Amniocentesis Karyotyping is a genetic test performed to examine the number and structure of a fetus’s chromosomes. This test is typically conducted during pregnancy and can assist in diagnosing chromosomal disorders in the fetus.
Why is Amniocentesis Karyotyping performed?
- Family History: If you or your partner have a history of chromosomal disorders in your family, your doctor may recommend this test.
- Maternal Age: Women over the age of 35 are at higher risk of having a fetus with chromosomal disorders.
- Screening Test Results: If initial prenatal screening tests indicate a high risk of chromosomal disorders, your doctor may suggest this test.
- Abnormal Ultrasound Findings: If the fetal ultrasound shows abnormal signs, your doctor may recommend this test.
How is Amniocentesis Karyotyping performed?
- A thin needle is inserted through the mother’s abdomen into the uterus.
- A small amount of amniotic fluid, in which the fetus is floating, is collected.
- The fetal cells present in the amniotic fluid are tested to examine the number and structure of the fetus’s chromosomes.
Results of Amniocentesis Karyotyping:
- Normal: The number and structure of the fetus’s chromosomes are normal.
- Abnormal: The number or structure of the fetus’s chromosomes is abnormal. This may indicate chromosomal disorders such as Down syndrome, Edwards syndrome, or Patau syndrome.
Risks of Amniocentesis Karyotyping:
Amniocentesis is a relatively safe procedure, but like any medical procedure, it carries some risks. These risks include miscarriage, infection, and bleeding.
