I Have NOT Had Prenatal Genetic Screening in this Pregnancy

If you are between 14 weeks and 20 weeks 6 days gestation, you may have the choice between Maternal Serum Screening (MSS) and Non-Invasive Prenatal Testing (NIPT). 

Option 1: Maternal Serum Screening (MSS)

• Involves a blood test, and can only be done for individuals that are expecting one baby.
• You can choose to have MSS if you missed the window for an earlier test, called enhanced First Trimester Screening (eFTS). You do not need to have MSS if you already had eFTS, as these two tests screen for the same conditions. 

Option 2: Non-Invasive Prenatal Testing (NIPT)

• Involves a blood test, and is the most accurate of the available screening tests.
• OHIP-funded in certain circumstances (e.g. when there is an increased chance for the baby to have trisomy 21 or trisomy 18).  You can choose to pay for NIPT if the test is not OHIP-funded in your situation.

I Had a Prenatal Genetic Screening Test (eFTS or MSS)

• If you had a traditional screening test (usually enhanced First Trimester Screening or Maternal Serum Screening), you would receive either a screen positive (high risk) or screen negative (low risk) result.  
• Many individuals will not follow up with another prenatal genetic screening test in their pregnancy. However, some will consider having Non-Invasive Prenatal Testing (NIPT). NIPT is a highly effective screen, consisting of a blood test. NIPT is OHIP-funded in certain situations. For example, a screen positive (high risk) result from a traditional screening test, or concerns on an ultrasound may prompt the offer of OHIP-funded NIPT, among other options.
