When a woman is pregnant, there are a series of tests that she will go through to ensure that both she and the baby are healthy. The first test usually performed by the doctor is a urine or blood test to confirm that the woman is indeed pregnant.
After confirmation, most women typically undergo a second-level pregnancy test, commonly called the prenatal screening test.
What is the Prenatal Screening Test?
The prenatal screening test is done in the first or second trimester of pregnancy. This test assesses the likelihood of chromosomal abnormalities in the developing fetus, such as Down syndrome.
The screening test involves a blood test and an ultrasound examination. During the blood test, the healthcare professional measures the levels of certain substances in the blood.
The health care provider also measures the thickness of the nuchal translucency, which is the accumulation of fluid at the back of the baby’s neck. This measurement is captured through ultrasound. In combination, the blood test and nuchal translucency measurement will help the doctor to determine the likelihood of chromosomal abnormalities present in the fetus.
Why is the Prenatal Screening Test Crucial?
The prenatal screening test is essential to detect chromosomal abnormalities present in the fetus. Early detection can help the mother and her healthcare team to prepare if the baby is born with a complication.
It might be beneficial to the health care provider to recheck when they find unusual measurements or levels in the prenatal screening test. When this test is done earlier in the pregnancy, there is time to prepare for the proper care of the baby to avoid complications.
The prenatal screening test is a non-invasive procedure that poses no risk to the mother or the baby. For this reason, it is recommended as a routine and is performed on almost all pregnant women.
The test gives the mother a chance to understand what is happening in her pregnancy and can help her emotionally prepare for the arrival of her baby.
What Happens If Abnormalities are Detected?
If chromosomal abnormalities are detected in the fetus, the doctor will discuss the results of the prenatal screening test with the mother. The discussion will outline the possible ramifications of the baby being born with chromosomal abnormalities.
The doctor will also suggest further diagnostic tests to confirm the results of the prenatal screening test.
Further diagnostic tests may include Chorionic villus sampling (CVS) or Amniocentesis. During CVS, the healthcare provider removes a small sample of the placenta. During Amniocentesis, a sample of amniotic fluid is removed for analysis.
Both of these tests are invasive and pose a minor risk to the mother and the baby. However, these tests are highly accurate and can confirm or deny the results of the prenatal screening test.
The Benefits of Early Detection
If chromosomal abnormalities are detected in the prenatal screening test or through further diagnosis, early detection can help the mother prepare emotionally and mentally for her child’s arrival.
She can learn about the condition and seek support from the healthcare provider and support groups. Scheduling a C-section in advance can avoid further complications during birth.
When chromosomal abnormalities are suspected, further tests can be recommended to ensure that the mother can receive the proper medical care to support her health and the baby’s needs during and after birth.
Early detection can help treatment of certain medical conditions and help the baby to live a healthy and happy life.
In Conclusion
The prenatal screening test is an essential part of prenatal care for women who are pregnant. This non-invasive test that poses no risk to the mother or the baby helps doctors determine the likelihood of chromosomal abnormalities present in the fetus.
While abnormal results in the prenatal screening test can be concerning, early detection through this test and further diagnostic tests, can help provide proper medical care for the mother and the baby’s long-term health and wellness.
