How we estimate "affects ~1 in N pregnancies"
The "1 in N" is an approximate UK total-birth prevalence - how often, across all births (live births plus stillbirths and terminations for fetal anomaly), a pregnancy is affected by one of the conditions this screen covers. We take the published birth prevalence of each condition, add them together, and express the total as "1 in N". The three autosomal trisomies are anchored to NCARDRS England 2022 (NHS England Digital).
This panel (3 conditions):
- Trisomy 21 (Down's syndrome) - 30.2 per 10,000 (≈1 in 331)
- Trisomy 18 (Edwards' syndrome) - 8.7 per 10,000 (≈1 in 1,150)
- Trisomy 13 (Patau's syndrome) - 3.4 per 10,000 (≈1 in 2,900)
Combined: 42.3 per 10,000 births ≈ 1 in 240.
This is a population detection rate, not your personal risk - your own risk depends on maternal age, family history and other factors, and a screen result is not a diagnosis. Because each test covers a different set of conditions, the figures are not directly comparable between tests.
