14-21 Weeks' Pregnant
In your second trimester of pregnancy, you may be able to choose from the following tests:
| Second Trimester Screening
You can have OHIP-funded Second Trimester Screening (STS) in the second trimester of pregnancy. There is no risk to the pregnancy because it is done through blood work. This testing can tell you the chance for having a baby with trisomy 21 (Down syndrome) or trisomy 18 (Edwards syndrome).
| Non-Invasive Prenatal Testing
Non-invasive Prenatal Testing (NIPT) is the most accurate prenatal genetic screening test and may be OHIP-funded or private-pay depending on your situation. There is no risk to the pregnancy because it is done through blood work. NIPT can tell you the chance for having a baby with trisomy 21 (Down syndrome), trisomy 18 (Edwards syndrome) and other chromosome differences. You can have NIPT from the time you are 9 or 10 weeks pregnant until the end of the pregnancy.
| 18-22 week ultrasound
You can have the 18-22 week ultrasound no matter what prenatal genetic screening choice you make. This ultrasound gives you information about the health of the baby and other aspects of the pregnancy. It is sometimes called the second trimester scan or the detailed anatomy scan.
