Pregnancy test

Pregnancy test A pregnancy test is used to determine if a woman is pregnant. It is usually performed when a health professional or a woman suspects she is pregnant, or before using clinical services that may interfere with a pregnancy. This is done by analysing a sample of urine or blood for the hormone human chorionic gonadotropin (hCG).

For more information, see Pregnancy Test.

Obstetric ultrasound

Obstetric ultrasound Some women will realise they are pregnant if they experience symptoms such as frequent urination, nausea (morning sickness), and a late period. However, pregnancy can be confirmed using a urine test available at pharmacies. An obstetric ultrasound may also be used to diagnose pregnancy and to estimate a due date.
