This test is a three- part screening process which includes an assessment of: Combined First Trimester Screening assesses your baby’s risk for chromosomal abnormalities particularly Down Syndrome (Trisomy 21) and two other more common chromosome abnormalities; Edwards Syndrome (Trisomy 18) and Patau’s Syndrome (Trisomy 13).
It is possible that some non-chromosomal abnormalities such as neural tube defects, heart and structural abnormalities can also be detected at this stage of pregnancy.
As part of the First Trimester Screen, a risk factor rating will be determined for a mother’s likelihood of developing the early- onset type of pre-eclampsia.
Assessment will be made of the following: Preventative medication is offered to women whose risk comes back as higher than 1%.
Pre-eclampsia is a condition unique to pregnancy that is associated with the development of high blood pressure after 20 weeks gestation.
The abdominal probe is gently moved around the abdomen to obtain ultrasound images.
Commonly in very early pregnancy, even clearer images of the pregnancy can be obtained using an ultrasound probe placed in the vagina (called a transvaginal ultrasound).
Pre-eclampsia can affect the health of a mother, placental function and the growth and wellbeing of the baby in utero.
If it occurs early in the second half of the pregnancy (before 34 weeks), it may also result in premature delivery.
