Amniocentesis is a prenatal diagnostic test used to determine whether or not a baby has any genetic disorders. It involves removing a small amount of amniotic fluid from the uterus using a needle. The fluid is then checked for chromosomal abnormalities and other congenital disabilities in a lab.
Amniocentesis is a safe and accurate test, and it can provide valuable information to parents-to-be about their unborn child. Professionals recommend amniocentesis procedures for women 35 years of age or older as they are at a higher risk of having a baby with a genetic disorder. The process can happen between weeks 15 and 20 of pregnancy and as early as week 12.
Doctors advise women who have had a previous child with a genetic defect to have an amniocentesis. In some cases, the test may be performed earlier in pregnancy if there is reason to believe that the baby has a genetic disorder.
Why Is It Done?
Amniocentesis happens for two primary reasons:
- Screen for genetic disorders: This procedure can help identify whether or not the baby has any genetic disorders. This information can be helpful for parents who may want to make decisions about their pregnancy.
- Diagnose fetal infections: In some cases, this procedure may diagnose infections in the fetus. Doctors can treat these infections with antibiotics, which can help prevent serious complications for the baby.
What to Expect During the Procedure
Before the procedure, the doctor will likely do a physical exam and an ultrasound to determine the baby’s location and placenta. A local anesthetic will be injected into the skin to numb the area. The doctor will then insert a needle through the abdomen and the uterus. A small amount of amniotic fluid is acquired and then sent to a lab for analysis. The whole procedure takes about 30 minutes and is on an outpatient basis.
What to Expect After the Procedure
After your procedure is complete, you will likely go home and rest for the remainder of the day. You may experience some cramping or bleeding after the process, but this is usually mild and goes away quickly. It is important to avoid strenuous activity and sexual intercourse for the next 24 hours. You should also avoid using tampons or douching during this time. Your doctor will likely give you instructions on caring for yourself at home. It is essential to follow these instructions carefully to avoid any complications.
Risks of Amniocentesis
There are some risks associated with this procedure, but they are rare. These risks include:
- Infection: There is a small risk of infection after the procedure. Professionals may reduce this risk by having the procedure done in a clean and sterile environment.
- Bleeding: There can be a slight risk of bleeding after the procedure. Avoiding strenuous activity and using a sanitary pad to absorb any blood present reduces the risk.
- Damage to the fetus: The needle may damage the fetus in rare cases. This risk is usually very low when a trained and experienced doctor performs the procedure.
- Leaking of amniotic fluid: In rare cases, the needle may puncture the amniotic sac and cause the leakage of amniotic fluid. It can lead to complications such as premature labor.
What Are the Next Steps?
If you are considering amniocentesis, it is crucial to speak with your healthcare provider about the risks and benefits of the procedure. It would help if you also asked about other prenatal diagnostic tests. Once you have decided, your healthcare provider will help you schedule an appointment.
