Prenatal Care

Prenatal care is vital for a healthy pregnancy. It involves regular check-ups with your health care provider, monitoring your baby’s development, and education and support on how to have a healthy pregnancy.

Your first prenatal visit will be around 8 weeks after your last menstrual period. Your provider will likely do a physical exam and order some tests, including a blood test to check for anemia and a urine test to check for protein and sugar. You will also have a dating ultrasound to confirm your due date.

During each subsequent visit, your provider will monitor your weight, blood pressure, and urine. They will also feel your abdomen to check the baby’s size and position and listen to the baby’s heartbeat. You will continue to have ultrasounds throughout your pregnancy to assess the baby’s growth.

Blood Tests

During pregnancy, approx 50% of a woman’s blood volume increases. This increase in blood volume is necessary to support the developing baby as well as the placenta and uterus. To make sure that the mother and baby are healthy, various blood tests are done throughout pregnancy.

Pregnancy is an exciting time, but it can also be a time of worry and anxiety. With so much to think about, it’s natural to wonder what medical tests are done during pregnancy.

The good news is that there are only a few routine tests that are done during pregnancy. These tests are important in helping to ensure the health of both you and your baby.

One of the most important tests is ultrasound. This test is usually done around 20 weeks into the pregnancy. It allows the doctor to get a clear picture of the baby’s development and to check for any potential problems. Punjab’s best diagnostic service provider

Maternal Blood Test

Another common test is the maternal blood test. This test is usually done around 16 weeks into the pregnancy. It checks for certain conditions that could affect the health of either you or your baby.

Glucose Tolerance Test

Most pregnant women will have a glucose tolerance test around 28 weeks into the pregnancy. This test helps to screen for gestational diabetes, which can be a concern for some women during pregnancy.

While these are the most common tests that are done during pregnancy, your doctor may recommend other tests based on your individual medical history and/or concerns. So if you have any questions or concerns about what tests you may need during your pregnancy, be sure to talk to your doctor. 

Screening Tests

There are a variety of screening tests that are done during pregnancy in order to assess the health of both the mother and the developing baby. These tests can help to identify any potential complications or risks and allow for early intervention if necessary. 

Some of the most common screening tests include Ultrasound, Blood tests, and urine tests.

Biophysical Profile

A biophysical profile (BPP) is a type of screening test that assesses fetal well-being. It is typically done during the third trimester of pregnancy, around week 32.

The test consists of two parts: an ultrasound examination and a non-stress test (NST). The ultrasound component looks at the fetus’ breathing movements, movement of the limbs, body tone, and amniotic fluid volume. The NST monitors the fetal heart rate in response to movement.

A BPP is considered normal if all four parameters are within normal limits. If any of the parameters are abnormal, further testing may be needed to assess fetal well-being.


Amniocentesis is a medical procedure used to diagnose genetic abnormalities in a developing baby. It involves inserting a needle into the uterus and withdrawing a small amount of amniotic fluid.

The amniotic fluid surrounds the baby in the womb and contains cells that are a part of the baby’s development. By testing these cells, doctors can check for certain birth defects, such as Down syndrome or spinal cord defects.

Amniocentesis is usually done between the 15th and 20th weeks of pregnancy, but it can be done earlier or later in pregnancy if needed. The procedure is generally safe, but there is a small risk of miscarriage.

Chorionic Villus Sampling

Chorionic villus sampling (CVS) is a prenatal test that is performed to detect any chromosomal abnormalities in the developing baby.

During CVS, a small amount of tissue is taken from the placenta, which contains the baby’s DNA. This sample is then analyzed for any genetic abnormalities. CVS is considered to be a very accurate test, with a detection rate of over 99% for certain conditions such as Down syndrome.


Pregnancy is an exciting and sometimes daunting time, but with the right preparation and knowledge, you can feel more confident throughout the entire process. Being aware of what medical tests are done during pregnancy will help you make informed decisions about your prenatal care and ensure that both mother and baby stay healthy. Whether it’s a routine check-up or something more specialized, having a clear understanding of all available tests can help you create a customized plan for your pregnancy journey.
