A simple blood draw could one day detect down syndrome in pregnancy
Diagnosis Recruiting nowResearchers are collecting blood samples from pregnant women at higher risk of having a baby with a chromosomal condition. The goal is to develop a noninvasive prenatal test that looks at cell-free DNA in the mother's blood to detect Down syndrome. Participants give blood between…

New prenatal blood test aims to detect genetic disorders without invasive procedures
Diagnosis Recruiting nowThis study is testing a new blood test that looks for fetal cells in the mother's blood to detect genetic conditions like Down syndrome. The test will be compared to standard diagnostic methods such as amniocentesis or newborn testing. The study involves 1,000 pregnant individual…

Can 'Abnormal' embryos still lead to healthy pregnancies? a new registry investigates
Knowledge-focused Recruiting nowThis registry study follows 1,000 people who plan to transfer a non-euploid embryo—one with an abnormal number of chromosomes—at fertility clinics in The Prelude Network. The goal is to track how often these embryos implant and result in a positive pregnancy test. By gathering th…

Labelled 'Abnormal' but born healthy? new study tests embryo genetic test accuracy
Knowledge-focused Recruiting nowThis study looks at embryos that were found to have extra or missing chromosomes (aneuploidy) or a mix of normal and abnormal cells (mosaicism) during genetic testing. Researchers want to see how often these embryos lead to a healthy baby and whether the pregnancy or child has an…

Second look at 'Abnormal' embryos could unlock hidden IVF potential
Knowledge-focused Recruiting nowThis study is re-testing embryos that were initially found to have three or more abnormal chromosomes (called complex or chaotic aneuploidy). Researchers want to see if some of these embryos are actually normal after a second, more careful biopsy and genetic analysis. If so, they…
