Blood tests are an essential part of prenatal care. They can help your doctor track your health and the health of your baby, and screen for potential problems.
How Many Blood Tests Are Taken During Pregnancy?
The number of blood tests you will need during pregnancy will vary depending on your individual health and risk factors. However, most women can expect to have at least 9 blood tests during their pregnancy. The American College of Obstetricians and Gynecologists (ACOG) recommends that all pregnant women have the following blood tests:
First Trimester
- Blood type and Rh factor: This test determines your blood type and Rh factor. If you are Rh-negative, you will need to receive a RhIg injection to prevent Rh incompatibility.
- Complete blood count (CBC): This test measures the number of red blood cells, white blood cells, and platelets in your blood. It can help diagnose anemia, infection, and other conditions.
- Hepatitis B surface antigen: This test checks for hepatitis B, a viral infection that can damage the liver.
- HIV: This test checks for HIV, the virus that causes AIDS.
-
Syphilis: This test checks for syphilis, a bacterial infection that can cause serious health problems for you and your baby.
Second Trimester -
Glucose screening test: This test checks for gestational diabetes, a type of diabetes that can develop during pregnancy.
- Multiple marker screen: This test screens for Down syndrome, trisomy 18, and other chromosomal abnormalities.
- AFP: This test measures the level of alpha-fetoprotein (AFP) in your blood. High levels of AFP can indicate neural tube defects, such as spina bifida.
Third Trimester
- Group B strep (GBS): This test checks for GBS, a bacterium that can cause serious infection in newborns.
What Do the Results Mean?
The results of your blood tests will be interpreted by your doctor. Your doctor will let you know if any of your results are abnormal and will recommend further testing or treatment if necessary.
Benefits of Blood Tests During Pregnancy
Blood tests during pregnancy can provide valuable information about your health and the health of your baby. They can help your doctor:

Risks of Blood Tests During Pregnancy
Blood tests are generally safe and have few risks. However, there are some potential risks, such as:
- Pain or bruising at the injection site: This is the most common side effect of blood tests.
- Infection: In rare cases, blood tests can cause infection.
- Fainting: Some people may feel faint during or after a blood test.
How to Prepare for a Blood Test
Here are some tips on how to prepare for a blood test during pregnancy:
- Fast for 8-12 hours before the test: This is required for the glucose screening test.
- Drink plenty of fluids before the test: This will help your veins to be more visible and make it easier to draw blood.
- Wear comfortable clothing: You will need to remove your shirt or blouse for the blood draw.
- Bring a book or magazine to read: This will help you relax during the test.
