If you’re planning to conceive, it’s essential to understand your family’s medical history to assess any potential risks for your future child. However, there are more comprehensive methods available than just reviewing family records: genetic carrier screening is one such option. This test can be performed prior to conception or during pregnancy and identifies whether you and your partner carry genes for certain hereditary conditions, even if you do not exhibit symptoms yourself. Conditions like Tay-Sachs disease or cystic fibrosis may not be apparent but can be passed to your offspring.
Deciding to undergo genetic carrier screening is a personal choice. There are no definitive right or wrong answers regarding whether to pursue this test. Below are key details regarding genetic carrier screening, including what it entails, who should consider it, and how to prepare for testing.
What is Genetic Carrier Screening?
This screening is a blood test that checks for specific genetic disorders. If both partners are carriers of the same recessive gene, there’s a risk that their children could inherit a genetic disease.
Who Should Get Tested?
Couples considering pregnancy, especially those with a family history of genetic disorders or belonging to specific ethnic groups, should think about genetic screening. It’s also recommended for those who have had previous pregnancies with genetic conditions.
Common Genetic Disorders
Some of the most frequently screened conditions include cystic fibrosis, spinal muscular atrophy, and sickle cell disease.
Preparing for the Test
Before taking the test, you may want to gather your family medical history and consult with a healthcare provider to discuss your specific risks.
Testing Process
The screening typically involves a simple blood draw and can be conducted in a healthcare provider’s office or through at-home kits like those available at Make a Mom.
Cost of Screening
Costs can vary widely based on the provider and specific tests performed. Many insurance plans cover some aspects of genetic testing.
Interpreting Positive Results
A positive result indicates that both partners are carriers for a specific genetic condition. This does not mean that your child will definitely inherit the condition, but it does suggest that further testing or counseling may be beneficial.
Genetic Counseling
Couples who receive positive carrier test results should consider genetic counseling. This can provide insight into risks and options moving forward.
