Why Is Prenatal Screening Important?


Pregnancy is a very exciting time for anybody who is waiting to be a parent. But today sadly, we have exposed ourselves to so much chemicals and harmful agents that our health is nowhere near the great level of health that was present during the times of our grandparents. This is why most couples opt for prenatal tests and screening because that gives them the chance to understand any health issues that they might have and that they could possibly pass on to their child through genetics.

Screening Tests

One of the core varieties of prenatal testing is screening. Prenatal screening tests are able to pinpoint for youif your baby may or may not have a risk of different birth defects, and these could include the majority ofgenetic problems. The testsmay consist of blood tests, along with a particular variety of ultrasound tests as well as prenatal “cell-free DNA screening”, as well as nips test.

These tests will be available to you usually within the first or the second trimester and you also have to know that these will not be able to offer you a confirmative diagnosis. If there are results that indicate some kind of elevated risk of a genetic disorder, your medical care expert will ask you to go through a diagnostic test to make sure of this this without doubt.

Diagnostic Testing

This brings us to the second type of main prenatal testing known as diagnostic testing. If a specificscreening could indicate some kind of risk factor or hint at a possible health issue, that could be passed on to your baby through genetics, you may need to undergo a somewhat invasive diagnostic test depending upon the nature of the issue that is suspected. Diagnostic testing is also the only correct way in which you can confirm a diagnosis and is therefore crucial. However, you should also know that some tests like chronic villus sampling and amniocentesis may carry a small chance of miscarriage.

What Is A First Trimester Or 3 Months Screening Test?

During your first trimester or the first three months, your obstetrician or doctorcarries out an ultrasound, blood test or bothtake a measurement of the dimensions of that clear space known as the nuchal translucency that is located behind the baby’s neck. In some health conditions like Down Syndrome for instance, this is unusually large which could give doctors an indication.

What Is A Second Trimester Screening Test?

 During your second trimester or the 3 – 6-month period, your doctor or your obstetrician will carry outa second blood test which is known as the quad screen. This examination will effectively measure the levels of the 4 types of substances in your blood and the resultsof this test could point in the direction of your risk of conceiving a baby who may have some chromosomal conditions, for example, Down syndrome.

This can also be helpful in identifying neural tube defects like critical issues of the spinal cord or the brain. It is important to remember that you should comply with what your doctor tells you and trust them. Getting these tests done will help you during your pregnancy. Don’t be afraid to get help that could help your baby too.
