first trimester screen
Early pregnancy test
A first trimester screen is a prenatal test performed during the first three months of pregnancy to assess the risk of chromosomal abnormalities like Down syndrome.
It typically combines a blood test measuring certain proteins with an ultrasound measuring fluid at the back of the fetus's neck.
The screen estimates probability rather than providing a diagnosis: The first trimester screen came back low-risk.
