomes that are extra, missing, or that have had severe structural alterations. Birth abnormalities and other issues may result from these genetic alterations.  


Does CVS Testing Detect All Congenital Disabilities?  


CVS does not catch some birth abnormalities. For instance, ultrasound tests for most birth abnormalities cannot identify spina bifida, cleft lip and palate, or cardiac conditions when you're about 18 to 20 weeks pregnant.  

If you have CVS, you might want to get an AFP blood test later in your pregnancy. AFP performs a non-CVS screening for neural tube abnormalities.  


What Questions Should I Put To My Doctor Concerning CVS Testing?   


If you are expecting, think about inquiring with your provider:  

  • Do I need to have prenatal testing?  
  • Am I at a high risk of giving birth to a child with a chromosomal or another genetic defect?  
  • Is CVS better for me than amniocentesis?  
  • How likely is a miscarriage?  
  • What issues should you watch out for following a CVS procedure?  

A note from Treetop  


During pregnancy, chorionic villus sampling, or CVS testing, is performed to determine whether the fetus has specific genetic issues. You're not required to undergo CVS testing. If you decide to have it, you will do so while you are between 10 and 13 weeks pregnant. The test is exceedingly accurate, safe, and only a little uncomfortable. You can use the results of CVS testing to guide significant medical decisions. Speak to your healthcare practitioner if you're worried you might give birth to a child with a genetic disorder. They can aid you in determining whether CVS testing is appropriate for you. If you are still looking or more information on the same, you can visit chorion villus biopsy center in Mumbai!

Everything About Multifetal Pregnancy Reduction

  What is Multifetal Pregnancy Reduction? When you have more than one fetus, multifetal pregnancy reduction (MPR) is a technique that aims to reduce the overall number of foetuses. If you're at high risk, this can improve your chances of having a safe pregnancy and assist the surviving fetus or fetuses survive. It's typically done between 11 and 14 weeks of pregnancy after genetic testing has been done to see if there are any issues. Because MPR can be difficult for both you and your partner to deal with, it's critical to work with a maternal fetal medicine specialist who can help you deal with what is often a very emotional and complex situation. How Is It Performed? There are some hazards associated with carrying a pregnancy with more than one fetus, and undergoing a multifetal pregnancy reduction treatment is one effective option to lower your risks. Although deciding to have one and navigating the procedure might be stressful, it's critical to understand your optio...

Know About CVS & Their Obstacles

Image
    Chorionic villus sampling (CVS) is a prenatal test used to determine congenital disabilities, diseases in genes, and other such obstacles during pregnancy. When the trial takes place, a little sample of cells, i.e., chorionic villi, is taken from the placenta, which is attached to the uterus wall. Chorionic villi are the small parts of the placenta formed from the fertilized egg to have the same genes as the baby.   A CVS test aims to detect congenital disabilities or genetic diseases in the early stages of pregnancy, which might become the risk factors for having a baby. Many blood screening tests for such congenital disabilities are usually less reliable if you have twins. However, the risk of CVS is higher in the woman carrying twins. With the help of CVS, you can get your doubts cleared.    What are the risks of CVS?    CVS might carry a slight inflated risk of miscarriage compared to amniocentesis because this procedure will occur ...
