Nuchal translucency and first-trimester screening

This ultrasound measurement may be one part of a screening pathway; timing, accompanying blood tests and interpretation vary.

Direct guidance

What to know or do

Ask what is being measured, the valid timing window, when results arrive and what follow-up would be offered for an unexpected result.

What changes the answer

  • Whether this is screening, diagnosis, monitoring, treatment or birth planning
  • Pregnancy week, previous results and what the result could change
  • Benefits, limits, alternatives, follow-up and the time available to decide

When to get individual help

Check the exact item or situation with a doctor, midwife, pharmacist or relevant clinician; the name of a broad category is not enough for a personal decision.
