NT scan and First trimester screening

First trimester combined Screening: FTS (Done between 11 weeks to 13 weeks) Down syndrome and Preeclampsia

  • A Screening test is a basic test to understand if there is risk for a condition.
  • FTS involves a scan and a blood test – to evaluate the risk of having a baby affected by a common (1:700) chromosome defect called ‘Down syndrome’ and also risk of developing blood pressure in pregnancy.
  • FTS involves a scan and a blood test – to evaluate the risk of having a baby affected by a common (1:700) chromosome defect called ‘Down syndrome’ and also risk of developing blood pressure in pregnancy.
  • Down syndrome babies have an extra copy of chromosome 21 and can have development delays and learning difficulties. Some may also have heart and kidney disease.
  • The scan involves detailed assessment of your baby to ensure normal growth and development of the organs, expected for the 13 weeks.
  • The scan markers checked are “Nuchal translucency (NT)” (fluid accumulation in the neck) and the appearance of the baby’s “nasal bone” (nose bone).
  • We also assess the blood flow to your baby.
  • The blood test checks for proteins that the placenta produces. The blood markers checked are PAPP-A, HCG and PLGF.
  • Your age and the information from the scan and blood tests are used to work out the chance of the baby having Down’s syndrome, Edwards’ syndrome or Patau’s syndrome.
  • In a place where the scan is done as per standards, then the detection rate of the FTS test can be up to 90%
  • If the final risk is “Low”- It means there is a very low chance of the baby affected- No further test is required
  • If the final risk is “Intermediate”- It means the risk is low but cannot be conclusively taken as reassuring and further advanced screening can be opted.
  • If the final risk is “high”- There is a high chance of the baby to be affected. DOES NOT MEAN THAT THE BABY IS AFFECTED. Further confirmatory test is required, which will be discussed. Please speak to the doctor for further clarifications. Best Wishes!

Anomaly scan

  • Detailed assessment of the baby’s organ development, growth and circulation based on standards given by the fetal medicine foundation.
  • If there is a defect identified clear explanation, and available treatment options will be discussed in detail.

Growth Scan

  • Assessment of the fetal weight gain using measurements taken during the scan. The baby is expected to gain certain grams of weight each week and understanding adequate weight gain is important, especially in the third trimester.

Fetal Doppler Study

  • Fetal Doppler study checks fetal blood circulation in the vital organs, such as the placenta, brain and heart. As much as adequate weight gain is important, good fetal circulation ensures that the baby is healthy.

Fetal Echocardiogram

  • Detailed assessment of the baby’s heart. This is done only for specific indications, when there is a medical condition in the mother or complications suspected in the baby’s heart.

Fetal Neurosonogram

  • Detailed assessment of the baby’s brain. This is done only for specific indications, when there is a suspected abnormality in the baby’s brain.
