When considering starting a family, it’s essential to understand the implications of genetic testing. You may have learned in biology about how genes—segments of DNA with specific sequences—can mutate and lead to genetic disorders. According to Dr. Samantha Rivers, a clinical geneticist, carrier testing can help determine if you or your partner are at risk of passing on genetic conditions to your future child. Even if you don’t exhibit symptoms, being a carrier can still put your baby at risk.
Should You Think About Genetic Testing?
If there’s a history of genetic disorders in your family or your partner’s, preconception genetic testing is worth considering. Dr. Mark Johnson, a psychiatrist, emphasizes that certain ethnic groups are more susceptible to specific recessive diseases. For instance, Ashkenazi Jews are at a higher risk for conditions like Tay-Sachs disease, while African Americans may be more prone to sickle cell anemia. If you or your partner have any concerns about your family history, discussing preconception testing with your healthcare provider is advisable.
How Does the Testing Process Work?
The testing procedure is relatively simple. If you’re planning to conceive, schedule a preconception appointment with your OB-GYN. They will review your family and medical history along with your ethnic background to recommend appropriate carrier screenings. You will start with a blood test; if you’re found to be a carrier for a condition, your partner will then be tested. If both of you test positive, a genetic counselor can provide further insights and guide you in making informed choices.
What Types of Tests Are Available?
The American College of Medical Genetics and Genomics suggests testing for a limited number of genetic diseases, including cystic fibrosis and Fragile X syndrome, among others. The tests generally fall into two categories: genotyping, which looks for known mutations, and expanded carrier screening, which checks for a broader range of genetic conditions. Remember, even if you test negative, there’s always a slight chance of having a rare mutation that isn’t screened.

In summary, preconception genetic testing can be a valuable step for couples, especially those with a family history of genetic disorders. By identifying potential risks early, you can make informed decisions about your family’s future.
