Hi, dear. I have gone through your question. I can understand your concern. You have foetal biometry. It will give different parameters. Like biparietal diameter, head circumference, abdominal circumference, femur length etc. These all are different parameters so all have different results and they are variablr according to gestational age. We should compare with gestational age. Your all value are normal. No need to worry about that. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using health care magic. Wish you a very good health.
