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 add the published birth prevalence of each condition (or condition class) and express the total as "1 in N". The three autosomal trisomies are anchored to NCARDRS England 2022.
This panel:
- Trisomy 21 / 18 / 13 - 42.3 per 10,000 combined (≈1 in 240)
- Trisomy 15 / 16 / 22 (almost always miscarry; residual at birth) - ~0.3 per 10,000
- Sex-chromosome aneuploidies (Turner, Klinefelter, Triple-X, XYY), combined - ~17 per 10,000 (≈1 in 580)
- 22q11.2 deletion plus eleven further microdeletions, combined - ~7 per 10,000
- ~20 de-novo dominant single-gene disorders (e.g. Noonan, achondroplasia, Rett, Cornelia de Lange), combined - ~17 per 10,000 (≈1 in 600)
Combined: ~84 per 10,000 births ≈ 1 in 110. The de-novo single-gene panel is what makes KNOVA the broadest - and commonest-detecting - screen in the range.
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.

Three short questions so the lab can run NIPT reliably - every NIPT panel needs a confirmed singleton or twin pregnancy of adequate gestational age before a sample is taken.
