How do you interpret BPP results?
Biophysical Profile Test Score Results A total score of 10 out of 10 or 8 out of 10 with normal fluid is considered normal. A score of 6 is considered equivocal, and a score of 4 or less is abnormal [1,3, 6]. A score of less than 8 indicates the fetus may not be receiving enough oxygen.
What does a low BPP mean?
The results of each part of the test — heart rate, breathing, body movement, muscle tone, and amount of amniotic fluid — are added up to form a total score. A score of eight to 10 means your baby seems healthy. Scores lower than eight usually mean that you need retesting.
What makes it a high risk pregnancy?
High blood pressure, obesity, diabetes, epilepsy, thyroid disease, heart or blood disorders, poorly controlled asthma, and infections can increase pregnancy risks. Pregnancy complications. Various complications that develop during pregnancy can pose risks.
How accurate is BPP?
To summarize the results of multiple studies, the false-negative rate of a normal BPP is less than 0.1%, or less than 1 fetal death per 1000 within 1 week of a normal BPP.
What is a positive contraction stress test?
A contraction stress test tells you whether your baby’s heart rate slows down: Normal (negative) results mean your baby’s heart rate doesn’t stay slow after a contraction (late decelerations). Abnormal (positive) results mean your baby’s heart rate slows down and stays slow after a contraction.
What gestational age does BPP start?
The timing of the study is recommended to start at 32 weeks gestation for most fetal and maternal conditions. If there are multiple or severe conditions, antenatal testing can begin earlier.
When should you repeat BPP?
if <36 weeks initiate continuous fetal monitoring, repeat BPP in 4 hours, if repeat ≤4, deliver.
How do you read a pregnancy stress test?
CST Results
- Positive: Abnormal findings indicate a fetal heart rate that slows down and stays slow after the contraction for more than half of the contractions.
- Negative: A normal test shows fetal heart tones that do not decelerate during or after contractions.
- Equivocal: Results of the test are sometimes unclear.
Why is a BPP done in pregnancy?
A biophysical profile (BPP) measures the health of your baby during your pregnancy. The BPP checks your baby’s heart rate, muscle tone, movement, and breathing. It also measures the amount of amniotic fluid around your baby.
