What is an amnio?

Amniocentesis is a procedure in which amniotic fluid is removed from the uterus for testing or treatment. Amniotic fluid is the fluid that surrounds and protects a baby during pregnancy. This fluid contains fetal cells and various proteins.

When is CVS done?

CVS is usually done between the 10th and 12th weeks of pregnancy. Unlike amniocentesis (another type of prenatal test), CVS does not provide information on neural tube defects, such as spina bifida.

When was amniocentesis first used?

Amniocentesis, the first available prenatal chromosomal diagnostic testing option, was first described in the 1950s. Amniocentesis has become increasingly safe and is now used for several purposes, including genetic screening and infectious evaluations.

What are the indications for amniocentesis?

The most common indication for amniocentesis is a “high risk” result from a first trimester screening test, or a previous pregnancy affected by a genetic condition. The fetal cells that are obtained can be tested for various chromosomal conditions, such as Down’s syndrome, Edward’s syndrome and/or Patau’s syndrome.

What is CST in pregnancy?

The contraction stress test helps predict how your baby will do during labor. The test triggers contractions and registers how your baby’s heart reacts.

Can amniocentesis tell gender?

An amniocentesis is the most accurate way to determine the baby’s gender before birth. An amniocentesis can also be done during the third trimester of the pregnancy to determine if the baby’s lungs are mature enough where an early delivery may be warranted.

Does an amniocentesis hurt?

Amniocentesis is not usually painful, but you may feel uncomfortable during the procedure. Some women describe experiencing a pain similar to period pain or feeling pressure when the needle is taken out.

How much fluid is removed during amniocentesis?

Amniocentesis is a procedure in which your doctor removes a small amount of amniotic fluid from your uterus. The amount of fluid removed is typically no more than 1 ounce. Amniotic fluid surrounds your baby in the womb.
