I want to ask you about my Level 2 scan.

Question

Accepted Answer

An increased nuchal fold thickness during pregnancy can be a marker for certain chromosomal abnormalities, particularly Down syndrome (Trisomy 21). The nuchal translucency (NT) measurement is often taken during the first-trimester screening, typically between 11 and 14 weeks of pregnancy. It is the fluid-filled space at the back of the baby's neck.

Here are some key points regarding an increased nuchal fold thickness:

1. **Normal Range:**
   - In a healthy pregnancy, the nuchal translucency measurement is within a certain normal range. An increased thickness may be a cause for concern.

2. **Combined First-Trimester Screening:**
   - The nuchal translucency measurement is often combined with blood tests (PAPP-A and hCG) to provide a more comprehensive assessment of the risk of chromosomal abnormalities.

3. **Follow-Up Testing:**
   - An increased nuchal fold thickness may prompt further testing, such as chorionic villus sampling (CVS) or amniocentesis, for a more definitive diagnosis. These tests can analyze the baby's chromosomes to determine if there are any abnormalities.

4. **Soft Markers:**
   - The nuchal fold thickness is considered a soft marker, and its presence alone does not confirm a chromosomal abnormality. Many pregnancies with increased nuchal translucency results go on to have normal, healthy babies.

5. **Consultation with Genetic Counselor:**
   - If there are concerns about the nuchal translucency measurement, it's crucial to consult with a healthcare provider and possibly a genetic counselor. They can provide information about the risks, potential outcomes, and available testing options.

6. **Ultrasound Accuracy:**
   - The accuracy of the nuchal translucency measurement can be influenced by factors such as gestational age, the position of the baby, and the skill of the sonographer. Follow-up testing is often recommended to confirm results.

It's important to note that while an increased nuchal fold thickness can be associated with chromosomal abnormalities, it does not guarantee that the baby has a specific condition. Many pregnancies with soft markers go on to result in healthy babies. The decision to undergo further testing is a personal one, and healthcare providers can offer guidance based on individual circumstances.
