To calculate the GA and the EFW by measuring a specific part of a fetus, an accurate reference
must be selected.

If the EFW Reference of the ACCUVIX XG is changed, the existing EFW is recalculated with the
new reference and then shown on the report. Therefore, it is recommended that you do not
change the EFW Reference of a patient.

Since multiple GAs and EFW References are provided, the specialist must make a choice based
on his or her clinical judgment. Choosing an inappropriate reference may result in incorrect
measurements.

When performing an exam, one must bear in mind that measurements may vary depending on
the posture of the fetus.

In cases where there are multiple fetuses, be sure to verify the Fetus ID to avoid confusion.
