3D Ultrasound Biophysical Profile

A biophysical profile (BPP) ultrasound is a noninvasive test in late pregnancy that evaluates fetal well‑being by combining an ultrasound exam with a fetal heart‑rate (non‑stress) test. It scores five components—fetal breathing, body movements, tone, amniotic fluid volume, and heart‑rate reactivity—each 0 or 2, producing a 0–10 score. Low scores suggest possible fetal distress and may prompt closer monitoring or delivery.

You can have a 3D ultrasound as early as about 20 weeks, but the best time for clear facial and body detail is usually between 26 and 32 weeks. Before 26 weeks there’s less fat under the skin; after about 32–34 weeks the baby’s position and reduced fluid can limit images. Discuss timing and safety with your healthcare provider and choose a qualified sonographer.

A biophysical profile score of 3/10 is abnormal and suggests significant fetal compromise. It reflects few reassuring findings on ultrasound and nonstress testing, often indicating possible hypoxia or fetal distress. This result typically prompts immediate re-evaluation, intensified monitoring, and consideration of urgent interventions or delivery depending on gestational age and clinical context.

Yes. 3D ultrasound can often determine fetal sex, usually from about 16 to 20 weeks but is most reliable around 18 to 20 weeks. It provides clearer surface anatomy than 2D, improving visualization of genitalia. Accuracy depends on gestational age, fetal position, maternal body habitus and operator experience, so it isn’t 100% certain and may be inconclusive.

A biophysical profile is recommended for pregnancies at increased risk of fetal compromise — for example, reduced fetal movements, an abnormal non‑stress test, suspected growth restriction, oligohydramnios, post‑dates, maternal conditions like diabetes, hypertension or preeclampsia, multiple‑pregnancy complications, prior stillbirth, or other concerns about fetal well‑being to monitor and guide management.

Costs vary by country and setting. In the U.S. a biophysical profile typically costs about $200–$1,200 (commonly $300–$500 out-of-pocket depending on insurance). In the U.K. it’s usually free on the NHS; private clinics charge roughly £100–£250. In India private clinic fees range roughly ₹1,000–₹5,000. Coverage, regional rates and added facility fees can change the final price.
