What Is First Trimester Screening?
The First Trimester Screening is a vital, non-invasive test performed between 12 and 14 weeks of pregnancy. It combines:
- Nuchal Translucency (NT) Scan – A specialized ultrasound
- Biochemistry Test (Dual Marker) – A blood test measuring specific hormones
Together, these help assess the risk of chromosomal abnormalities in the baby, including Down syndrome (Trisomy 21), Edwards syndrome (Trisomy 18), and Patau syndrome (Trisomy 13).
What Does the NT Scan Measure?
The NT scan evaluates the fluid thickness at the back of the baby’s neck. Increased fluid levels can be a soft marker for certain genetic conditions or heart problems. It also includes:
- Crown-Rump Length (CRL) – Confirms gestational age
- Nasal bone visibility – Another key marker
- Fetal heartbeat and movement
What Is the Dual Marker Test?
The dual marker test measures two important substances in the mother’s blood:
- Free Beta-hCG
- PAPP-A (Pregnancy-Associated Plasma Protein A)
These values are combined with NT scan data to calculate a risk ratio for chromosomal conditions.
Why Is This Test Important?
- Early detection of potential genetic concerns
- Helps in personalized pregnancy planning
- Non-invasive, safe for both mother and baby
- Can reduce the need for unnecessary invasive procedures
Who Should Get This Screening?
It is recommended for all pregnant women, especially if:
- The mother is over 35 years
- There is a family history of chromosomal abnormalities
- The couple wants early reassurance about fetal development
What Happens If Risk Is Detected?
A high-risk result doesn’t confirm any condition—it only indicates the need for further testing, such as:
- Non-Invasive Prenatal Testing (NIPT)
- Chorionic Villus Sampling (CVS)
- Amniocentesis
Your doctor will guide you through next steps based on your results.
