Spina Bifida Blood Test in Pregnancy FAQs
Spina Bifida Blood Test in Pregnancy FAQs Expecting moms often have many questions about prenatal tests. One key test is the maternal blood screening for spina bifida. This test checks for possible neural tube defects in the baby. We’ll cover the most common questions about this test, using info from trusted sources like the American Pregnancy Association and the Centers for Disease Control and Prevention (CDC).
This test is vital for your and your baby’s health. It helps you make smart choices during pregnancy. So, let’s dive into the details.
What is Spina Bifida?
Spina bifida is a birth defect where the spinal cord and its covering don’t fully develop. It happens when the fetal spine doesn’t close right during the first month of pregnancy. This can lead to physical and intellectual disabilities.
Spina bifida comes in different forms, from mild to severe. The main types are:
- Spina Bifida Occulta: This is the mildest type, hidden under skin.
- Meningocele: A moderate type where a fluid sac comes out through the back but doesn’t have the spinal cord.
- Myelomeningocele: This is the most severe, where parts of the spinal cord and nerves come out through the spine, causing big disabilities.
The type and location of the defect affect how much it impacts a person. Higher up on the spine usually means more severe effects.
Spina bifida affects about 1,500 to 2,000 pregnancies each year in the U.S., says the Spina Bifida Association. The exact causes are still being studied, but it might be due to genes, diet, and environment.

Purpose and Importance of Spina Bifida Blood Test During Pregnancy
The Spina Bifida Blood Test is key in pregnancy care. It’s vital for prenatal health. It helps the parents and the baby a lot.
Early Detection Benefits
Finding spina bifida early is a big plus. It lets doctors help before it gets worse. This means a better chance for a good outcome.
Knowing early gives parents time to plan for prenatal health and pregnancy care. This helps them make smart choices.
Health Implications for the Baby
A baby with spina bifida might have trouble walking. They could also have hydrocephalus or learning issues. Early tests help make a plan to help them.

Parental Preparation
Early test results help parents get ready, mentally and emotionally. They can learn about the condition and find support. This helps them work with doctors for the best care.
How is the Spina Bifida Blood Test Conducted?
The spina bifida blood test measures alpha-fetoprotein (AFP) in the mother’s blood. It’s done in the second trimester of pregnancy. This is part of the maternal serum screening.
A small blood sample from the mother is taken. This is usually done between the 15th and 20th weeks of pregnancy. The blood is checked for AFP levels. AFP is a protein made by the fetus that gets into the mother’s blood.
High AFP levels can mean a higher risk of spina bifida. The test results are looked at with other things like the mother’s age and health. This helps understand the risk better.
This gives important info to parents and doctors. It helps them make good choices.
| Test Component | Description |
|---|---|
| Alpha-fetoprotein (AFP) Levels | Measurement of AFP protein produced by the fetus, present in the mother’s blood |
| Maternal Serum Screening | Assessment that includes AFP levels along with other markers in the mother’s blood |
| Risk Assessment Factors | Includes mother’s age, weight, ethnicity, and diabetic status |
| Optimal Timing | Typically conducted between the 15th and 20th weeks of pregnancy |
It’s key for moms-to-be to talk about the AFP test results with their doctor. This helps make smart choices. If needed, more tests can be done to check for neural tube defects.
Who Should Get the Spina Bifida Blood Test?
It’s important to know who should take the Spina Bifida blood test. This test checks for neural tube defects during pregnancy. It looks at the levels of maternal serum AFP. Knowing who is at higher risk helps make better decisions and can lead to better health outcomes.
High-Risk Groups
Some women are more likely to have a baby with spina bifida. These include:
- Family History: Women with a family history of neural tube defects are more likely to have a baby with one. If a previous baby had a neural tube defect, the risk goes up.
- Medication Use: Some medicines can raise the risk of neural tube defects. Women taking these should talk to their doctors about screening tests.
- Diabetes: Women with diabetes before pregnancy are at higher risk for neural tube defects.
General Recommendations
The American College of Obstetricians and Gynecologists (ACOG) says all pregnant women should have the chance to get tested for neural tube defects. This test is key for high-risk groups.
