B) At 16 to 20 weeks, we perform a non-invasive AFP
(Alpha Fetal Protein) blood test, that screens for spinal
bifida. Some patients who opted out of the 1st trimester screen
Nuchal Fold test, may have the Quad Screen, which is a non-invasive
blood test that also screens for Down syndrome and other trisomies. The
invasive test at 16 weeks or later is called the Amniocentesis. This test involves a
needle into the amniotic sac of the baby and checks the fetal chromosomes and for
spinal bifida. This is an invasive test, it is more accurate, but carries a risk for miscarriage. Some patients opt for this test.
C) At 19-20 weeks, patients usually get a second trimester ultrasound. At this ultrasound, the baby will be measured from head to toe. The four chambers of the heart will be viewed, as well as the kidneys, bladder, stomach, brain, spine, and sex organs (be sure to tell your sonographer if you don’t want to know the sex of the baby!).
D) At 24-28 weeks, patients usually get tested for Gestational Diabetes and anemia. Patients who are RH Negative blood type, usually get the Rhogam shot. Also, the Whooping Cough shot (Tdap) is discussed and offered to everyone.
E) At 28 weeks you can choose to pay for beautiful, keep sake 3D/4D ultrasound pictures. (Not covered by insurance).
F) At 35-37 weeks, we do a third trimester ultrasound to calculate the baby’s weight.
G) At 35-36 weeks, patients get the Beta Strep culture and we start weekly vaginal exams.
Along the way, if you have a specific or acute problem, we may see you more often or for a ‘sick visit’. Sometimes, we may direct you to the hospital for evaluation.
