Non Stress Test
A non stress test is a simple, painless test that is used to evaluate your baby. A non stress test is usually done between weeks 38 and 42, but can but used as early as the beginning of the third trimester. The majority of women who have the test done have gone past their due date. Their caregiver orders the test to ensure the well-being of the developing baby. In some cases it is done as a precaution after problems in a previous pregnancy or because of high risk factors such as diabetes or intrauterine growth retardation.
This test is usually done in your doctor's office or hospital. You will sit in a chair or lie on a table with fetal monitoring equipment hooked to your belly. The monitor will record your baby's heart rate in conjunction with any uterine activity. During the test, your healthcare practitioner or a technician monitors your baby's heartbeat, first while the baby is resting and then while he's moving. Just as your heart beats faster when you're active, your baby's heart rate should go up while he's moving or kicking. You are generally asked to press a button when the baby moves so that the heart rate can be seen in relationship to that movement. .
Sometimes babies don't cooperate during the test and they move. The mother is usually offered a drink of something containing sugar or bubbles to perk the baby up. If this doesn't cause the baby to move sometimes a loud sound will be used to startle the baby into moving. Remember babies can and do sleep in utero.
