13 Weeks - First trimester screening (T1 Scan)

First trimester screening is a prenatal test that offers early information about a baby's risk of certain chromosomal conditions like Trisomy 21 (Down syndrome) and Trisomy 18 (Edwards syndrome).

Typically, first trimester screening is done between weeks 11 and 13 of pregnancy. 

If results show that your risk level is moderate or high, you might choose to follow first trimester screening with another test that's more definitive.

As the nuchal translucency measurement increases, so does the risk of Down syndrome and other chromosomal abnormalities. The accuracy rate of the nuchal translucency screening is just 70-75%.

I have done my first trimester screening at week 13 in Metro IVF, Puchong branch. The result came out shows everything is fine. My baby's average heart beat rate is 154bpm, baby 's size is 6.89cm and the size of the clear space in the tissue at the back of baby's neck (nuchal translucency measurement) is 0.90mm.
