You are at the end of a very special period in your life, aren't you? When you hear that your baby is about to be born, there is a feeling of excitement and a little bit of anxiety. At this time, we are all very concerned about the health of you and your little one in the womb. So, today I am here to talk about some of the tests that are done during this third trimester, that is, the last three months. These can provide you and your baby with very valuable information.
Why are these tests so important?
Think about how important it is to know the pros and cons of a test when your doctor or nurse tells you to do something. Many mothers say that these tests give them a lot of peace of mind and help them prepare for the arrival of their baby. But remember, you have the right to decide whether or not to have these tests.
You may remember that when you found out you were pregnant, the first day you went to see the doctor, they did a full physical exam, a urine test, and a blood test. At that time, your:
- Blood type and `Rh factor` (if your blood is `Rh negative` and your husband's blood is `Rh positive`, `antibodies` can form that can affect the baby. To prevent this, a medication is given at around 28 weeks.)
- Is there a lack of blood, that is , anemia?
- Are there diseases like `Hepatitis B` , `Syphilis` , and `HIV` ?
- Are you immune to German measles (Rubella) and chickenpox (Varicella) ?
- Genetic diseases like Cystic Fibrosis and Spinal Muscular Atrophy are also now being tested for, even if no one in the family has had these before.
After that, every time you see your doctor, they will check your urine, weigh you, and check your blood pressure. These can help detect early signs of things like gestational diabetes and preeclampsia, a dangerous condition that causes high blood pressure.
Now let's talk about the special tests that are done in these last few months, that is, in the third trimester. Your doctor will decide whether you need these tests based on factors such as your age, health status, and family medical history.
What are the main tests performed in the third trimester?
Okay, so let's see what major tests you have to do during this time.
1. Ultrasound Scan
You've probably heard of this one. An ultrasound is a painless, very safe test. It uses sound waves to create an image of your baby, looking at things like their shape, position, and where they're located in the uterus. An ultrasound is done in the third trimester to check the placenta . Sometimes, it's also done as part of a test called a Biophysical Profile (BPP) to check if the baby is getting enough oxygen. For women with high-risk pregnancies, multiple ultrasound scans may be done at this time.
Imagine how exciting it would be to see your little one's movements in the womb! This gives doctors very important information about the baby's development.
2. Glucose Screening
This test checks to see if you have ``Gestational Diabetes`` (diabetes during pregnancy). This is a temporary form of diabetes that some mothers develop only during pregnancy. However, if it is not recognized and treated properly, it can cause health problems for the baby.
During this test, you will be given a sugary drink. Then, about an hour later, your blood will be drawn to check your glucose level. This sugary drink may be uncomfortable for some people, but it is very important for your baby.
3. Group B Strep Test
This test is done between 35 and 37 weeks of your pregnancy. It checks whether you have a bacterial infection called `Group B Streptococcus (GBS) .` GBS bacteria are naturally present in the vagina of many women, but it can cause serious infections in newborn babies.
This test involves taking a swab sample from either the vagina or the anus. If this test is ``positive``, meaning there is an infection, you should go to the hospital as soon as you start giving birth. Then the doctors will start giving you intravenous (IV) antibiotics to protect your baby from infection. Don't worry, this will provide great protection for your baby.
4. Nonstress Test (Nonstress Test - NST)
A `Nonstress Test (NST)` is usually done when the doctor wants to know more about the baby's health. This is especially true in high-risk pregnancies or when the baby's due date is past.
This test checks whether the baby is responding normally to stimulation and whether the baby is getting enough oxygen. Think of it like checking if the baby is okay inside. Even if the baby is not responding, it doesn't always mean that the baby is in danger, but more tests may be needed.
5. Contraction Stress Test
This test involves injecting the uterus with a drug called Pitocin (a synthetic form of the hormone oxytocin , which is released during labor). This test measures how the baby's heart rate responds to the contractions. Your doctor may recommend this test if a previous test suggests a problem. The goal is to check whether the baby's heart rate is stable during uterine contractions.
Remember, the decision is yours!
Even though you are aware of all these tests, the most important thing is that these tests are only "suggested" things for you to do. You have the full right to decide whether or not to do them.
To decide which tests are right for you, talk to your doctor. Find out why you're having this test, what the benefits are, what the risks are, and what the results can and cannot tell you.
Finally, remember this (Take-Home Message)
You and your unborn baby need the best care possible during this final, most precious period of your pregnancy. These tests are just a way to help you do that.
- There's a reason for every test: A doctor doesn't just suggest a test. He or she thinks about the benefits it will bring to you and your baby.
- Don't be afraid to ask questions: If there is anything you don't understand or have any doubts, be sure to ask your doctor.
- Make informed decisions: Know the pros and cons of each test and make a decision that is in line with your own feelings.
- Think positively: All of this is done to welcome a healthy, happy baby into the world.
I sincerely hope that you and your family will spend this special time happily and healthily!
