What is Prenatal Diagnosis?

Prenatal diagnosis involves specialized testing during pregnancy to detect genetic, chromosomal, or structural abnormalities in the baby. These tests provide critical insights that guide medical care before and after birth. Prenatal diagnosis is recommended between 15 and 22 weeks of pregnancy and is vital in promoting a healthy pregnancy and delivery experience.

Who Needs Prenatal Screening?

Prenatal screening is recommended for all pregnancies, but it is particularly beneficial for:

• Women over 35: Increased age raises the risk of chromosomal abnormalities.
• High-risk pregnancies: Those with pre-existing conditions like diabetes or phenylketonuria.
• Family history of genetic disorders: Identifies potential hereditary conditions.
• Abnormal screening results: Further testing is often advised to confirm findings.
• History of pregnancy complications: Women with prior miscarriage, preterm labor, or Cesarean deliveries.

What are Prenatal Services?

Prenatal services play a critical role in ensuring the health of both mother and baby. They help:

• Monitor your baby’s development and growth.
• Detect and address potential complications early.
• Provide essential education on pregnancy and postpartum care.
• Offer emotional and physical support throughout your journey.

At PVHC, we are committed to providing personalized care and guidance to help you enjoy a healthy, stress-free pregnancy.

What are the Types of Prenatal Screening Tests?

The Premier Family Medicine physicians at PVHC recommend evidence-based, non-invasive prenatal screening tests for all pregnant women. These tests are designed to provide vital information about your baby’s health and detect potential genetic or chromosomal abnormalities.

First-Trimester Screening: Blood Test and Ultrasound

This screening combines a blood test and an ultrasound to measure nuchal translucency, the clear space at the back of your baby’s neck. An abnormally large measurement can indicate chromosomal conditions such as Down syndrome.

Second-Trimester Quad Screen

This blood test measures the levels of four specific substances in the mother’s blood. The results can help:

• Detect the risk of chromosomal abnormalities, such as Down syndrome.
• Identify neural tube defects like spina bifida, a serious condition affecting the brain or spinal cord.

Non-Invasive Prenatal Testing (NIPT)

NIPT is a blood test that analyzes fetal DNA circulating in the mother’s blood. It is highly effective in detecting chromosomal abnormalities such as:

• Down syndrome (Trisomy 21).
• Edwards syndrome (Trisomy 18).
• Patau syndrome (Trisomy 13).
• Sex chromosome disorders (e.g., Turner Syndrome).

Prenatal Genetic Carrier Screening

This test identifies whether parents carry genetic mutations that could be passed to their baby, helping assess the risk of inherited conditions like cystic fibrosis or sickle cell anemia.

Advanced Diagnostic Testing for Those With Abnormal Results

If abnormalities are detected during screening, you may be referred to the Pomona Valley Hospital Medical Center (PVHMC) perinatal team for additional diagnostic testing:

Amniocentesis

This procedure involves using a thin needle to remove a small amount of amniotic fluid from the sac surrounding your baby. The fluid is analyzed for chromosomal abnormalities, genetic disorders, and neural tube defects.

Chorionic Villus Sampling (CVS)

CVS uses a thin needle to collect a small tissue sample from the fetal part of the placenta. This tissue contains the baby’s genetic material and can be analyzed for chromosomal abnormalities and genetic disorders.

Both tests are performed carefully to ensure the safety of the mother and baby and to provide accurate diagnostic information.

At PVHC, our prenatal screening and diagnostic services are designed to give you peace of mind and empower you with the knowledge you need for a healthy pregnancy.

Does Insurance Cover Prenatal Diagnosis and Genetic Testing?

Most major insurance plans cover prenatal testing, especially for high-risk pregnancies. Even for low-risk pregnancies, many tests are included in standard coverage. The cost of testing can vary, so we encourage patients to consult their insurance provider or our staff to fully understand their benefits.

What is Considered a High-Risk Pregnancy?

Pregnancy is classified as high-risk when factors increase the chance of complications for the mother or baby. Common risk factors include:

• Advanced maternal age (35 or older).
• A history of miscarriage, preterm labor, or Cesarean delivery.
• Pre-existing medical conditions such as diabetes or high blood pressure.
• Abnormal results from early screening tests or ultrasounds.
• A family history of genetic disorders.

At PVHC, our perinatal specialists collaborate with families to provide the highest level of care for high-risk pregnancies.

• Provide information on healthy lifestyle choices, such as nutrition and exercise.
• Screen for potential health conditions, such as gestational diabetes and anemia.

What is the role of prenatal vitamins, and do I need them?

Prenatal vitamins are essential for providing your baby with the nutrients for healthy development. They typically contain folic acid, iron, and other essential vitamins and minerals. It's important to consult with your healthcare provider to determine the best prenatal vitamin for your specific needs.

When should I start prenatal care?

It's ideal to start prenatal care as soon as you know you're pregnant. Early prenatal care allows your healthcare provider to assess your overall health, identify any potential risks, and provide guidance on healthy lifestyle choices throughout your pregnancy.
