Maternal blood draw : A standard blood draw from the pregnant person - no risk to the pregnancy.
Test suitability
Test suitability
Suitable for singleton pregnancies. If you are expecting twins or have used donor eggs or a surrogate, please speak to our midwife before ordering. Best performed between 10 and 16 weeks of pregnancy.
Not suitable for pregnancies beyond 16 weeks, triplet (or higher-order) pregnancies, or where the patient has a history of chromosomal abnormalities, parental mosaicism, fetal demise, an active malignancy, or a previous bone marrow / organ transplant.
Genetic testing with Jeen Health is only available to individuals aged 18 and over.
⚠ If your pregnancy has progressed beyond 16 weeks, please reach out before booking. Our genetic counsellors will discuss your circumstances and recommend the most suitable option.
Three steps. That's it.

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 adds to the combined figure.
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 pregnancy of adequate gestational age, confirmed by a recent scan, before a sample is taken. Suitable for singleton pregnancies. If you are expecting twins or have used donor eggs or a surrogate, please speak to our midwife before ordering.
