Patients receive an evaluation by a perinatologist (a maternal-fetal
medicine specialist), who assesses risk in pregnancy and helps patients
plan for a current or future pregnancy.
a noninvasive test that uses sound waves to visualize the fetus in
utero. This simple procedure can be used to help confirm gestational
age, monitor growth, identify some abnormalities and evaluate the
well-being of the fetus.
The first-trimester/sequential screening utilizes both ultrasound
findings and maternal hormone levels to determine if a woman is at
increased risk for having a baby with Down syndrome (trisomy 21) or
Doppler Flow Studies
A Doppler flow study uses
ultrasound to evaluate the blood flow to the placenta from the fetus and
the mother. This is usually done in conjunction with a complete
ultrasound study of the fetus.
Tests for Fetal Well-Being
A biophysical profile (BPP),
which includes a nonstress test (NST), evaluates how well
the placenta is providing oxygen to the fetus. The information obtained
helps determine or predict the well-being of the fetus.
A genetic counselor, under the supervision of a perinatologist, is
available to consult with patients to assess genetic risk and provide
information about various genetic testing options.
Chorionic Villus Sampling
Chorionic villus sampling
(CVS) is performed early in a pregnancy by sampling tissue from what
will become the placenta. This tissue is evaluated for possible genetic
or chromosomal abnormalities and can provide reassurance to parents. If
you undergo a CVS, you should limit your activity for the rest of the
day following the procedure. DO NOT exercise or lift anything heavy the
day of the procedure. Specimens take approximately 10 to 12 days to
Amniocentesis is used to
obtain amniotic fluid for genetic evaluation and information about fetal
development. If you undergo an amniocentesis, you should limit your
activity the rest of the day following the procedure. DO NOT exercise or
lift anything heavy the day of the procedure. Specimens take
approximately 10 to 12 days to process.
