Karyotyping (CVS/Amniotic Fluid)

Karyotyping involving Chorionic Villus Sampling (CVS) or Amniotic Fluid is a genetic test that analyzes the chromosomes of a fetus. Chromosomes are the structures in cells that carry genes. Normally, each human cell contains 46 chromosomes. However, if there is an abnormal number or structure of chromosomes, it can lead to genetic disorders and developmental abnormalities.


  • Test NameKaryotyping (CVS/Amniotic Fluid)
  • Sample TypeChorionic Villus Sample (CVS)/Amniotic Fluid
  • Preparations RequiredThe pregnant person should follow the doctor’s instructions. Typically, no special dietary restrictions are required, but a full bladder may be needed for certain procedures.
  • Report Time21 days

Chorionic villi are tiny finger-like structures found in the placenta, whereas amniotic fluid is the fluid surrounding the fetus inside the womb. CVS involves collecting a sample of these chorionic villi, while amniocentesis involves taking a sample of the amniotic fluid. Both of these samples contain the fetal cells needed for karyotyping.

This procedure is generally performed during pregnancy to check for genetic disorders in the fetus. It is often recommended for individuals who have a family history of genetic disorders, are of advanced maternal age, or have had abnormal results from other prenatal tests.

Frequently Asked Questions

Karyotyping using CVS or Amniotic Fluid is essential in detecting genetic disorders and chromosomal abnormalities in a fetus. This allows for informed decisions regarding the pregnancy and preparations for any specialized care that might be needed after birth.

No, fasting is not required for this test. However, it's essential to follow the doctor’s specific instructions, which may include having a full bladder.

No specific preparation is needed, but the pregnant person should ensure they follow any instructions provided by the doctor. This might include avoiding certain activities or medications before the test.

This test is usually performed between the 10th and 13th week of pregnancy for CVS, and between the 15th and 20th week for amniocentesis. Your doctor will recommend the best timing based on your health and medical history.

Karyotyping with CVS/Amniotic Fluid provides detailed information on the number, size, and structure of the chromosomes in the fetus. It can identify conditions such as Down syndrome, Edwards syndrome, and other genetic disorders.

This test is usually performed only once during a pregnancy when there is a specific concern or risk factor for genetic disorders.

Normal results would show 46 chromosomes, with a specific arrangement and structure. Any deviation should be discussed with a doctor for interpretation and guidance.

The person should follow the doctor's instructions before the test. After the procedure, it’s advisable to rest and avoid any strenuous activities for a couple of days.

Chromosomal abnormalities are generally inherited or occur randomly during fetal development. They are not typically influenced by environmental factors.

A geneticist or a doctor specializing in genetics should be consulted for proper counseling and guidance in case of abnormal results.

For CVS, a thin tube or needle is used to collect tissue from the placenta, either through the cervix or the abdomen. For amniocentesis, a needle is inserted into the uterus to collect amniotic fluid.

There are some risks, including miscarriage, infection, and leaking of amniotic fluid. It is important to discuss the risks and benefits with the doctor to make an informed decision.

If an abnormality is detected, further testing may be recommended. Genetic counseling will be provided to discuss the results, the implications, and the options available regarding the pregnancy.

It usually takes between 10 to 14 days to receive the results from this test.

No, this test is primarily aimed at detecting chromosomal abnormalities and may not detect all genetic disorders, especially those caused by mutations in a single gene.

Karyotyping through CVS or Amniotic Fluid is an invaluable tool in prenatal care, allowing for the early detection of genetic disorders. This knowledge enables parents-to-be and doctors to make informed decisions regarding the pregnancy and prepare for the birth and care of the child. Understanding the benefits, risks, and limitations of the procedure is important. Proper counseling and support are crucial, especially in cases where abnormalities are detected. This test plays a vital role in ensuring the well-being of both the mother and the child.
