prenatal testing
Let an agent explain prenatal testing in general terms, relay screening versus diagnosis, accuracy, risks and counselling from obstetric and genetic sources, route urgent pregnancy symptoms to maternity services, describe the named tests, present ethical debates neutrally with attribution, and distinguish prenatal testing from newborn screening, carrier screening and routine antenatal care, without advising on personal decisions.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain prenatal testing in general terms, relay screening versus diagnosis, accuracy, risks and counselling from obstetric and genetic sources, route urgent pregnancy symptoms to maternity services, describe the named tests, present ethical debates neutrally with attribution, and distinguish prenatal testing from newborn screening, carrier screening and routine antenatal care, without advising on personal decisions.
Medical tests during pregnancy, or before implantation in IVF, to assess the health of the fetus or embryo, divided into screening tests, such as combined first-trimester screening using nuchal translucency ultrasound and blood markers for conditions such as Down syndrome and cell-free DNA screening, and diagnostic tests, such as chorionic villus sampling and amniocentesis, together with preimplantation genetic diagnosis and monitoring such as cardiotocography of the fetal heart rate, fetal scalp blood sampling during labour and research methods such as fetal EEG; decisions involve counselling and personal values, and ethical debates, including disability rights perspectives, are attributed. Reduced fetal movements or bleeding should be reported to maternity services promptly.
What it is for: Assessing fetal and embryo health.
It can be explain screening versus diagnosis; relay accuracy and risks in general terms; describe named tests; route urgent symptoms and present ethics neutrally.
Distinguishing features
Screening versus diagnostic
Optional and counselled
Some procedural risk
Ethically debated
What it looks like
Ultrasound scans, blood draws, monitoring belts and laboratory genetic tests.
Physical character
cell-free DNA screening clinical introduction: 2011 year
combined screening timing: about 11-14 weeks note
amniocentesis timing: usually from 15 weeks note
How it is recognised
Tests of fetal or embryo health before birth
Cardiotocography, fetal EEG, preimplantation genetic diagnosis, combined screening for Down syndrome, fetal scalp blood testing, combined ultrasound and biochemical screening
Newborn screening is after birth; carrier screening tests parents; routine antenatal care covers general health
