Types of Genetic Screening
There are different types of screening tests conducted for different reasons because they play a vital role in determining the risk that’s been associated with the diseases that the body has been diagnosed with. Let’s explore them one by one:
Carrier Testing
The most common and widely used testing where if anyone from a family or individual has a genetic problem, you need to do a genetic test before planning for a child. It will help you identify the specific disease that you carry and whether you or your partner are carriers of the same or not.
Prenatal Screening and Diagnostic Screening
Prenatal testing refers to screening conducted during pregnancy to make sure that there are no potential genetic disorders, chromosomal abnormalities, and other conditions that may affect the baby.
It is divided into two categories: Screening tests and diagnostic tests.
Screening tests help to assess the risk of certain conditions in the fetus such as to evaluate the baby’s growth and check physical abnormalities.
On the other hand, the latter provides a more conclusive diagnosis because one of its tests includes the removal of fluid around the baby which involves a higher risk of complications.
These tests are performed when an individual exhibits certain symptoms, has abnormal screening tests, or needs to go through further tests that will have various methods, including laboratory tests, imaging scans, biopsies, genetic testing, or specialized procedures.
It helps the couple make informed decisions about pregnancy and make them prepare for potential health concerns.
Newborn Screening
Immediately after birth, there might be a few disorders in the newborn. It involves collecting a blood sample and analyzing the specific abnormalities associated with various conditions.
By detecting this at an early stage, it allows for timely intervention and treatment, ultimately minimizing potential health conditions. This will help newborn children have the best chances at a healthy start in life.
