  • Breathing
  • Quantity of amniotic fluid surrounding the baby
  • Muscle tone
  • Movements
  • To ensure there is required quantity of oxygen inside your womb

  2. Keep a check on your fetus if you happen to have a “high risk pregnancy” or a history of
What Preparation Is Required For The Test?

Not much preparation is required before the test is normally conducted. Like most other pregnancy tests, one requires to have a bladder that is full before the test. However, if you happen to be in the final trimester of the pregnancy, a full bladder is also not required. Sometimes they ask you to eat a good meal just before the test is conducted so that the fetus inside you gets stimulated to move around a little more than usual.

How Is The Test Done?

For the test, you are made to lie down on the examination table. They check your blood pressure levels before the test begins. A belt is positioned across the stomach and it comprises of a sensor that assesses the heart rate of the fetus. This test normally takes around twenty minutes overall. However if the fetus is asleep, you may require waiting for the little one to wake up to get proper results. They spread a gel on the tummy and a tiny monitor is rotated all over the abdomen several times. After the test the gel will be wiped clean and the scores will be revealed.

What Do The Results Of The Test Reveal?

Every component or parameter that includes breathing, muscle tone, heartbeat, amniotic fluid and body movements are all assigned a score anywhere between 0 (abnormal) and 2 (normal) They are all added up to get the total score out of 10.

  • A score anywhere between 8 and 10 is considered safe and perfectly normal
  • Somewhere around six is supposed to be border line
  • Scores below six shows there is something wrong that requires immediate attention
  • Scores below 4 indicates you need extra tests or that an emergency delivery requires to be performed at once

Suppose the ultra sound show no cause for worry, the doctor may not advise a non stress test. But if the scores of amniotic fluid results to a zero, more testing is immediately required and even immediate delivery may be recommended although all other scores are normal.

Risks Associated With Bio Physical Profile Test

Lengthy periods of ultra sound are the only cause for concern. However abnormal scores tend to make you worried and anxious. And there is every chance that an existing abnormality may go undetected in this test. There have also been cases where this test revealed a problem when actually everything was perfectly normal.

What Affects The Test Results?

There are some resons that may affect the test result or make it difficult to conduct the test itself. Some of them include:

  • Position of the baby makes it difficult to do the ultrasound
  • It the pregnant woman is unable to lie still throughout the procedure as it requires lying on the baby, then this can lead to the ultrasound picture of the baby being unclear
  • If the mother to be is overweight, then it makes it difficult to correctly position the external monitoring device
  • If either the mother to be or the baby has any kind of infection
  • High or low blood sugar levels
  • On a medication like magnesium sulfate
  • Steroids being administered to the fetus to help the lungs to mature
  • If the pregnant woman is consuming alcohol or any illegal drugs
  • Very rarely the stool or air in the rectum or intestine may interfere with the fetal ultrasound
