Antenatal Testing Center

Antenatal testing is used to evaluate fetal well-being and placenta function in certain pregnancies. Your provider may recommend this testing if you have 糖尿病, hypertension (high blood pressure), an overdue pregnancy or advanced maternal age.

Specially trained registered nurses perform the tests using a fetal monitor and 超声波. The tests are comfortable and safe, and are usually repeated at intervals to monitor the baby's well-being over time. Most patients are seen once or twice a week.

The two main tests provided at the Antenatal Testing Center are the nonstress test (NST) and the amniotic fluid index (AFI). Together, they're called a modified biophysical profile (MBPP).

非压力测试(NST)

The NST is a method of assessing fetal well-being by observing the fetal heart rate response to fetal movement. 使用胎儿监护仪, so two small monitor parts will be fastened around your abdomen with soft belts. These parts are attached by cords to a monitor that records contractions and fetal heart rate. Your nurse will explain further and answer any questions during the test.

Amniotic Fluid Index (AFI)

An AFI uses an 超声波 machine to scan the uterus and measure the depth of fluid pockets. These measurements determine whether there's enough amniotic fluid around the baby. You'll be able to observe your baby during the 超声波. The nurses will review the findings with you after the exam.

Biophysical Profile (BPP)

A BPP is usually done only if more information is needed following the modified BPP. It's a five-part test that uses the fetal monitor and 超声波 to evaluate the NST and AFI, and the breathing movements, body movements and muscle tone of the fetus. The test is scored and will determine whether additional testing or evaluation is needed. The nurse will discuss the test with you and answer any questions you have.
