Treatments and tests

Tests for pregnant women

During your first trimester (the first 3 months of your pregnancy) you may be offered the following tests to check if you have any infections or health conditions:

  • full blood count
  • glucose challenges for gestational diabetes
  • blood group and antibodies
  • midstream urine
  • random blood glucose
  • syphilis
  • rubella 
  • hepatitis B and C
  • HIV antibodies 
  • chlamydia screening
  • sickle cell and Thalassaemia (haemoglobinopathy) screening for at risk women (specifically those with a  Mediterranean, Middle Eastern, African, Asian, Pacific Islander, South American, or New Zealand Maori background).

A number of these tests will be performed from one blood sample.

You will also have an ultrasound to:

  • estimate your due date (you can also estimate it based on your last menstrual period by adding 40 weeks (280 days) to the first day of your last menstrual cycle)
  • check the number of babies and their development.

It is best to have these tests as early as possible in your pregnancy.

Your doctor will explain the meaning of your test results.
