What’s Happening at The 20 Weeks Ultrasound

During an ultrasound appointment, the ultrasound tech thoroughly examines the baby's body. They scan the brain, spine, face, abdomen, and limbs, examining each part for proper development. But it doesn't stop there - they also measure everything to ensure the baby is growing at the right pace for their gestational age. These measurements are plotted against nomograms, giving an overall picture of the fetus's growth. The process may sound intricate, but it's all to ensure the little one is healthy and thriving.

During a prenatal scan, your uterus and placenta are studied to ensure the well-being of both you and your growing baby. The uterus is examined to identify any possible problems that could impact the pregnancy, such as a uterine septum. Uterine fibroids, which are non-cancerous masses in the uterus, can also be detected during this examination. The placenta is thoroughly evaluated to assess where it has attached to the uterus. This determines whether it is covering the cervix or located in an area where you had a previous cesarean section scar. Additionally, the location where the umbilical cord is attached to the placenta is checked. This scan gives doctors helpful information to help them prepare for your delivery and ensure a smooth pregnancy.

Your healthcare provider may measure the levels of amniotic fluid in your uterus. This fluid is crucial for the development and protection of your growing fetus. Amniotic fluid levels are influenced by fetal functions such as swallowing, urine production, and placental function. High or low levels of amniotic fluid may indicate potential issues that could affect fetal health, such as placental dysfunction or genitourinary problems. It is important to note that these problems are usually identified later in pregnancy, around the third trimester. Your provider will monitor your amniotic fluid levels to ensure your baby is healthy and developing correctly.

Finding Out The Gender

Curious about the gender of your baby? Well, now you don't have to wait any longer. With today's advanced technology, you can simply get a scan and find out whether you're having a little boy or a girl. However, if you want to keep it a secret, let your tech know beforehand. Don't worry about preparing much for the scan; just show up and be ready to spend some time. Depending on the baby's position, the scan can take about 30 to 45 minutes or even longer if you have to play the waiting game for the perfect pose.

Additional 20 Weeks Tests

Around 16 to 20 weeks into your pregnancy, you'll likely be offered additional screening tests to check your baby’s health. It's essential to understand the difference between a screening test and a diagnostic test. A screening test is designed to assess the likelihood that your baby may have a disorder based on blood samples and ultrasounds. Meanwhile, a diagnostic test confirms whether your baby has the condition and typically involves extracting cells from the placenta or fetus. These tests can be beneficial for detecting potential issues early on during your pregnancy to help you make informed decisions.

During pregnancy, most women are offered screening tests to assess the risk of potential disorders for their babies. However, it's essential to understand that these tests aren't always accurate. A positive result doesn't necessarily mean something wrong with your baby; it simply means they may be at a higher risk than the general population. Similarly, a negative result doesn't guarantee that there are no problems present. Diagnostic tests are typically reserved for those in high-risk groups or when a particular concern requires further examination. Ultimately, the decision to undergo any type of prenatal testing is one that should be made in consultation with a healthcare professional.

Genetic Carrier Screens

Did you know that you can carry a disease even if you do not have it? This is where genetic carrier screens come into play. Certain ethnicities are more likely to carry specific genetic conditions, such as Tay-Sachs for Ashkenazi Jews and sickle cell for African Americans. As a result, genetic carrier screens are often given based on a person's ethnicity. Understanding the potential risks can help you and your healthcare provider take proactive measures to manage your health.

Quad Screen

The quad screen involves the measurement of four substances in your blood, which is used to determine your baby's risk of having a neural tube defect, Down syndrome, or another genetic condition. This test is done in the second trimester and is another way to screen for Trisomy 21. It's an actual test that allows expectant mothers to receive care beyond 14 weeks when nuchal translucency screening is no longer an option. If you're due for this test, it's essential not to panic because the results are only indicators, and a definite diagnosis may require further diagnostic tests.
