If a woman chooses to have NIPS (non-funded) as their primary screening test, knowledge of dates is required.
The woman should still proceed with a scan at 12 to 14 weeks gestation for assessment of fetal anatomy and for other benefits.
However, NT measurement (and combined screening assessment) is not recommended in women with a previous NIPS result (Note: The NT should still be measured if it appears increased, and Fetal Medicine or other local equivalent specialist referral should be offered if NT is ≥3.5 mm.).
A woman may choose to have NIPS (non-funded) following combined screening assessment.
