Genetic counseling in pregnancy is a health service that helps you understand how genetics may affect you, your pregnancy, and your baby. It focuses on explaining medical information in clear, plain language and supporting you as you make your own choices about testing and next steps.
Genetic counselors don’t diagnose genetic conditions or change a baby’s genes. They can be a part of your pregnancy care team and can help you feel more informed and prepared, but do not replace your routine obstetric care.
Genetic counseling during pregnancy is usually provided by a prenatal genetic counselor, a healthcare professional with specialized training in genetics and counseling. In some settings, medical geneticists or other medical professionals with genetics expertise may also provide genetic counseling. Genetic counseling sessions may happen before or during pregnancy, or after birth, depending on your questions and needs.
What does a genetic counselor do?
During a visit, the genetic counselor may ask detailed questions about:
- Your health
- Your partner’s health
- Your family history on both sides
Sometimes they may draw a family tree (called a pedigree) to map out relatives with genetic conditions, birth differences, learning differences, previous miscarriages, previous stillbirths, or early deaths. This helps them estimate the likelihood that certain genetic conditions could affect your pregnancy.
The genetic counselor will also review any test results you already have, such as carrier screening, prenatal screening, or ultrasound findings. They explain what each result means and does not mean, in a simple to understand way.
Together, you and the genetic counselor discuss whether additional screening or diagnostic tests might be useful based on your situation and values.
What happens during an appointment?
Most appointments last about 30–60 minutes, though the timing can vary. Visits may be in person, by phone, or by video, depending on the facility. You can usually attend alone, with a partner, or with another support person.
A typical visit includes:
- Clarifying your questions and concerns
- Reviewing your medical and pregnancy history
- Reviewing your partner’s medical history and your family histories
- Explaining any relevant conditions or risks
- Discussing available testing options, if applicable
- Talking through possible outcomes and next steps
At the end of the visit, the genetic counselor usually summarizes key points, checks that your questions have been answered, and makes a plan for follow‑up if needed.
Emotional support and decision-making
Genetic information can raise questions and emotions, including worry, guilt, confusion, or relief. Genetic counselors are trained to address both medical and emotional aspects of care. They provide space to talk about your feelings, values, cultural or spiritual beliefs, and family context while you consider your options.
Importantly, a genetic counselor does not tell you what decision to make or what is “best.” Instead, they offer balanced information, explore your preferences, and support whatever informed decision you make.
When is genetic counseling used in pregnancy?
Genetic counseling can be helpful in many situations. Common reasons for referral during pregnancy include:
- A positive or high‑risk prenatal screening result
- Ultrasound findings that could be related to a genetic condition
- A previous child or pregnancy with a genetic condition
- A personal or family history of a known genetic condition
- Concerns about medication, substance, or infection exposures in pregnancy
Some people seek genetic counseling even without a specific concern, simply because they want more information about genetics and testing in pregnancy. Genetic counseling can also take place before pregnancy (also called preconception genetic counseling) to review risks, carrier status, and reproductive options.
How does genetic counseling relate to prenatal tests?
Genetic counseling often happens before or after prenatal genetic tests.
Before testing, a genetic counselor can explain:
- What each test looks for
- How and when the test is done
- What a normal or abnormal result might mean
- How results could affect pregnancy decisions or planning
After testing, genetic counseling can help interpret results from:
- Screening tests (such as serum screening or cell‑free DNA testing)
- Diagnostic tests (such as chorionic villus sampling or amniocentesis)
- Carrier screening results
Genetic counselors emphasize that screening tests estimate likelihood and do not diagnose a condition. Diagnostic tests can usually determine whether a specific genetic condition is present, but they also have risks and limitations. The genetic counselor’s role is to help you understand these options so you can make choices that feel right for you.
Benefits and limitations of genetic counseling
Genetic counseling offers several potential benefits:
- Clear explanation of complex genetic information
- More time to ask questions
- Support with decision‑making about screening and diagnostic testing
- Help communicating with other members of your healthcare team
- Connection to additional resources or specialists when needed
There are also limitations. Genetic counseling cannot predict everything about a pregnancy, and it cannot guarantee that a baby will or will not have a specific condition. Sometimes, even with genetic counseling and testing, uncertainty remains. Access to genetic counseling may vary based on where you live and your insurance coverage, though telehealth options are expanding.
How Can I Access Genetic Counseling?
You can usually access genetic counseling through a referral from your obstetrician, midwife, or primary care provider. Some clinics and telehealth services also accept self‑referrals, especially for preconception counseling or carrier screening questions.
Genetic counselors often work in maternal‑fetal medicine (MFM) clinics, hospital genetics departments, fertility clinics, larger health systems, and testing laboratories.
If you are unsure whether genetic counseling is available in your area, you can ask your prenatal care provider or check online directories from professional genetics organizations. If you are interested in genetic counseling, it is reasonable to ask for a referral at any point in your pregnancy, even if you have not had any abnormal test results.
Unity offers access to a team of board-certified genetic counselors who can help individuals understand their options, screening results, and discuss next steps. Appointments can be scheduled through the patient portal, on the Unity website, or by contacting Client Services directly.
