Discharge Instructions for Amniocentesis

You had an amniocentesis. This is a prenatal test. It helps you learn whether a fetus has health problems. The test is most often done between the 15th and 20th week of pregnancy. It is also done to check the condition of the lungs of a baby who will be delivered several weeks early.

Home care

  • Limit your activity for 24 to 48 hours after the procedure.

  • Know the risks involved with amniocentesis. This can help you recognize if you are having complications. Make sure you understand the following risks:

    • Loss of blood

    • Infection

    • Harm to the baby from the needle

    • Harm to the placenta or cord from the needle

    • Premature breaking of the amniotic sac

    • Premature labor or contractions

    • Miscarriage

  • Don’t be alarmed if you have some brief, mild cramping. This is normal.

Follow-up

Make a follow-up appointment with your healthcare provider. Our staff will give you directions.

When to call your healthcare provider

Call your healthcare provider right away if you have any of the following:

  • Fever above 100.4°F (38.0°C) or chills

  • Bright red vaginal bleeding or a smelly discharge

  • Contractions or severe cramping

  • Liquid vaginal discharge that doesn’t stop

  • Redness or swelling where your healthcare provider inserted the needle

  • Decreased movement of the baby if the amniocentesis is done late in pregnancy
