This is a guest post from our sponsor Natera. From conception to delivery, Natera is pioneering next generation accuracy and reliability with tests ranging from preimplantation genetic diagnosis for IVF to breakthrough advances in the field of non-invasive prenatal testing (NIPT) and we are happy to share their wisdom on Genetic Testing and Miscarriage with you.
After a pregnancy loss and asking “Why me?”, the next step might be genetic testing.
Then you’re faced with questions like:
- What type of genetic testing is available for miscarriages? Is it right for me?
- How can chromosome testing help? Can it help me?
Genetic testing actually refers to many different types of testing. For pregnancy loss, the most useful type of test to perform is chromosome testing. This testing looks for extra or missing chromosome material. Because so many miscarriages are caused by chromosome errors, this testing can often find the reason for a pregnancy loss.
Your doctor may give you options about what type of chromosome testing to have done. The traditional method is called karyotyping. Newer methods include advanced technologies such as microarrays. Both types of testing require a simple blood draw..
Microarray testing has some advantages over karyotyping including faster test results, much higher chance to actually obtain results, and the ability to give you more information. Natera can help!
Chromosome Testing – How can it help?
If a chromosome abnormality is found, the result can help answer the questions: “What caused my miscarriage” and “Will this happen to me again?” Most of the time, the answer to ‘Will it happen again’ is no. Most chromosome abnormalities in a pregnancy are not inherited and have a low chance of reoccurance. Sometimes, a specific chromosome finding in a miscarriage alerts your doctor to do more testing to rule out a chromosome problem in your family that puts you at risk of having further miscarriages or a child with birth defects due to a chromosome syndrome.
If a chromosome abnormality is found, it can prevent the need for other, sometimes expensive, studies your doctor might order to investigate the cause of the miscarriage.
Lastly, knowing the reason for a pregnancy loss can help a couple start the emotional healing process, moving past the question of “Why me?” and move on to the question of “What’s next?”
