Whole Blood Specimen Collection From Pregnant Subjects

To obtain whole blood specimens from pregnant subjects to be used for research and development and clinical validation studies of prenatal assays.

This sample collection protocol allows for the identification, recruitment, and participation in women who are pregnant and are known to:

1. be at an increased risk for fetal genetic abnormalities
2. be at increased risk for congenital fetal infection by virtue of being positive by initial screening tests, or are known to have an active infection during this pregnancy.
3. possess irregular blood group antigens (the subject or the father of the baby) and are therefore at increased risk for fetal sensitization during this pregnancy.

• Subject is pregnant carrying a singleton fetus of 10 to 26 weeks gestational age inclusive
