Brief Summary
Prenatal diagnosis can provide information to parents about specific fetal disorders. However, invasive prenatal diagnostic procedures are associated with risks to the fetus. This study will compare the safety and effectiveness of two methods of invasive prenatal diagnosis: amniocentesis and transabdominal chorionic villus sampling (TA CVS).

Eligibility Criteria
You may qualify if:
- Singleton pregnancy confirmed by baseline ultrasound
- At least 77 days gestation but not more than 104 days gestation confirmed by baseline ultrasound
You may not qualify if:
- Evidence of "vanishing" twin
- Bleeding equivalent to a menstrual period at any time during this pregnancy
- Medical history indicating serious maternal illness or potential teratogenic exposure
- Oligohydramnios
- Known fetal abnormality
- Dating inconsistency: if the estimated gestation is 8 or more days less than estimated by LMP, the patient is excluded unless interval growth by ultrasound confirms the normalcy of the pregnancy
