How do you calculate fetal weight?

log10(Fetal weight) = 1.3596 – (0.00386 * AC * FL) + (0.0064 * HC) + (0.00061 * BPD * AC) + (0.0424 * AC) + (0.174 * FL) , where: Fetal weight is given in grams (g); AC means the Abdominal Circumference and is given in centimeters (cm);

How can I measure my baby’s weight at home?

The simplest way to gauge a baby’s size in utero is to measure an expecting mom’s fundal height. Fundal height measures the distance from your pubic bone to the top of your uterus in centimeters. Your health care practitioner will also palpate your abdomen to get an idea of your baby’s size.

How is baby’s weight determined by ultrasound?

Ultrasound uses volumes to calculate fetal weight. It takes measurements of the head, waist circumference and some bones and comes up with an estimate. But it can’t measure the density of the fetal tissues directly.

What is sonographic estimated fetal weight?

Sonographic fetal weight could be predicted by measuring one fetal parameter such as the Biparietal diameter (BPD), Abdominal Circumference (AC), Femur Length (FL), and Head Circumference (HC) or by a combination of several of these fetal parameters.

How accurate are ultrasounds?

How accurate is the ultrasound examination? The earlier the ultrasound is done, the more accurate it is at estimating the baby’s due date. Ultrasounds performed during the first 12 weeks of pregnancy are generally within 3 – 5 days of accuracy. The most accurate time is between 8 and 11 weeks gestation.

How accurate is fetal weight estimation by ultrasound?

These are the biparietal diameter, head circumference, abdominal circumference, and femoral length. Ultrasound estimation of fetal weight, while being accurate to a degree, is associated with error ranging from ±6 to 11% depending on parameters measured and the equation used for estimation [7].
