The goal of
every pregnant woman and her doctor is the birth of a healthy
baby. 2 to 3% of babies are born with some type of birth
(congenital) defect. The First Trimester Pregnancy Screen (FTPS)
gives important information about your baby, including risks
of birth defects or possible pregnancy complications.
What's First Trimester
Pregnancy Screen?
The FTPS combines a high
resolution ultrasound scan with maternal blood screening
during the late first trimester i.e. 11 to 14 weeks of
pregnancy. Nuchal translucency measurements are made i.e. the
amount of fluid at the back of the neck. NT thickness serves
as an indicator of chromosomal disorder. In addition, the
mother's blood sample is analysed for 2 chemicals, free beta
human chorionic gonadotrophin (beta-hCG) and pregnancy
associated plasma protein- A (PAPP-A).
The ultrasound and blood test
results are combined to estimate the risks of Down Syndrome.
FTPS detects 90% of Down Syndrome as well as some other birth
defects. It is a non-invasive test and is therefore safe for
both mother and fetus.
What is the risk of Down
Syndrome?
Down Syndrome is the
commonest chromosomal abnormality and is associated with
reduced IQ, developmental delay and other congenital defects.
The risk increases with maternal age and is tabulated below.
| Mother's Age weeks |
Risk of Down Syndrome @
12 weeks |
| 20 yrs |
1 in 1068 |
| 25 yrs |
1 in 946 |
| 30 yrs |
1 in 626 |
| 35 yrs |
1 in 249 |
| 40 yrs |
1 in 68 |
What does FTPS show?
The measurements taken
during the FTPS gives a risk score which indicates whether the
risk is higher or lower than that expected for a particular
age group. E.g., a risk score of 1 in 800 for a 35 year old
expectant mother means that she is not at increased risk of a
Down Syndrome baby in spite of her age.
FTPS is recommended
because it:
-
Gives important information
about your baby.
-
Detects more birth defects than 2nd trimester
screening.
-
Helps identify over 90% of Down Syndrome and other birth
anomalies including heart defects.
-
Reduces unnecessary anxiety, saves time and cost.
-
It is approved by the Royal College of Obstetrics &
Gynaecology as the test for the first trimester screening.
