# Biophysical Profile (BPP) Source: https://www.pregnancypowerhour.com/tests/biophysical-profile Last updated: 2026-07-01 > The Biophysical Profile (BPP) is a late-pregnancy ultrasound and Non-Stress Test that assesses fetal wellbeing, often recommended for high-risk pregnancies. The Biophysical Profile (BPP) is a comprehensive late-pregnancy assessment that combines an ultrasound with a [Non-Stress Test (NST)](/tests/non-stress-test) to evaluate your baby's wellbeing, particularly when there are specific concerns. This test offers a deeper look into how your baby is doing, moving beyond a simple snapshot to assess several key indicators of health and comfort within the womb. ## What it is A BPP is designed to give your care team a clearer picture of your baby's health by observing five distinct components. Four of these are assessed through a specialized ultrasound: fetal breathing movements, fetal body movements, fetal tone (like opening and closing a hand), and the volume of amniotic fluid surrounding your baby. The fifth component is the [Non-Stress Test (NST)](/tests/non-stress-test), which monitors your baby's heart rate in response to their own movements. Each of these five components is scored either 0 or 2, contributing to a total score out of 10. This structured scoring system helps provide an objective measure of your baby's current status. ## When and how it happens The BPP is typically recommended in the third trimester, generally from week 28 onwards, and falls under the 'late-pregnancy' category. It's important to understand that a BPP is not a routine test for low-risk pregnancies. Instead, it's specifically indicated for situations where there's a higher risk involved, or if you've noticed decreased fetal movement. This might include conditions like gestational diabetes, preeclampsia, or if you have certain blood incompatibilities that might require monitoring, such as those managed with [RhoGAM (Anti-D Immunoglobulin)](/tests/rhogam-rhd-antibody). If your pregnancy has gone past your due date, a BPP may also be considered. The American College of Obstetricians and Gynecologists (ACOG) guidelines emphasize that routine BPPs are not recommended for those with low-risk pregnancies, underscoring its role as a targeted assessment. The test itself involves lying comfortably while a sonographer performs the ultrasound and places external monitors on your abdomen for the NST. It's a non-invasive process, designed to gather information without discomfort. In some cases, your provider might recommend a 'Modified BPP.' This version focuses on two key indicators: the [Non-Stress Test (NST)](/tests/non-stress-test) and an assessment of your amniotic fluid volume. This modified approach is often used for routine monitoring in certain high-risk pregnancies, providing a streamlined yet effective way to keep an eye on your baby's wellbeing. ## What the results mean Understanding your BPP score can help you and your provider make informed decisions about your care. A score between 8 and 10 out of 10 is generally considered reassuring, suggesting that your baby is doing well. If the score is 6, it's often considered equivocal, meaning the results are neither clearly reassuring nor concerning. In this situation, your provider might suggest repeating the test within 12 to 24 hours to see if there's any change. A score of 4 or below is considered concerning and may prompt further evaluation or even a discussion about the possibility of early delivery, depending on your specific circumstances and gestational age. Your provider might also consider additional assessments, such as an [Umbilical Artery Doppler](/tests/umbilical-artery-doppler) to check blood flow, to gather more information. Remember, these scores are tools to guide conversation and decision-making, always in collaboration with your care team. ## Questions worth asking When a BPP is recommended, it's a wonderful opportunity to engage in a collaborative conversation with your care provider. Here are some questions you might consider asking to gain clarity and feel confident in your decisions: * What are the specific reasons this BPP is being recommended for me at this time? * What are the potential next steps or management options based on the different possible scores? * Are there any alternative monitoring approaches or additional tests we should consider, like an [Umbilical Artery Doppler](/tests/umbilical-artery-doppler)? * How will these BPP results potentially influence my birth plan or preferences? * Who will be explaining the results to me, and how quickly can I expect to receive them? Your care provider is your best resource for your specific situation. Asking these questions can help you feel grounded and informed as you navigate this part of your pregnancy journey. You get to decide what feels right for you and your baby.
