Why This Test Is Done

Your healthcare provider may recommend this test if you or your partner have a family history of genetic disorders, if you’re carrying a pregnancy at high risk for certain conditions, or if you’re considering genetic counseling. It can also be done if you’re planning a pregnancy and want to understand potential risks before conception.

How the Test Works

A small blood sample is taken from you or your baby (if applicable). The DNA is extracted and analyzed for specific genetic mutations or variations linked to prenatal or congenital conditions. The results help determine if certain genetic risks are present.

What the Results Mean

Results can indicate whether you carry specific genetic mutations that may affect your baby. If mutations are found, your healthcare provider will discuss next steps, which may include additional testing, genetic counseling, or planning for pregnancy management. Results may also help guide decisions about family planning or prenatal care.

Common Conditions Evaluated

This test may screen for a range of genetic conditions, including chromosomal abnormalities, single-gene disorders, or other genetic syndromes. The exact conditions evaluated depend on the specific genetic panel ordered, which could include conditions like Down syndrome, cystic fibrosis, spinal muscular atrophy, or others based on your risk factors.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Genetic testing in prenatal care helps identify potential genetic risks early, allowing for informed decision-making. Early detection can lead to better prenatal monitoring, tailored treatment plans, or interventions to support fetal health. It also provides clarity for families about genetic risks and helps guide reproductive choices if needed.

Frequently asked questions

What does a positive result mean?
A positive result means that certain genetic variations linked to specific conditions were detected in your sample. This does not always mean your baby will have a condition, but it indicates an increased risk. Your healthcare provider will discuss the implications with you and help determine next steps, such as further testing or genetic counseling.
How long does it take to get results?
Test results typically take 2 to 4 weeks to complete, depending on the complexity of the genetic panel and laboratory processing times. Your healthcare provider will contact you once results are available.
Can this test be done during pregnancy?
Yes, this test can be performed during pregnancy, often as part of prenatal screening or diagnostic testing. It may also be recommended before pregnancy if you’re planning to conceive and want to assess genetic risks.
