Why Get Tested?
To confirm and monitor pregnancy or to diagnose trophoblastic disease or germ cell tumours
When to Get Tested?
As early as 10 days after a missed menstrual period (some methods can detect hCG even earlier, at one week after conception) or if a doctor thinks that your symptoms suggest ectopic pregnancy, a failing pregnancy, trophoblastic disease or germ cell tumours
Human chorionic gonadotrophin (hCG) is also tested as part of the prenatal screening program for Down’s syndrome.
A urine sample collected first thing in the morning or a blood sample taken from a vein in the arm
Test Preparation Needed?
None needed; however, do not drink large amounts of fluid before collecting a urine sample for a pregnancy test because overly dilute urine may result in a false negative test result.
