When preparing for delivery, an expecting parent must undergo a host of tests and procedures to confirm the appropriate development of the fetus. It is integral to understand the purpose of these procedures required by most healthcare providers. A common term you may come across is biparietal diameter (BPD), often involved in ultrasound examinations during pregnancy. Read on to understand the biparietal diameter meaning.

What Is The Biparietal Diameter?

The biparietal diameter (BPD) is one of the measurements obtained from an ultrasound scan, usually taken during the second trimester of pregnancy. It represents the distance between two sides of the fetus's head. This indicator helps healthcare providers estimate the fetus's size and growth rate. By matching BPD with set growth charts for babies, doctors can determine whether the fetus is growing normally.

Understanding the definition of biparietal diameter with regard to your health insurance will enable you to make well-informed decisions regarding your healthcare coverage. The biparietal diameter may also be used to treat complications that may arise during pregnancy. Therefore, understanding these concepts is advantageous if you are reviewing your policy or looking at new choices in preparation for delivery.

Conclusion

The biparietal diameter is an essential parameter during pregnancy ultrasound check-ups. When expecting parents understand its use in fetal development tracking, they may take appropriate precautions and make conscious decisions regarding insurance coverage.
