Genetic screening is an important part of prenatal care that provides early insight into your baby’s health and the potential for inherited conditions. These simple, noninvasive tests identify whether you or your partner carry genes that could affect your baby or whether your pregnancy has an increased risk for certain chromosomal abnormalities.
With easy blood testing and personalized guidance, MyOBGYN in Las Vegas helps you make informed decisions throughout your pregnancy journey.
What Is Genetic Screening?
Genetic screening includes tests that detect inherited or spontaneous genetic changes. These screenings fall into two main categories:
1. Carrier Screening
Carrier screening checks whether you or your partner carry genes for certain inherited conditions that can be passed to your baby. Many people are carriers without knowing it, as they often have no symptoms.
2. Chromosomal Screening
Chromosomal screening evaluates the baby’s risk for chromosomal abnormalities such as Down syndrome (trisomy 21), trisomy 18, or trisomy 13. It includes non-invasive options like NIPT and first-trimester screening, usually offered early in pregnancy.
Carrier Screening
Carrier screening can be done before or during pregnancy with a simple blood test. If both parents carry the same genetic condition, the baby may have a higher chance of inheriting it.
Common conditions included in carrier screening:
- Cystic fibrosis
- Spinal muscular atrophy (SMA)
- Tay-Sachs disease
- Sickle cell anemia
- Thalassemia
- Fragile X syndrome
Expanded carrier panels may test for additional conditions depending on your family background and medical history.
Chromosomal Screening
Chromosomal screening focuses on conditions related to chromosome number or structure. Options may include:
- Non-Invasive Prenatal Testing (NIPT): Screens fetal DNA in maternal blood for trisomies and sex chromosome conditions starting at 10 weeks.
- First-trimester screening: Combines a blood test with an ultrasound between 11 and 14 weeks.
- Second-trimester quad screen: A blood test done between 15 and 20 weeks to assess risk for Down syndrome, neural tube defects, and other anomalies.
These tests are optional and designed to provide information, not a diagnosis.
Who Should Consider Genetic Screening?
Genetic screening is available to all pregnant patients and is particularly recommended if you:
- Have a family history of genetic or chromosomal conditions
- Are age 35 or older at delivery
- Belong to an ethnic group with a higher carrier frequency for certain disorders
- Had abnormal results in a prior pregnancy
- Are adopted or have limited family health history
Your provider will recommend the right tests and timing based on your health and preferences.
What If My Results Are Abnormal?
If your results indicate an increased risk, additional testing and support are available. Next steps may include:
- Diagnostic testing such as chorionic villus sampling (CVS) or amniocentesis
- Genetic counseling for result interpretation and decision-making
- Referral to specialists for advanced prenatal or pediatric care
