How Genetic Testing in Children or Babies Work?

genetic testing

Genetic testing is a process in which a blood test is conducted to expecting parents with a view to check for abnormalities in genes that could cause diseases in the baby. Many genetic diseases are referred to as recessive disorders, and this means each of parents has to pass an affected gene for the baby to be affected. You can pay for a carrier screening at an ob-gyne’s office using a single blood test. The results are typically released in two weeks, and women are tested first because they are likely to more often see the doctor.

To show you how this process works, here is a comprehensive guideline.

Prenatal testing

There are different types of gene tests that are conducted on babies, one of them being the prenatal testing. In this one, the tests are done to detect changes in the genes of the fetus before birth. This test is provided during pregnancy and helps to reveal if there is an increased risk that the child could have a chromosomal or genetic disorder. In many cases, this genetic test helps to lessen the uncertainty of couples and allows them to plan pregnancy better. Different clinics offer discounts for this procedure, so you only need to find a doctor who allows you to have an offer for the first visit. It should not cost a lot and it’s a necessary procedure that every parent needs to consider.

Diagnostic testing

Diagnostic testing is used as a way to identify a genetic condition, and in different cases, it’s used to verify a diagnosis when there is suspicion a certain condition could occur, based on symptoms and signs. The testing can be performed before or after birth. Results obtained from a genetic testing procedure can influence the health care choices of an individual and could also be useful in enhancing the way a person manages their disorder. In children, it helps to learn about disorders early so as to plan on medication and care.

Who should consider genetic testing?

You should go for genetic testing for your baby if:

  • You are a woman who is aged over 35 years, which places you at more risk of conceiving a child with chromosome condition.
  • Your partner or you suffer from a chromosome condition, or either of you has a child with the condition (e.g. down syndrome)
  • You or your partner stands a higher risk of passing a genetic condition to the child (e.g. cystic finriosis)

It is recommended that couples opt for genetic testing before pregnancy as this helps them to understand what could happen to the baby. It is the most accurate solution as it allows them to pursue protective measures. It impacts their decision making to ensure they don’t conceive a child with genetic anomalies.

It’s important to prioritize genetic testing as a way to understand the health of a baby. Before birth, parents need to visit their doctor for screening to find out if there is a condition the baby might have picked from both or either of the parents. Do both diagnostic and prenatal genetic tests to ensure you understand the health of your baby.
