lmp date on ultrasound
I just noticed the date on my u/s back in march for lmp is 11/13/10 do the drs put that date in or does the machine when they measure the baby because my actual lmp was 11/2/10 which would change my due date. I am just trying to figure out if the doc messed up or what is going on.
The tech puts in the info for lmp, the machine will calculate gestational age based on crown to rump length measurements for early pregnancy or for later pregnancy a combination of femur length, abdominal circumference, head circumference and a few other determining factors. I would mention it to the doc and see what s/he says.
Usually the doctor or technician puts the LMP date in. The machine generally only calculates a gestational age based on certain measurements.
