What is the one test of greatest predictive value for the fetus? Afp?

Maternal-Fetal Medicine 47 years experience
Prediction?: Predictive value for what? A high AFP is associated with a fetus with a neural tube defect. A large nuchal translucency is associated with chromosomal abnormalities and cardiac defects. A normal level ii ultrasound reduces the risk of structural abnormalities in the fetus. So it depends upon what you are testing for.

How do you know for sure if a fetus is Rh sensitized?

1 doctor answer2 doctors weighed in
Dr. Dennis Higginbotham
Obstetrics and Gynecology 30 years experience
It isn't: In the case of rh disease, it is the mother that is sensitized. The fetus is at risk for anemia due to maternal anti-rhesus antibody crossing the placenta. If the fetus is rh negative, there will be no problem. The blood type of the fetus isnot usually determined until after delivery. There is research into determining fetal blood type from mom's blood - but that is not yet available.

Chromosomes: What is "a little bit"? Lack of some chromosomal material may be associated with an unbalanced chromosomal complement. That is not normal and depending upon what chromosomal material was lost may affect the way the fetus develops and functions.

Does listening to classical music make my fetus smarter?

No: Classical music can be very relaxing and pleasant so if it helps you during your pregnancy, go for it. The fetus is mostly listening to your heartbeat and intestinal motion sounds.
