### What is a Biophysical Profile (BPP)? A Biophysical Profile (BPP) is a combination of tests used to check the health of your baby during pregnancy. It is often recommended if you are past your due date or have a higher risk of complications. These risks can be due to health conditions like diabetes or preeclampsia, or after an accident to ensure the baby's well-being. ### What Does BPP Measure? The BPP measures several aspects of your baby's health: - **Body Movement:** Checks how often your baby moves. - **Muscle Tone:** Assesses your baby's muscle strength. - **Heart Rate:** Monitors how fast your baby's heart rate accelerates during movement. - **Amniotic Fluid:** Measures the amount of amniotic fluid surrounding your baby. ### How is BPP Conducted? The BPP is safe and non-invasive, lasting about 30 minutes. It includes two main parts: - **Ultrasound:** Tracks your baby's movement and measures the amniotic fluid. You'll lie on your back while a technician uses an ultrasound wand on your belly. - **Nonstress Test:** Monitors your baby's heartbeat for 20 minutes. An elastic band with two sensors is placed around your belly—one to pick up the baby's heartbeat and the other to monitor contractions. Some doctors may start with just the ultrasound and add the nonstress test if more information is needed. ### Understanding BPP Scores The results from each part of the test—heart rate, breathing, body movement, muscle tone, and amniotic fluid—are combined to form a total score. - **8 to 10:** Your baby seems healthy. - **Below 8:** Retesting may be needed. - **Very Low Score:** Could indicate distress, and early delivery might be recommended. ### When is BPP Done? If your doctor decides you need a BPP, it will likely be done in the last trimester, though some women may have it earlier. Follow-up BPPs may be suggested for the rest of your pregnancy.
