Pregnancy check-ups

When you go for appointments with your doctor, he will first check your weight and blood pressure. Often, the doctor might ask you to provide a urine sample to check if you are suffering from any infection. When the doctor feels the presence of protein in the urine, he will treat you against pre-eclampsia.
Further, the doctor will also take measurements of your belly to ensure that the baby is growing. For dilation purposes, the doctor may check the cervix area. To keep you away from anaemia the doctor will ask you to undergo a blood test to see the condition of the red blood cells.

List of health tests during the third trimester

Sometimes things don’t work according to your plan. Even if you want a healthy pregnancy, it can create some risk factors. To check if you and your baby are at a risk, the doctor asks you to undergo a couple of tests. We have given below a list of foetal tests that can determine the condition of the foetus inside your womb.

  • Amniocentesis

When the doctor feels that the baby has been infected by a bacterial infection known as chorioamnionitis, he might ask you to undergo an amniocentesis test. Another reason for conducting this test is to check foetal anaemia. Normally the doctor prescribes this test in the second trimester to check if there are chromosomal issues in the baby. Another condition for which the doctor asks you to undergo this amniocentesis test is to find out if the baby has a foetal lung infection.

To conduct the process of amniocentesis the doctor will first put inside your abdomen a thin and long needle through the uterus. The purpose of this needle is to get some amniotic fluid as a sample. Next, the doctor will take you for an ultrasound to check the exact position of the baby so that the needle does not hurt them. During amniocentesis, if the doctor is not careful it can lead to premature delivery or a miscarriage.

  • The nonstress test

The purpose of the non-stress test is to check the heart rate of the baby, especially while their moving in the amniotic fluid. The doctor asks you to undergo a non-stress test when they feel that the baby is not moving. Another condition to conduct a non-stress test is when you have gone past your due delivery date. Besides the non-stress test measures the healthiness of the placenta.

To conduct this test, the doctor uses a fetal monitor placed on your baby bump and checks the heart rate of the baby for 20 to 30 minutes. If you have a disc in your pregnancy your doctor will ask you to conduct the non-stress test at least once a week or at the beginning of your 30th week. When the baby inside your home is sleeping the heart rate is automatically slow. In that case, the doctor will try to wake the baby inside you to monitor the correct heart rate.

  • Contraction stress test or oxytocin challenge

The purpose of the contraction stress test is to measure the foetal heart rate with some more stress. Indeed, there is not much difference between the non-stress test and the contraction stress test. While the former does not use any stress, the latter uses a little bit of stress to check the heartbeat of the baby.

To stimulate the baby inside and induce mild contractions, the doctor may sometimes use oxytocin. It is because the goal of this contractions stress test is to find out the response of the baby’s heartbeat to the contractions. When everything is normal the doctor will find a stable heart rate even if there is a restriction of blood flow into the placenta. In case of an unstable heart rate, the doctor will give you an idea as to the reaction of the baby after its delivery. As a result, both you and the doctor discuss the time and the method of delivery.


So, if you are worried about the health of your baby, you should undergo all the tests that the doctor advises you to do, especially in your third trimester. In any case, if the doctor notices any complications, he will guide you in the best possible way. Or, if you find anything abnormal, do not as hesitate to share it with your doctor and take the necessary help.
