What We Screen For In Ontario

Prenatal screening can tell you the chance for having a baby with certain chromosome differences. The conditions formally screened for in Ontario are: 

• Trisomy 21 (Down syndrome)
• Trisomy 18 (Edwards syndrome)

A screening test called Non-Invasive Prenatal Testing (NIPT) might also tell you the chance for having a baby with other chromosome differences,  including trisomy 13 (Patau syndrome) and sex chromosome differences. NIPT is OHIP-funded or paid for out-of-pocket, depending on the situation.
