What Happens After an Abnormal NT Scan?
An abnormal NT scan raises a question and does not give a final answer. Here is how doctors usually work through it, step by step.

A positive NIPT result is a high-risk screening result, not a diagnosis. Here are the next steps: counselling, a detailed scan and confirmatory testing.

Getting a positive result is stressful. It helps to remember that NIPT is a screening test. Some positive results turn out to be false alarms, and confirmation is always needed before any decision is made.
A fetal medicine specialist will explain what was found, which chromosome is involved, and what the result may mean. This is the time to ask every question you have.
A targeted scan checks the baby's growth and structure. It may show signs that support or reduce the concern, and it helps plan the next steps.
To get a definite answer, one of these is usually offered:
These tests carry a small risk of miscarriage, which your doctor will discuss with you. They are done under ultrasound guidance.
If the diagnostic test is normal, the NIPT result was a false positive and the pregnancy continues with routine care. If it confirms a condition, your doctor will explain what it means for the baby, what care is available and what options you have, without pressure.
Waiting for answers is hard, and you do not need to go through it alone. Dr Malathi G. Prasad at Trichy Fetal Medicine and Fertility Centre in Trichy offers counselling and the confirmatory testing that families need at this stage.
For appointments, the genetic counselling page has the details, and our fetal medicine specialists can advise whether it fits your situation.
