What are antenatal tests?
Antenatal tests help make sure that you and your baby are healthy throughout your pregnancy. Antenatal tests are an important part of your pregnancy care.
Several tests, including blood tests, urine tests and ultrasound scans are used to check various aspects of your and your baby’s health.
Some tests are recommended for everyone, while others are only offered if there is a greater chance that you or your baby have a particular condition.
At your first antenatal visit, your doctor or midwife will explain which antenatal tests are recommended. They will give you a list of when you should have them.
Of course, things might change during pregnancy, so you need to be flexible about what appointments and tests you will have.
What is a screening test?
Some antenatal tests are screening tests. This means that they are designed to estimate the chance of you or your baby having a particular condition.
What is a diagnostic test?
A diagnostic test can tell you for certain whether your baby has a condition. If you receive a high-risk result on a screening test, you might be referred for a diagnostic test.

Why do I need tests during pregnancy?
Antenatal tests are an important way to check your own and your baby’s health and wellbeing throughout your pregnancy. Antenatal tests can help to:
- pick up medical problems early so they can be treated
- identify any genetic conditions affecting your baby, so you can decide what to do next
- check that your baby is growing and developing
It’s important to try to do the tests at the recommended time to make sure you get the most accurate information. The test results are used to help you and your healthcare team make any necessary decisions about your pregnancy.
Ask your doctor or midwife if you’re not sure when you need to have a particular test, or why it is recommended for you.

Do I have to have the routine antenatal tests?
During pregnancy, you and your doctor and midwife can decide together which tests you will have.
You will be given information about each test so you can make an informed decision.
You can choose whether to have antenatal tests. You may decide to have all the tests recommended or only a few.
It’s a good idea to think about the possible results of antenatal testing, and how you might feel when you get the results.
Many people find it helpful to ask questions and discuss their options with their doctor or midwife. You can talk to your partner, close family and friends to help you make choices that are right for you.
Be careful about following advice from the internet or social media since it may not be accurate.
Your doctor or midwife can answer your questions and give you accurate information and advice about your situation.
Questions for your doctor
Here are some questions you might want to ask your midwife or doctor:
- Why are you offering me this test?
- What does the procedure involve?
- Do I need to do anything on the day?
- When will I get the results?
- Who will contact me to give me the results?
- Do I need to do anything to care for myself after the procedure?
More questions to ask your doctor about tests and scans.
Who will do the tests?
Your doctor or midwife will refer you for any antenatal tests that are recommended.
Blood tests
Blood tests are usually done at a pathology collection centre or hospital by a trained pathology collector.
Ultrasound scans
Ultrasound scans are usually performed by a specially trained technician called a sonographer. They can also be done by doctors, midwives or other health workers. Scans may be performed in a radiology clinic or a hospital.
Specialist tests
Procedures such as chorionic villus sampling (CVS) and amniocentesis are done by a specialist doctor in a clinic or hospital.

What do antenatal tests cost?
Medicare covers at least some of the cost of routine antenatal tests. You can get some money back or be bulk billed for many ultrasounds and blood tests.
However, not all antenatal tests are covered by Medicare. You may need to pay an out-of-pocket cost, depending on the test and where you get it done. Speak to your doctor if you are worried about the cost of antenatal tests.
It’s a good idea to check about the fees when you book your appointments.
What happens when I get the results?
Your doctor, obstetrician or midwife can answer your questions and give you more information about antenatal tests. They can also discuss the meaning of your test results.
They may also suggest talking to a genetic counsellor, who can guide you through the implications of your results, any decisions you may need to make and the relevant support available.
The best way to contact a genetic counsellor is to ask your doctor. They can refer you to a genetic counselling service.
The Human Genetics Society of Australasia also has a Find a Genetic Counsellor service. It can help you find a registered counsellor in your area.
